since this is a fairly new radio, your only resource is your manual and schematic.
As a Ham you should be able to read them. If you are thinking of installing an aftermarket mic, you don't do this on most ham radios, they are not CBs that you can put a "power mic" on. too much audio input on an FM transceiver can make your transmission unintelligible
Turn the squelch until you hear noise, then back off. Also, make sure you have a "+" and not a "-" by your group number as it will lock out channels that don't have a matching PL tone (CT). Make sure your group is set to FM and not MOT, or AM.
Helo there: if the radio is working just go to yahoo and search for this : police scanner frequencies then just look for your area and enter the numbers and you will be able to hear local stations ok? best regards michael
Since you didn't say if you have ever used this radio successfully before, I have to assume it is "new to you" and that you have never seen it work or used one like it before. Start with a few basic settings below:
Turn Squelch to minimum. Set RF Gain (if present) to maximum Set Mode to AM or FM Set volume to 1/3 up Connect to 50 ohm dummy load.
Turn power on. Hopefully you hear static. If not, try SSB or FM. Still nothing? Try connecting to an external speaker.
Chnage back to AM or FM mode. Key mic check & for transmit indicator. If none, change mic or manually short the PTT contacts in the mic or at the radio to see if it can be made to xmit.
If no xmit - insert SWR meter between xmitter and dummy load. Try to xmit on AM or FM again while watching SWR forward power, if none indicated, xmitter is probably defective.
Replacing parts in a xmitter is not recommended. You'll need an FCC license and a fair amount of expensive test equipment to test repairs, set power levels and deviation and perform an alignment to be sure you aren't causing interference on other frequencies and bands.
You'd be better off bringing it to a radio repair shop for repairs and an alignment.
