Try a different mic . dimmer on radio may not be working .

as far as the transmit frequency changing while you have the mic keyed this is normal, the transmit frequency is a little different than the receive, as far as the lost channels go you need to check the galaxy website and check to see if thier is any fixes listed. if none is listed then you can send the tech's a e-mail and tell them your problem and they will advise you on what to do.

oh, that's nothing, just a faulty meter, take it to a radio repair store and have them rewire it, happened with my Galaxy DX 2517, just don't try to do it yourself ok. Another thing, you do realize the lower your SWR, the better your radio's perforomance?
SOURCE: When mic is keyed, TX light illuminates but power meter does not
make sure your s/rf switch is in the right place on the radio is the most common problem i have found
SOURCE: channel light wont come on. can not key up or
Hi there!!
It looks like your problem would be your Voltage regulator has either went bad or if your radio is mounted in a truck that vibrates alot then one of the three legs of the Voltage regulator has broke loos from the board. If you do not have experiance in electronics or soldering you should let a Radio Tech. do it for you or you could damage the radio!!! If you choose to do it your self then you must disconect from power then take the covers off of the radio. Turn the radio up side down and look inside the radio you will see the PC board has many compnents inside and beside each one there is a letter and numbers followed by the letter. look to your right and you will see a smaller PC board mounted to the right side with 2 screws to the out side of the chassis. Remove the 2 screws and carfully move the board out of the way so you can see the main PC board. Look down on the right edge of the main PC board and you will see a small black transistor with 3 legs on it the number on the PC board is TR41 when you find it turn the radio over and inspect the 3 legs that are soldered to the PC board and look for a crack or loose solder joint if you find one resolder it or resolder all three legs. If there is indeed a crack or bad solder joint then resoldering it should bring it back to life again!! If not then you may need to replace it with another one!! There is another transistor not to far fron the voltage regulator that may have went bad too it is TR40 that works with the regulator but is unlikely the problem but you never know. Try TR41 first it should fix it for ya. Feel free to E-mail us with any other questions that you may have at: [email protected]
Thanks Dennis

Try replacing TR41 (2SA473).
Also check TR40 (2SC945), D78 (7.5 volt Zener Diode), and D79 (KB 262).
