1 General information (setting up microHAM and N1MM logger) In this document information is gathered about setting up the freeware contest program N1MM logger with the microHAM MK2R+ SO2R controller and Station Master banddecoder. The original text from Joe, W4TV has been used as a start for this document and updated with texts from Pete, N4ZR his SO2R−only document. Also information from the N1MM and microHAM reflector are used and of course own trial and error. This document has multiple sections.
1.2 MK2R+ 1.2.1 Proposed Virtual Port numbers Note: The absolute port numbers do not matter. The key is consistency − the same port number must be used for a specific function every time it is used. The port numbers below will be used (as proposed by Joe, W4TV).
select the wrong input unless USB Voice CODEC is the Windows Default sound device (bad idea) because of issues with the non−standard RealTek driver. Finally, MK2R+ MUST be in VOICE mode and the audio switching must be correct so that the microphone is switched to the sound card when you are recording ... there are three possibilities depending on whether you are trying to record on air or not and whether the logger activates PTT.
For Windows 2000 or Windows XP. right click on the Speaker Icon on the task bar and select "Adjust Audio Properties" or open "Sounds and Audio Devices" in Control Panel and reset the Default device for Sound Playback and Sound Recording to your computer's primary sound device. For Windows Vista, 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.

FSK or CW messages PTT ON/OFF is not supported as an embedded command in the MK2R. Use the F10 key from the PS/2 keyboard. RF problems with my MK2R The bypass modification for the microKEYER II has not been evaluated for the MK2R+. However, due to the layout it will not be as simple as the microKEYER II version.
higher and there will be a substantial voltage "kick" on when the relays. The relays in the Station Master won't handle the currents required by the Tailtwister, so it was necessary to use some SPDT power relays with 20A contacts and 12V coils that I obtained at a local electronics surplus outlet to buffer the Station Master relays. The power relay NO contacts were simply wired across the CW, CCW and Brake switches in the Tailtwister control box.
No audio on line in CAT noise : Buzzing sort of doo doot sound in the background of the record This is CAT polling noise. The K3 has RF chokes in the ground leads of the RS−232 port, the ACC port and the mic return. This results in common mode noise if the ground ring of the Foster mic connector is not tight and the KIO3 board is not seated properly. The polling noise is particularly significant if the rear panel (3.
microphones as they generally run much higher "mic gain" levels which increases sensitivity at the line in. 1.10 Realtek sound card drivers and MK2R+'s USB Voice CODEC 1.10.1 One soundcards installed (only Realtek) This screenshot file explains how to get around a problem caused by some Realtek sound card drivers (used for Realtek and some Soundmax cards and onboard audio components) when trying to use the MK2R+'s USB Voice CODEC.
Click on the Audio tab first. Set the USB Voice CODEC as the Default device for BOTH playback and Recording, and click Apply, then OK out. Now click the Sounds tab. Normally, the Sound scheme will be identified as Windows Default, but if you leave it alone, the Windows sounds (like the File not found "clunk", for example) may wind up in your recordings or even go out over the air. To prevent that, you need to create a new scheme.
1.10.4 Two soundcards installed (disable Realtek and use the other..) The issue with the RealTek HD Audio system is that RealTek creates two separate mixers: RealTek HD Audio Input and RealTek HD Audio Output. Windows assigns the Audio Output as Mixer 0 (Windows Default) and Audio Input as Mixer 1. This results in a mismatch between the Wave In ID, Wave Out ID and Mixer ID for not only other soundcards but also the Wave Out device.

This setup is for use at the station PA1M and for the hardware and software I use. NB. This is a work in progress. 73' Thomas (pa1m@veron.nl) Latest update: February 13, 2009 Back to menu. NB.

The antenna switch requires 12V to select an antenna (common ground). Controlled by Port A configured as voltage sourcing using internal power (default INT/SRC jumpers). (outputs A1−A10). Outputs A6−A10 are not used (yet).

Normaly gets GND thru 1kohm resistor (TX enabled).
The schematic above represents a partial schematic (only antennas 1 and 2) and not that the "Inhibit" connections are to "Key In" on the PA port. The intent is to avoid using B7−B10 and to lockout transmit only on the 'second' radio. Remember only the application software can prevent selecting an already used antenna port − this simply prevents transmitting into an open feedline. Using the situation of triband antennas on ports 1 and 2, the above circuit will prevent transmitting into an open port.

The N1MM Logger audio control cannot handle the situation where the Wave ID <> Mixer ID − it will send (or record as the case may be) audio from the wrong sound card.

Tab: SO2R Select microHAM control protocol on COM port (NB com port is set on Ports tab) and 1 footswitch for both radios. TX logic: First one wins ... is the correct logic for SO2R. It prevents transmission from starting on the second radio if the first radio is already transmitting. These settings allow N1MM Logger to fully control both transmit and receive selection automatically. Stereo receive is commanded by the ` (backquote or unshifted tilde key) or the {STEREOON} and {STEREOOFF} macros.

Select Controlled by microHAM control protocol in the two drop−down boxes. Pins 6−9 and 10−13 are connected to two banddecoders which drive the microHAM 2by10 SO2R switch. Note that these precisely pass through the antenna selections from the N1MM Logger Antenna tab − so you can have multiple antennas on a given band, selectable from the keyboard.
By Joe, W4TV: Using the "Functions" tab in Router, create the desired audio switching pattern. Check the Auto boxes for Transmit Focus, and Headphone Switching as well as Latch and Monitor. From what you describe it would look something like this: LEFT RIGHT ABLRABABLRAB RX on R1 X X RX on R2 X X C on R1 X X C on R2 X X TX on R1 X X TX on R2 X X STEREO X X X X Select a "Function" memory to store this configuration and click the "Store" button to write it to the MK2R.

The "TX on R1/R2" options are only available if "Monitor" is selected. The Stereo selections are an "override" that is applied only if the logging program issues a "Stereo" directive (e.g.

MMTTY RX bandwith exactly matching the RTTY signal. The brickwall DSP filter with sharp skirts cuts everything off but the desired signal. It is clearly seen at the tuning indicator. With such a set up you can even use wide SSB filters and still have pretty nice results overall. Obviously if you use other filters, as well, it makes the overall selectivity even better. Yet another positive aspect of that is the tuning easiness. It comes from the fact that only one and only signal matches the bandwith.

Even when I am using AFSK I operate FSK−style, i.e. doing all my tuning with the radio, never with the mouse − I just watch MMTTY's crossed ellipses and turn the tuning knob to fine−tune. That makes it feasible for me to open the second DI window as an alternate decoder. I have it set to use MMVARI instead of MMTTY, set its decoding frequency on my centre frequency, and use it to give me a second opinion.

Many hams, both old timers and new comers, have gotten RTTY working and made QSOs. Now they are trying RTTY contesting. We, and other RTTY contesters, have noticed that some RTTY new comers are unaware of efficient contest exchanges or have picked up a few bad habits. After each RTTY contest there are email discussions about ineffective (i.e.
Good luck in the RTTY contests! 3.8 Starting in September This first part of the big 3 part CQWW fall contest is coming soon. CQWW RTTY occurs the last weekend in September. It is an excellent chance to test out antennas, radios, amps, and other station changes made over the summer. It is also an excellent way to learn, or brush up on, SO2R or other logging program features since you don't have to concentrate as much on copying the exchanges and calls.
