Cobra 142GTL

I was just wandering if anyone knows whether or not the Meter is suppose to reflect modulation on SSB like it does on AM or not. My meter on m y 142 works fine on AM, But when I tx on SSB it stays flat on the tx but works normal on RX.

no, the mod. meter works just on am. I used to have one that got a virgin in excellent shape and I asked the same question to my tech. I imagine the meter would need a carrier to measure modulation from, thats probably why she does nothing on ssb.

it depends which meter you are referring to.

the meter on the left is your S-meter and also your TX power meter.
this one should show a carrier when TXing on AM, and should move upward a bit while talking into the mic.

on SSB this one should sit at 0 when the mic is keyed until you talk into the mic, then the needle should move to the right corresponding with your speech.
"bouncing around" as you talk.


now, the meter on the right is your modulation/ SWR meter.

it will only move on AM when in the MOD position.
it will not move on SSB. (maybe a tiny, tiny bit, but not enough to notice)
in the SWR position, it will read your SWR in the AM mode, but will not be accurate when in SSB mode.
the meter on the right really does nothing when you are in SSB mode.

best of luck,

And loose has sum that up as good as it could possibly be done.
