Hi All, I'm still trying to troubleshoot my high currant drain on RX (0.5A), as well as
my 8VR line remaining at 0.6V during TX ..
Going through the troubleshooting I see that a problem in the AF section could
lead to low audio outpuit and high currant drain..
My question is, what sort of audio output should I expect from headphone socket
and speaker. I need to have the volume control at about 3 O'clock comfortable
listening on the speaker, and at about 1-2 O'clock for mt headphones (Sony
Walkman Type). Is this normal or should I expect more output volume.
I also notice that one of the trouble shooting steps for the AGC is to listen to
second harmonic from X-tal X1 (Control Board) on 10.136Mhz. Whilst mt S-meter
seems to be working I can't hear this harmonic.. Is it worth me putting the 22K
resistor on U1 as suggested.
I was able to try the K2 in the contest at weekend and whilst the TX side seems
fine, I still suspect that the RX is a little deaf.
Regards
David, VK2NU
