Hi all,
I finished the second stage of assembling the K2, (RF part 1) and
started the allign and test procedures.
I saw the S-meter stuck at the last led (nr 10) during receive and no
audio on the headphones and with the RF-Gain full CW.
(It actually doesn't make any difference if the RF-Gain is full CW or
CCW in my particular case).. I ignored this and started the alignement.
All went fine but ending up at the 40 mtr RX test, no wonder, nothing to
hear!.
The strange effect I noticed is when entering for instance the CAL mode
XFIL the audio noise comes on and the S-meter goes down.
But when leaving the calibration mode, the S meter goes high and audio
fades away, just like the RF gain is turned back on (which corresponds
with each other). I tried to calibrate the AGC Threshold and S-meter
again but as I expected, this is not a solution. It looks like an RF
-gain problem, which I didn't have when I had my first alignment.
I checked the boards for short circuits and cold solder joints but
didn't see anything (I might oversee something). Unfortunately I have no
signal generator available at the moment.
Who has got an idea ?????????
