Subject: [Drakelist] My New 4 - Line....Issues but I'm
loving it
Ok, connected up the AC-4, fired up the transmitter
(sorry, poor choice of
words) and tried to tune it up on 40 after adjusting AC-4
bias. It seems my
peak when adjusting RF-Tune was down in the 80M
range...I'm not sure if
that is normal. Anyway, I need to clean the switches
before I proceed on
the transmitter.
On the R-4B, I received the 6CA5 to replace the tube that
was broken when I
received the equipment. The receiver seems to work like a
charm on all
bands but 15, absolutely nothing on 15. Without an antenna
I can adjust the
pre-selector for a noise rush on all bands but 15. Where
do I begin?
The audio sure sounds sweet from the MS-4 on the other
bands, great audio!
Tnx,
Rick - WA4RG
Test equipment on-hand for troubleshooting: DMM & 100Mhz
Scope
Could be a bad crystal for that band or a dirty switch
or crystal socket/pins. I suggest cleaning the pins and
socket and the band switch. The crystal may even just be
loose in the socket. If the crystal is bad new ones can be
had from International Crystal or Bry Carling.
