Odd Cobra 29 Question

yep take it to a shop they will figure it out might be something with a ground or even in the mic its something new to me maybe even the switch

 

SEND IT TO COBRA !

See if you need a RMA with ICOM here at our shop we have to do that

 

Sounds like something in that switch is shorting out. A defect for sure

 

Let us know how it works out !

 

I just now got in from a field trip at a repeater site and read this whole thread. Sounds like two things are goofy; one will be determined by Cobra, but it sounds like something is fouled in the wiring to the meter function switch.
Also, unless you've got a loading coil somewhere after the coax terminates at the antenna, there's no way a 4.5 ft steel whip should be able to be made to be resonant on CB frequencies. It's closer to 6 Meters, which is an even harmonic of the CB freqs, and the impedance should be horrendous.
I'll be in the line of folks waiting to hear what Cobra says. At least it'll be more satisfying than just swapping it out at the dealer, cuz then we'd never know what was going on.
The mind boggles!

P.S. Nice thing about Icom is that it doesn't often have to go back

 

We have 1500+ we matain here they are all over 5 years old in a JAIL so they get abused ... Many have NEVER been through the shop MOST that have are for mike jack failures ..... about 40 out of 1500 over 5 years.
These are F43's the F4's did as well when we retired them with 11 years service 90% were still working ...... Not bad for a $400 HT .......

 

Many new radios are not easy to fix so they swap them out ......
