I see no one has responded to your question. The reason may be that the information is a bit vague. The are a lot of reasons a radio won't receive. In the Galaxy 99, the mic doesn't have to be connected to receive a signal so that illimates the mic possibilities. I have found that in some of the Galaxys I have worked on, that the if section ( thats the section near the pll chip, has cold solder joints ( broken solder connections to the pc board ). You may want to look real close at the pc side of the board with a magnifing glass and see if you can find any electronic components ( resistors, transistors. etc ) loose. Good Luck

Based on your post of no transmit, a couple of possibilities:
1. defective microphone or cord or PTT switch (the red TX light does not come on when pressed);
2. TX light comes on but no output, defective finals and/or drivers. These are the transistors screwed to the chassis of the radio very near the antenna terminal;
3. defective regulator IC that provides the TX B+;
5. insufficient amperage from you power supply;
6. too high SWR.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
