do you have the original archive for the radio? if so it may dump the tuning data back to it. otherwise you need to start over, i believe you can reinitialize the board and it will set everything back to default. you WILL need a service monitor for all tests and a way to inject a 80hz and i believe a 3khz tone for setting the mod levels. about the only things on the RX side you can do is adjust freq(which is the reference oscillator under the tx settings), squelch threshold, and rated audio level. other than if it is off freq, you will not make it any hotter just open the squelch to more noise.
