Re: RF output when just keying the mike

Is your radio receiving ok and have good sensitivity?
Have you tried it on several frequencies i.e. 3 .5 mhz, 7.10mhz and 14.1 mhz? for both RX and TX?

Subject: [BITX20] RF output when just keying the mike
Hi everyone looks like I have problem.
I have RF output of about 5w when I key the mike with no modulation input. When I do speak into the mike the modulation is very distorted as heard on a local SDR.
CW seems fine with a nice clean signal.
The problem happened suddenly while trying to tune up with a manual antenna tuner.
I replaced the two irf510 fets but no change. Anyone have any ideas where I can start looking?
Thanks for any help
