I have a Cobra 29 .

The problem is it shows no output watts on the watt meter, or on the radios meter.

When you key up the mic in SWR/CAL it will not move the needle on the radio.

All so if the CB is in SRF mode it will not move the needle on the external watt meter.

I can here myself through the Talk back.

I put a scope on the Final and the driver and I see RF on both.

I all so checked the final (2078) with my DVM and it checked good.

I all so checked the final with my transistor tester and it tested good.

Has anyone seen this before.

I have a extra cb on bench and no antenna on it I can here my self on the bench cb when I key up but no watts on radios meter or watt meter .

Thanks in advance for any help troubleshooting this problem.

How much (Peak to peak) does the scope show on the finals?

Is this into a dummy load or antenna??

When connected to an antenna, can other people hear and how far away??
