The TM-D700 A/E has a service mode that lets you adjust many parameters of the radio for both bands. The setup is easy, and the following things can be adjusted: Squelch open sensitivity S meter calibration Transmission output power (adjust at lower limit frequency, center frequency, upper frequency of both bands) Transmission deviation DCS modulation balance Tone deviation DCS deviation To get into the mode, short pins 3 and 6 of the 6 pin data radio terminal. _6___ / O||O \ |O O|3 | OO | \------/ Sorry for the bad drawing, but consider each O a pin on the jack. The center slot for the plastic tab in the connector is on top of this. Pin 6 is on the upper left, pin 3 is on the right middle. With the radio powered off, short these two pins together. Now, hold down the F and the TONE key and turn the power ON. The radio will come up with 144.000 and some data on the right side. The menus will look like they do when you're in the MNU. Use the left and right buttons to change things. Using the <- and -> selections on the menu, you can scroll through the options. According to this spec sheet here, the radio can be set to 60W on 2 meters and 42W on 440. ALL ADJUSTMENTS ARE MADE FOR EACH BAND SEPARATELY. Be sure to do power adjustment into a 50 ohm dummy load! Do not worry if you don't recognize these menu names. Many of them are graphical on the bottom that change with the mode you're in. VFO, MR, ENCODER (the left wheel), MHZ, and BAND SEL (the buttons you push to change bands) all function in this mode. To adjust squelch sensitivity, put the desired signal on the antenna connector and press SET. (menu item on the bottom.) To adjust the S meter, put a signal you want for S1 on the connector and press the S1 button on the bottom. Same goes for S7. Output power is adjusted by selecting FREQ1,2, or 3 which sets different frequencies. Key down the mic and transmit into the dummy load. Turn the encoder left or right to adjust output power. Press LOW to adjust for low, medium, and high power. (make high power 5W and low power 50W, impress your friends!) Transmission deviation is adjusted with the <- and -> buttons. There's a MAX DEV setting if you want to bleed over to adjacant frequencies. (piss off your friends!) Press the SET key to set it. DCS modulation balance is set with <- and -> and by pressing the SET key. Same goes for TONE deviation and DCS deviation.
