Galaxy melaka ssb receives but wont transmit whats the fix

SOURCE: GALAXY 959 CAN TRANSMIT BUT NO RECEIVE

try the external speaker /if that is not working you may need put in a new receiving chip it is on the right side has 10 pins.

SOURCE: GALAXY 88 HIGHT STATIC IN THE RECEIVE ..

Could also be off-frequency.
RX circuit mis-aligned.

(or, as always... snake in radio... worst problem of all :)

DX 2517 and DX 2527-
Symptom:Buzzing or motorboating sound in either the transmit or receive.
Problem: TR602 is oscillating
Cure: Replace C602 with a .01uF cap {Cap is located in the power supply board}.
RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.
