- FT736R.2
-
- I bought a Yaesu FT736 about 6 months ago. It's a great radio but one
- thing annoyed me about it. When I used in on FO-20 or the microsats with my
- TAPR PSK modem, the PSK modem adjusts to the doppler frequency shift by sending
- pulses to the up/down buttons on the microphone. Only problem is, everytime it
- sent a pulse the radio went BEEP. This beep didn't come thru the speaker,
- instead it was emitted from a separate buzzer. As a result, even when using
- the headphomes, the beep would disturb the whole house. This was a particular
- problem on late night passes. Thanks to a suggestion from WB2IBO and the folks
- at Yaesu, I've discovered you can fix the problem.
-
- If you remove the top cover you will find a circuit board right behind the
- front panel. As you are facing the front of the radio on the top left corner
- you will see capacitor C63 identified on the board with a red wire going into
- the circuit board next to it. Clip the red wire and no more beep. You won't
- actually see the beeper. To find the beeper you have to remove the top and
- bottom covers (see the manual) and then loosen the screws on either side of
- the front panel (see section 3.5.4 in the manual). At the bottom left of the
- circuit board is the black buzzer, about the size of a quarter. The red wire
- you need to clip starts from here. You don't actually have to remove the
- bottom cover if you clip it where it goes back into the circuit board on the
- top, however.
-
- You could rig up a switch to turn the buzzer off and on, but I don't why
- anyone would ever want to turn it back on. 73 de WA0PTV @WA0PTV
