BULLETIN # 854
MODEL: TR-7730
SUBJECT: Transmitter Freq Response, Voice or DTMF

Operator complaints of insufficient lows in transmit, or faulty Autopatch
operation traceable to incorrect twist (high to low tone group balance) may
be remedied by changing two capacitors at the mic amplifier input.

On the RX/TX unit X44-1450-61, change C78 and C81 from 0.1uf to 1.0uf, 35v
tantalum (CS15E1V010M) to increase low frequency transmitter frequency
response.  Adjust Deviation (VR3) or mic gain (VR2) as necessary.

Installation time for this procedure is 1/2 or less.
