you have shorted somethig on the circuit board. my advice to you is to carry it to a cb shop and let professionals solve your problem, a cb shop will have the proper equipment to diagnose and fix the problem. with what you described this problem is probably a little more complex than you will be able to fix yourself.

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.

Sounds like you have lost a final or a driver transistor if so a shop or reputable repairman is your best answer. You should also have him check your cables and SWR on your antenna system as well as check for loose grounds. Sounds like you had a high SWR and blew out a final transistor. But it could be as simple as a loose component or cold solder joint in the radio. Get professional help.

SOURCE: galaxy dx 2517 frequency drifts sometimes on
The mixer crystal is unstable. It may need replacing. Some times you can reset them. Take a soldering iron and heat up the mixer crystal up for about 5-7 seconds. See if this stabilizes it. If the radio still drifts,then you need to replace the mixer crystal.
