Ft 2900r when I push then talk button on mic it shows error on all channels even with second mic


Sounds like a programming error. Does it work properly in VFO mode? Did you try a reset?

Ft 2900r yaesu all i see on the screen is B0001 i can't see the frequency


Try powering the unit up while holding the Set/MHz button. I did that and it restored the display (and the rest of the radio's operation) back to normal.

The character codes are test-mode displays that correspond to frequencies (in MHz):

A0001-A0640 - 136.000-143.9875 in 12.5 KHz steps B0001-B0400 - 144.000-147.990 in 10.0 KHz steps
C0001-C2081 - 148.000-174.000 in 12.5 KHz steps

I haven't the foggiest idea why this isn't in the manual somewhere, or at least flipped back to normal by a two-key or three-key reset. 73, k2mct

Rci 2990 won't keyup


If on all modes check the mic first to see if wired right or wires broken--this should have am-fm-lsb-usb---which works or do not work.

88, hi- the problem your describing depends on whether the red keyup light stays on while it's breaking up. I'll give you some possibilities to check as all of these could cause what your describing.
1- A broken audio wire in the mic cord.
2- Dirty mic switch.
3- The mic jack starting to come loose/or has rotated.
4- Circuit board ground screws starting to come loose.
5- Make sure all coax and jumpers are screwed on tight.
Thats about all I can think of right now, one of these is causing your problem.
Hope this helps you out, let us know,, Mechanic
