Any easy way to check if it's the mic instead of the radio itself?


Just find someone with a VHF marine walkie talkie. Don't use Ch 16.

I keep one of these inexpensive meters in the antenna line of each VHF so
I can SEE it's putting out that distress call, RF wise.

PWR tells you its transmitting. Switch to FWD and turn the knob until
it's full scale "SET", switch to REF and read the SWR, telling you what
the antenna and coax condition is. No reflected power 1:1 is perfect but
rarely attainable. Any SWR below 2:1 is fine.... The meter is self
powered from the RF, itself. Just feed the RF power through it on its
way to the antenna. This is 90% of radio troubles...No RF or bad
antenna.

But, But, Larry, the above only proves that the unit is radiating RF,
NOT that it is capable of actually modulating voice on that RF.....
The HandiTalkie will tell him if the unit is actually modulating
voice, but, REALLY, he needs to get the whole radio over to a
"Good" Radio Tech, with good instrumentation, and get the system
check out.....

Bruce in alaska you get what you PAY for......
