microHAM © 2010 All rights reserved 4 - INSTALLATION Installing MK2R consists of several steps: 1) prepare MK2R to work with your radios 2) install microHAM USB Device Router (the control and interface software) 3) configure the Windows USB Audio Devices (MK2R+ Only) 4) configure Router 5) set audio levels Preparing MK2R for Use 1. Turn off both radios and make MK2R rear panel accessible. 2. Plug the DB37M of one radio cable set into the RADIO1 connector on the rear panel of the MK2R.
microHAM © 2010 All rights reserved 10.
microHAM © 2010 All rights reserved Configuring USB Audio CODEC and USB Voice CODEC (MK2R+ only) Windows will automatically install the USB Audio Device driver to support the USB Audio CODEC and USB Voice CODEC in MK2R+ Windows automatically selects any newly installed audio device as the default device for Sound Playback and Sound recording. This is undesirable as Windows Sounds would be played through MK2R+ and onto the air! For Windows 2000 or Windows XP.
microHAM © 2010 All rights reserved For Windows Vista and 7, right click on the Speaker Icon on the task bar and select "Playback Devices” or open “Sounds” in Control Panel and reset the Default Playback device to your computer's primary sound device.
microHAM © 2010 All rights reserved Configuring microHAM USB Device Router The microHAM USB Device Router (Router) program provides a Windows compatible configuration tool for microHAM USB Devices (MK2R or MK2R+ as well as DIGI KEYER, microKEYER, CW Keyer and USB Interfaces) and software interface to other Windows applications (logging software, digital mode software, etc.). The software interface is provided as Virtual Serial Ports.
microHAM © 2010 All rights reserved Creating and Using Virtual Serial Ports microHAM Router provides a set of virtual serial ports which allow Windows applications (logging and digital software) to work with MK2R just as they would work with "real" (hardware) serial ports. In order to use these virtual Ports, you must first create the ports and then assign a port to each function you wish to use (radio control, PTT, CW, FSK, etc.).
microHAM © 2010 All rights reserved 5. microHAM USB DEVICE ROUTER ROUTER MENU Default Router Settings: used to completely reset Router to factory (default) settings. "Default" removes all device tabs and deletes all stored configuration data, including all user presets from the Windows Registry. TIP: The MK2R/MK2R+ can be completely reset by selecting Default Router Settings followed by Device | Store as Power-up Settings to save the defaults to the controller's EEPROM.
microHAM © 2010 All rights reserved Options | USB: Noise immunity: selects how many times an undelivered USB packet will be repeated before the USB device is disconnected from the operating system. Response time: selects how long the USB interface will wait for additional data before sending data to the operating system. Minimize: Clicking this will minimize Router to the system tray at the bottom right corner of the Windows Task Bar (the "System Notification Area").
microHAM © 2010 All rights reserved 3. By right clicking on the system tray icon when the Router is minimized. 4. The presets and the current router configuration are stored to the registry when Router is closed and recalled when Router is loaded. Save as - Saves the current Router settings to a preset for future use. Rename - Allows renaming of an existing preset. Delete - Delete chosen preset. Show buttons - When checked, Router shows the preset buttons. DEVICE MENU Router can control several devices.
microHAM © 2010 All rights reserved Store as Power-Up Settings: - will store the current settings of the Audio Switching, PTT, CW/WinKey, SO2R and ACC tab to the MK2R EEPROM. If MK2R is operated without connection to the computer it will use the settings stored in EEPROM. If MK2R is connected to a computer running Router, the Router settings will be used but the default settings are retained in EEPROM. Upload Firmware: microHAM will occasionally release updates to the firmware in MK2R.
microHAM © 2010 All rights reserved VIRTUAL PORT MENU It is necessary to create a number of virtual serial ports (COM ports) in order for a Windows application (logging, control or digital mode program) to access microHAM devices. Create - Creates virtual COM ports. It is possible to select more ports at once by holding the Control key on the keyboard and clicking on COM port numbers. Creating a virtual port may take a while, be patient. Delete - Deletes any single virtual port.
microHAM © 2010 All rights reserved DEVICE CONFIGURATION TABS There are twelve (12) tabs for configuring MK2R. Each tab controls part of MK2R's functions. Except for CW Messages, FSK Messages and Functions tabs, any change is applied immediately to MK2R.
microHAM © 2010 All rights reserved PORTS TAB Once the virtual ports have been created they must be associated with a specific function or device channel (e.g., Control, CW, PTT, etc.). These assignments should correspond to settings of the application software and must be configured first in Router then in the application. Proper port configuration is critical for operation with application software.
microHAM © 2010 All rights reserved CAT PORT & 2nd CAT PORT The CAT channel is used by the host application to control transceiver frequency, mode, T/R switching and many other parameters. The application communicates with the radio using a serial protocol. Most modern radios implement some form of serial control but almost every radio implementation is different. The amount of radio control depends on the particular application and radio.
microHAM © 2010 All rights reserved Disable router queries – When this box checked, Router will not poll the radio for frequency and mode when that information is not available from the communication between the application and radio. NOTE: "Disable router queries" disables Router polling only when the port has been opened by an application program. When the virtual port is closed, Router always polls the radio to support the automatic switching and iLink update functions.
microHAM © 2010 All rights reserved USB transmits data in frames with a delay between frames, Router indicates frame boundaries with three dots (...). When a packet ends with three dots it means that the data continues in the next frame. IMPORTANT: If MK2R is to operate when Router is not running, the settings must be saved as power-up defaults using “Device | Store as Power-Up Settings.” 2nd CAT PORT Beginning with version 7.
microHAM © 2010 All rights reserved FSK & 2nd FSK PORTS The FSK channel is used by the application program to send the FSK keying signal. FSK is used primarily for RTTY. It is very important to understand the difference between FSK and AFSK. FSK is a digital (On/Off) signal used in the transceiver to generate a frequency shift. FSK must be supported by the transceiver (this mode is commonly labeled RTTY or FSK).
microHAM © 2010 All rights reserved Strict bps: Some programs rely on the the UART "buffer full" signal for proper PTT timing and drop PTT (unkey) when the UART buffer is empty. Because virtual ports generally have two buffers - one in the USB driver and one in the hardware - the first buffer may empty before all of the data has been transmitted allowing the PTT to before the message is complete. 'Strict bps' disables the USB buffering and sends one character at a time to the FSK output.
microHAM © 2010 All rights reserved PTT & 2nd PTT PORTS The PTT channels are used to control transmit/receive switching of the transceiver and power amplifier. An internal sequencer assures 100% protection against hot switching of the PA when the PTT channel is used. More information about T/R switching and the sequencer is provided under the PTT tab. Router allows assigning virtual serial ports for PTT using the DTR or RTS signals.
microHAM © 2010 All rights reserved WinKeyer2 WinKeyer2 is the next generation of the unique external CW processor developed by Steve Elliott, K1EL: WinKey with integrated dual radio support. This CW processor supports paddle input like any other electronic keyer, is highly configurable, and converts input received in ACSII (text) format to Morse characters. This unique property assures perfectly timed CW output regardless of operating system load.
microHAM © 2010 All rights reserved CONTROL PORT The Control Port allows an application program (logger) that implements the microHAM Control (SO2R) Protocol to operate MK2R/MK2R+ completely with only a single USB connection. The microHAM SO2R Control protocol allows a logger to specify Transmit Focus, Receive Focus, Stereo/Split headphone as well as control antenna switching and optionally use the CW, FSK and voice memory functions.
microHAM © 2010 All rights reserved CW/PTT steering When manual control of transmit focus is selected in MK2R, CW (including WinKey) and PTT signals will be redirected to the active (selected) radio. This function was implemented to avoid confusion and assure the "expected" behavior. This means that CW and PTT signals for both radios will be directed to the selected (active) radio.
microHAM © 2010 All rights reserved AUDIO SWITCHING TAB MK2R provides extensive and unique flexibility in routing audio among the computer sound card, transceiver, and the station microphone. To understand the way MK2R handles the sound cards, transceiver audio inputs and microphone you must understand how the sound card works.
microHAM © 2010 All rights reserved MK2R allows customizing the audio configuration to meet the needs of a specific logging program and operating style (VOX, foot switch, computer generated transmit/receive switching, etc.) for each mode. In addition, two sound cards (external for MK2R or internal for MK2R+) - one for CW and voice (USB Voice CODEC or SC1) and one for digital modes (USB Audio CODEC or SC2) are selected automatically based on radio mode and user preferences.
microHAM © 2010 All rights reserved When the RADIO1 and RADIO2 buttons are pressed simultaneously, the AUTO light will illuminate and MK2R will switch to the AUTO switching mode. The AUTO mode recognizes five (5) states: ● ● ● ● ● RADIO1=RX & RADIO2=RX & RX focus=R1 RADIO1=RX & RADIO2=RX & RX focus=R2 RADIO1=TX & RADIO2=RX RADIO1=RX & RADIO2=TX RADIO1=TX & RADIO2=TX Receive audio (headphone) switching can be programmed separately for each of these states.
microHAM © 2010 All rights reserved 1. Transmit by VOX or software (CAT) command. This setting is displayed in the TOP picture and indicated by the first letter of the settings (ABCm). The current operating state is indicated by a large black frame around the switching scheme picture. A: Computer audio is disconnected from the radio and the station microphone is connected directly to the transceiver microphone jack. This setting is for those who prefer VOX operation in SSB.
microHAM © 2010 All rights reserved 3. Transmit by foot switch or hand mic PTT. This setting is displayed in the BOTTOM picture and indicated by the third letter of the settings (ACmA). The current operating state is indicated by a large black frame around the switching picture. A: Computer audio is disconnected from the radio and the microphone is connected directly to the transceiver microphone jack. This setting allows the operator to interrupt a DVK message.
microHAM © 2010 All rights reserved NOTE: Use “Select by frequency” only if your radio does not have a dedicated mode (PKT, DIG, DATA or USB-D/LSB-D etc.) for audio based digital modes like PSK31, MFSK, OLIVIA, FSK-RTTY etc. and you must use USB/LSB/FM for digital operation. Use VOICE settings: VOICE settings will be used when LSB, USB, AM or FM are selected regardless of operating frequency. This should be used with most Yaesu transceivers, Icom transceivers that support USB-D and LSB-D and the K3.
microHAM © 2010 All rights reserved FSK/DIGITAL (BBB) – The station microphone is disconnected and the computer generated audio is applied to the radio’s rear panel audio input. This setting is recommended for all digital mode operation regardless of keying type (FSK or AFSK). FSK/DIGITAL (CCC) – The computer generated audio is connected to connected to the radio front panel mic jack and the sound card microphone input is muted.
microHAM © 2010 All rights reserved AUDIO MIXER TAB NOTE: The Audio Mixer Tab is not present in Windows Vista or 7 due to operating system limitations. Windows Vista and 7 take exclusive control of the sound card and do not allow any application to control the overall level or the select/mute switches for any audio "endpoint" (input or output). The Windows 2000 and Windows XP Hardware Abstraction Layer (HAL) that the Audio Mixer tab requires is not present in Vista and Windows 7.
microHAM © 2010 All rights reserved Channel assignments for SC2 (Digital): TX DIGITAL – Select Wave channel RX RECORDING/DIGITAL – Select Line In If these selections are not available, you may need to replace the sound card (or select another sound card in your system). NOTE: Because Windows can reassign sound cards while in use, Router may not invoke the proper mixer. To check that the proper mixer has been assigned, click the Get ID button and confirm that the proper sound card is selected.
microHAM © 2010 All rights reserved If you need to adjust the transceiver drive level during operation you can use the front panel controls and leave the settings in the Audio Mixer untouched. Knob TX1 (11) adjusts the drive for RADIO1, knob TX2 (14) adjusts the drive for RADIO2. MK2R+ allows you to take advantage of a feature of the the USB Voice CODEC to adjust transmit audio equalization. Click on the TX Mixer button, select Options and enable Advanced Controls.
microHAM © 2010 All rights reserved Some tips from Geoff Anderson, G3NPA: TIP: If you have achieved the correct settings for the transmit levels, you will see that changing from the PSK tuning tone to typing text, will make the transmitter power swing from 50% (no typing) to 100% (typing or tuning-tone) as observed on an RMS or average reading meter. This change in power is correct. If you do NOT see a 50% (or more) change, you are probably overdriving the radio.
microHAM © 2010 All rights reserved PTT TAB The PTT tab provides independent PTT configurations for each radio. PTT INPUTS MK2R has ten PTT sources: ● PTT generated by the logging program on the virtual COM port RTS or DTR ● 2nd PTT generated by a second application on the virtual COM port RTS or DTR ● PTT generated on the DTR line of the FSK channel if the PTT box is checked. ● PTT generated on the DTR line of the 2nd FSK channel if the PTT box is checked.
microHAM © 2010 All rights reserved PTT OUTPUTS MK2R has four (4) PTT outputs for each radio: PTT1, PTT2, PAPTT and LNA PTT. PTT1 and PTT2 are brought out to the DB37 Radio connector. PAPTT and LNA PTT are RCA jacks for connecting to external devices. PTT1 is wired to the radio microphone jack and is normally used to switch the radio into transmit in VOICE and CW mode. PTT2 is wired to the radio Accessory jack and is used to switch the radio into transmit in DIGITAL and FSK modes.
microHAM © 2010 All rights reserved PTT lead: Specifies lead-in delay. In CW with PTT1, PTT2 or Semi Break-in, PTT lead is the time between activation of PTT1, PTT2, PA PTT and LNA PTT and the first CW output. Transceiver PTT (PTT1/PTT2), PA PTT and LNA PTT all activate at the same time. In CW with QSK, PTT lead has no effect. The leading edge of PA PTT and LNA PTT are coincident with the CW output. In VOICE and FSK/DIGITAL, PA PTT and LNA PTT lead transceiver PTT (PTT1 or PTT2) by the amount of PTT lead.
microHAM © 2010 All rights reserved FOOT SWITCH SEQUENCER Additional functions can be associated with the foot switch (or hand mic PTT). MK2R recognizes when the foot switch is closed (pressed) or open (released). MK2R can mute or block serial port CW, FSK, PTT and audio when the foot switch is activated. Each of those inputs can be selectively restored when the foot switch (or hand mic PTT) is released or can remain muted until all PTT inputs are released.
microHAM © 2010 All rights reserved CW/WinKey TAB This tab provides the configuration for the internal, WinKey2 based, CW keyer. A complete WinKey2 manual can be downloaded from: http://k1el.tripod.com/files/WinkeyUSBman.pdf. Thanks to Steve Elliott, K1EL for this great product. WinKey2 can be controlled by a logging program or operate in stand alone mode controlled by Router. Router controls the speed range, Paddle mode and other timing characteristics of Winkey2.
microHAM © 2010 All rights reserved CW MESSAGES TAB On this tab you can define nine CW messages of up to 50 characters each which are stored in EEPROM. Each memory may have a programmable repeat delay and/or call another memory. Commands which may be included in a memory are: Merge: Cancel WPM: Set WPM: Set Key: Set Wait: merge two characters without a letter space – [M]AS will sound AS .-... restore speed set by the Speed pot. force speed to the selected value regardless of position of speed knob.
microHAM © 2010 All rights reserved FSK MESSAGES TAB On this tab you can define nine FSK messages of up to 50 characters each which are stored in EEPROM. Each memory may have a programmable repeat delay and/or call another memory.
microHAM © 2010 All rights reserved DVK TAB MK2R allows recording and playing nine voice messages per bank and an unlimited number of banks (limited only by the capacity of the computer hard disk). Banks can be managed with Rename, Add and Remove buttons. Rename to rename the current bank, Add to create a new bank, and Remove to delete the current bank. Bank selection is provided by Bank box.
microHAM © 2010 All rights reserved KEYBOARD TAB The Keyboard Tab controls the operation of a PS/2 keyboard or numeric keypad connected to the PS/2 jack. It is also possible to define control functions for the numeric keypad. Custom controls are invoked by pressing and holding the asterisk key (*) with Numkey0-9. General: QWERTZ layout – configures the keyboard for a QWERTZ layout. FSK from keyboard: Diddle LETTERS: send the LETTERS character whenever there is nothing in the transmit buffer.
microHAM © 2010 All rights reserved SO2R TAB The SO2R Tab is used to configure the signals each program uses to convey transmit Focus, Receive Focus and Stereo (Split) headphone states to MK2R/MK2R+. Computer AUTO Control: If MK2R is in AUTO TX Focus and AUTO RX Focus, radio selection is under software control.
microHAM © 2010 All rights reserved LPT Control of DVK: Used for external control of MK2R DVK from the LPT port.
microHAM © 2010 All rights reserved MODE MK2R includes "special" operating rules selected by the MK2R MODE button. There are three (3) slots, each of which can carry a different operating rule. So far there are seven predefined rules. Additional rules can be added by user request. Use simple auto mode: does not use advanced headphone audio combinations.
microHAM © 2010 All rights reserved ACCESSORY (ACC) TAB The Accessory connector supports 29 I/O functions which can be assigned to six "ports." The left half of the Accessory tab is for RADIO1 (pins 4-9) - the right half for RADIO2 (pins 2,3 and 10-13). Pins 2, 3, 4, 5 are fully configurable and provide radio specific and global functions. Pins 6-9 and 10-13 are programmed as a group.
microHAM © 2010 All rights reserved • RADIO 1/RADIO2 ENABLE Enable signal from MK2R to Radio1/Radio2 – delays generation of RF by radios equipped to use the signal and provides “hot switch” free operation even with VOX or CAT T/R switching • RADIO 1/RADIO2 INHIBIT IN An external Inhibit input for devices such as Power Amplifiers that generate a “not ready” signal. MK2R to delay the PTT1/PTT2 and Enable outputs until the external device signals it is ready.
microHAM © 2010 All rights reserved Serial Port 1/Serial Port 2: When configured for serial device support, each serial port can operate in one of two modes (each mode requires the proper external hardware interface): CI-V: When the serial device function is set to CI-V, MK2R simulates Icom's CI-V transceive function and broadcasts the chosen frequency in Icom format even when the radio is not an Icom transceiver. The CI-V address and baud rate of simulated radio is set in appropriate field.
microHAM © 2010 All rights reserved FUNCTIONS TAB The Functions Tab provides a tool for managing the operating modes and defining the audio configuration in each of the eight states. Configuration data can be uploaded to MK2R and saved as a function or it can be saved to an file on the computer. Any single function or all eight functions can be retrieved from MK2R, saved on the computer and modified. New or modified configurations can be saved, uploaded to MK2R and/or shared with other users.
microHAM © 2010 All rights reserved These RECORDING/DIGITAL states are available: RX focus on R1: RX focus on R2: RADIO1 is selected (has RX Focus) RADIO2 is selected (has RX Focus) NOTE: Split/Stereo is ignored for Recording/Digital Functions stored in MK2R can be saved to and restored from a file. configurations by exchanging files. Users can share The control buttons are: Get: Get All: retrieve the selected Function from MK2R. retrieve all stored Functions from MK2R.
microHAM © 2010 All rights reserved 6 - MK2R OPERATION Setting Audio Levels For optimum operation of MK2R and MK2R+, the audio levels must be set properly. The function of each control was described in the AUDIO MIXER and DVK sections of the manual. About microphones and MK2R: In order to configure MK2R correctly, it is absolutely necessary to understand the difference between electret and dynamic microphones. A dynamic microphone consists of a small moving coil and a magnet.
microHAM © 2010 All rights reserved 4. If you are not using Icom radios, turn the RADIO1 and RADIO2 preamplifiers OFF and turn the RECORDING-LIVE MIC preamplifier ON. Use a dynamic microphone, there is no bias for an electret mic. 5. If you mix one Icom and one non Icom radio, you must use a dynamic microphone and take care to prevent the Icom DC bias from reaching the microphone.
microHAM © 2010 All rights reserved Setting audio levels in Windows 2000 and Windows XP: (If you are using Vista or Windows 7, skip to Page 69) . 1. Open Router's Audio Switching tab and set the VOICE switching to CmCmA, Voice codec, SC1 on the Radio 1 tab AND Radio 2 tab. 2. Go to Audio Mixer tab and confirm that the correct sound cards are selected ● For MK2R+ choose USB Voice CODEC at the left side and USB Audio CODEC at the right side.
microHAM © 2010 All rights reserved 14. On the DVK tab, select default bank, set the REC MIC, TX MASTER and TX WAVE levels to the same position as you set on the Audio Mixer tab. 15. Press the "Record" button and adjust the recording level with the REC MIC level so that signal does not peak into to the red area. 16. Select Radio 1 17. Press the "Play" button and check that the drive level to Radio 1 is same as you set in the previous steps. If not, adjust the R1 WAVE level. 18. Select Radio 2 19.
microHAM © 2010 All rights reserved Setting audio levels in Vista and Windows 7: 1. Open Router's Audio Switching tab and set the VOICE switching to CmCmA, Voice codec, SC1 on the Radio 1 tab AND Radio 2 tab. 2. Click the "Sound Card" button. 3. On the "Audio Devices" window: ● For MK2R+ choose "Speakers (USB Voice CODEC)" in the Mixer and WaveOut boxes. ● For MK2R select the sound card connected to the SC1 jacks in the Mixer and WaveOut.
microHAM © 2010 All rights reserved 14. Select Radio 2 (press the Radio 2 Transmit Focus button). 15. Turn on VOX and speak into the microphone. Using the R2 trimmer, set the same drive level as you set in step 17 on page 66 - do not adjust the MIC GAIN on the radio. 16. If you cannot balance the direct and sound card levels with the trimmer, return it to the midpoint and click on "Balance" in the "Speakers (USB Voice CODEC)" Levels tab and adjust the Right level. Then use the trimmer for fine adjustment.
microHAM © 2010 All rights reserved Understanding Transmit (TX) Focus MK2R allows changing transmit focus several ways. The READY lights indicate which radio will transmit in response to a PTT signal. Manual TX focus mode In manual mode, focus (selecting which radio will transmit) is fully under operator control - the computer CAN NOT change focus. The operator can select the active radio (change focus) by pressing the RADIO1 (B14) or RADIO2 (B15) buttons.
microHAM © 2010 All rights reserved Understanding Headphone Switching Like transmit focus, headphone switching (receive focus) can operate in MANUAL or AUTO modes. Manual headphone switching In manual mode the operator has several ways to control what he hears in the headphones. There are “small preset” buttons RADIO1 (B7), BOTH (B8) and RADIO2 (B9) as well as the “full access” LEFT EAR (B4), RIGHT EAR (B6) and “shift” + (B5) buttons.
microHAM © 2010 All rights reserved TIP: To confirm that your logging program, digital program, or DVK is sending audio to the radio, you can temporary monitor the output of the transmit sound card in the headphones by holding the “+” button and pressing the appropriate RADIO button. While you hold this combination, you will hear the transmit audio in both headphones. AUTO headphone switching Automatic headphone switching is a unique and powerful feature of the MK2R.
microHAM © 2010 All rights reserved Using Functions Functions are memories in which the current configuration of MK2R, including all headphone selections, can be stored. Using these functions (memories), the operator can easily program and recall the MK2R configuration for specific operating situations – for example: a small pile-up with multiplier hunting on the second radio, a large pile-up, S&P on both radios, 40 meter split operation, etc.
microHAM © 2010 All rights reserved Understanding Interlocks MK2R provides several forms of interlock and timing protection. When a radio is locked, MK2R immediately disables any input to the "locked" radio which could cause it to generate RF (microphone, sound card output, CW, PTT1, PTT2, and PAPTT). The inputs remain disabled as long as the condition that generated the lock continues.
microHAM © 2010 All rights reserved ENABLE: When a pin is configured as enable (inhibit output), it can be connected to the transceiver inhibit or enable ("LINEAR") input with the proper driver to assure completely safe, hot switch free operation even if the transceiver is operated in VOX or is switched to transmit by CAT command. MK2R automatically generates an ENABLE signal after the PTT lead defined on the the PTT tab.
microHAM © 2010 All rights reserved EXTERNAL KEYBOARD/KEYPAD NOTE: The keyboard/Keypad must be PS/2. A USB device with PS/2 adapter will not work properly. MK2R includes the ability to generate FSK or CW, record and play CW, FSK or VOICE messages using a PS/2 keyboard or numeric keypad connected to the PS/2 jack. A numeric key pad is sufficient to record and play CW and DVK messages, control CW speed (WPM) or play a serial number message. “Live” CW or FSK (RTTY) requires a full keyboard.

microHAM © 2010 All rights reserved APPENDIX B – microHAM Control Protocol Introduction This appendix describes the commands in the microHAM Control Protocol that are likely to be useful to users in creating custom macros in loggers that support user defined “scenarios.” These user level commands can be used to select antenna outputs (e.g.
microHAM © 2010 All rights reserved ● ACC output control: These commands control 16 bits represented by the 4-bit outputs of the ACC port. The 4-bit outputs must be configured for “Protocol Control” on the ACC tab. Current firmware treats the 4 four bits as a HEX representation (0-F) of a 1:16 decoder connected to the port. Only one output may be active. This command sets the output using a binary mask.
microHAM © 2010 All rights reserved APPENDIX C – RFI Considerations A few guidelines to eliminate problems caused by RFI: 1. Proper grounding of all electronic equipment is critical. A modern station contains many, diverse, types of interconnected and interrelated equipment: transceiver, power amplifier, computer, control boxes, switch boxes, and power supplies. Each of these must be individually grounded with a separate connection to a single common ground point, thus forming a star ground connection.
microHAM © 2010 All rights reserved APPENDIX D – Tracking NOTE: Tracking is experimental code started in Router 7.5.0 for linking the transceiver frequency to a tracking receiver. Mode linking and bidirectional frequency tracking are not currently supported. microHAM will be expanding features and adding support for additional radios in the future. The initial version has been tested with Perseus SDR only.
