FSG 2T PS Portable VHF/AM Airband Transceiver Notes: 6 DITTEL D10077 May 2010
FSG 2T PS Portable VHF/AM Airband Transceiver 1 For Your Safety Every radio, when transmitting, radiates energy into the atmosphere that may, under certain conditions, cause the generation of sparks. All users of our portable radios should be aware of the following warning: Do not operate this portable radio in an explosive atmosphere (petroleum fuels, solvents, dust, etc.
FSG 2T PS Portable VHF/AM Airband Transceiver Such a radio is allowed only for the use as ground station! Always turn OFF the radio when installing or removing the unit! Always turn OFF the radio when starting nearby engines or vehicles! The FSG 2T PS should be used exclusively for aviation related communication purposes. Unauthorized modifications and changes of the system are forbidden. Sufficient speech volume is very important.

FSG 2T PS Portable VHF/AM Airband Transceiver 2 General Description 2.1 About this document This operator's manual contains operating instructions for the fixed/ portable/ mobile VHF/AM Airband Transceiver FSG 2T PS of Dittel Messtechnik GmbH, 86899 Landsberg, Germany. 2.2 Application & Description of the FSG 2T PS The portable battery powered VHF/AM Airband Transceiver FSG 2T PS allows independent operation as an airborne or ground radio. Stationary, portable or mobile applications are possible.
FSG 2T PS Portable VHF/AM Airband Transceiver microphones and external power supply, and a built-in loudspeaker. The lock-in type carrying handle completes our robust FSG 2T PS unit. 2.3 Equipment required but not supplied Vertically polarized VHF airband antenna, frequency range minimum 118 to 137 MHz, 50 Ohm, e.g., DITTEL spring steel band antenna, A/N F10345. Dynamic Microphone 30 to 600 Ohm, e.g., WD handheld dynamic microphone with PTT-key, 5-pole DIN plug and coiled cord, A/N F10346.
FSG 2T PS Portable VHF/AM Airband Transceiver 2.5 Re-calibration Information IMPORTANT! For the first time after three years, FSG 2T equipment for ground applications requires checking and re-calibration of the high precision reference frequency (tolerance better than ±10 ppm). For airborne applications, no frequency re-calibration is necessary, since applications in the 25 kHz channel spacing require a frequency accuracy tolerance of less than ± 20 ppm.

FSG 2T PS Portable VHF/AM Airband Transceiver 4 4.1 Operation Introduction This section contains a description of the basic operation procedure for the portable transceiver FSG 2T PS. DANGER! DO NOT OPERATE THIS RADIO IN AN EXPLOSIVE ATMOSPHERE (PETROLEUM FUELS, SOLVENTS, DUST, ETC.). A front view of the FSG 2T PS is given on the last page of this manual. Please fold out the back flap when reading the operation instructions. 4.
FSG 2T PS Portable VHF/AM Airband Transceiver Reference: Approximately +20°C / +68°F, battery 7.2 Ah, only radio is supplied. Duty cycle: 10% Transmit, 20% Receive, 70% STBY Flashing Dc value only ca. 4 hrs left in Transmit: Flashing Dc value also ca. 45 min. left. during Receive: Recommendation: Reduce utmost transmitting! Short-time flashing Dc ca. 45 min. left in Standby.
FSG 2T PS Portable VHF/AM Airband Transceiver 4.3 Battery Charging To recharge the built-in 7.2 Ah accumulator we recommend our automatic battery charger DL-50A. Charging should be done within the ambient temperature range of +10°C to +40°C. The charger DL-50A is designed for connecting to 115 Vac or 230 Vac, 50 to 60 Hz mains. For operation, check that the unit's operating voltage is identical with your local mains supply.

FSG 2T PS Portable VHF/AM Airband Transceiver 4.6 Turning ON - Selecting Frequency - Audio Volume CAUTION! The FSG 2T PS should be turned ON after engine start-up. This is a simple precaution which helps to protect the solid state circuitry and extends the operating life of your avionics equipment. IMPORTANT! Frequent transmissions as well as large receiving volume reduce the operating time when radio is only powered by the built-in battery! Turn the radio FSG 2T ON by rotating the VOL knob 1 clockwise.
FSG 2T PS Portable VHF/AM Airband Transceiver etc.) with rollover at each MHz and band edge (121.97 or 121.00 121.97). 122.00 This is the new active frequency! Example: CHANNEL MODE or CH ONLY: Important: The appropriate operating frequency must be stored already in a memory channel (refer to § 4.9 Memory Programming). Select appropriate channel memory number together with the associated frequency by rotating the F/CH knob 6 . A clockwise rotation will increment (4, 5, 6 etc.
FSG 2T PS Portable VHF/AM Airband Transceiver 4.7 Receive (Listen) Operation After turning the radio ON the automatic squelch is either ON or OFF depending on SQ knob 2 position. Squelch ON means that without recei noise is blocked, the TX/RX LED 4 is clear. When normal signals are received, the TX/RX LED 4 turns to green; weak signals and interfering pulses are disabled. Set the RX volume of the built-in loudspeaker 9 or earphone to a comfortable level by rotating the VOL knob 1 .
FSG 2T PS Portable VHF/AM Airband Transceiver 4.8 Transmit (Talk) Operation WARNING! Every radio, when transmitting, radiates energy into the atmosphere, therefore: DO NOT operate this portable radio in an explosive atmosphere (petroleum fuels, solvents, dust, etc.)! Risk due to generation of sparks! DO NOT transmit with the spring steel band antenna inside aircraft or vehicle.
FSG 2T PS Portable VHF/AM Airband Transceiver IMPORTANT! The radio is equipped with a transmit TOT time out timer. This is used to limit the duration of transmissions to approximately 2 minutes. When the transmitter is keyed continuously longer than 2 minutes the display of the FSG 2T starts flashing and transmission is disabled. Although the display is flashing receiving on the displayed frequency is possible! If you have to make calls longer than 2 minutes, momentarily release the PTT key and press again.
FSG 2T PS Portable VHF/AM Airband Transceiver 4.9 Memory Programming IMPORTANT! Memory programming is disabled for all FSG 2T radios which are marked CH ONLY! Memory programming is disabled at a supply voltage below 11 Vdc. When storing a frequency into a memory the "old" frequency will be overwritten without warning! Up to 20 non-volatile memories can be user-programmed. They are accessible after calling up the respective CHANNEL MODE. 4.9.
FSG 2T PS Portable VHF/AM Airband Transceiver 4.9.2 Programming while in the CHANNEL MODE: IMPORTANT! While in the CHANNEL MODE only pre-programmed Channel Numbers with its corresponding frequencies can be stored in other memory locations! Example: Turn the F/CH knob 6 to change the underscored Channel Number to the desired Channel Number to be stored in another memory location. Press the STO button 3 once to initialize storing. Release the STO button 3 . A flashing "CH" is shown.
FSG 2T PS Portable VHF/AM Airband Transceiver 4.10 Lighting the Frequency Display and Front Panel Lighting of the frequency display 7 and front panel is activated by pressing the red test button of the battery indicator 11 . 4.11 Turning OFF the radio Always turn OFF the radio after use by rotating the VOL switch 1 to the fully ccw position to prevent unnecessary discharge of the battery. During standby or carrying, the handheld microphone (A/N F10346) can be hung onto the right flange of the case. 4.
FSG 2T PS Portable VHF/AM Airband Transceiver 4.14 Battery Operating Times The following duty cycle of Transmit (TX), Receive (RX) and Standby (STBY) results in available operating time (hours). Both the worst and the most favorable operation conditions are considered, e.g. maximum receiver volume combined with maximum speaker load. Higher current consumption will degrade the nominally available battery capability, as well as lower temperatures.
FSG 2T PS Portable VHF/AM Airband Transceiver 4.16 Siting The portable radio FSG 2T PS operates in the VHF frequency band, this is a Line-Of-Sight (LOS) frequency; therefore, siting of the radio greatly affects its operating range. The longest range is normally obtained when a direct LOS is maintained between the radios. Use of hilltop, roof or tower locations will increase the LOS range.
