I got a new DX 959. Not the newer blue version.
I was going through the service manual info on CB tricks.com to align the PLL and TX sections.
I noticed the LSB (L22) and USB (L21) adjustments are located underneath the frequency counter board.
How does one remove the freq counter board to reach the alignment locations?
The AM (L20) can be seen just in front of the freq counter board.
I was able to adjust L20 to proper frequency.
On the TX alignment procedure it says to
USB OSC:
Set radio to CH 20 USB TX mode. Connect frequency counter to TP6.
Adjust L24 for
10.69250 MHz ±20Hz.
LSB OSC:
Set radio to CH 20 LSB TX mode. Connect FC to TP6.
Adjust
L25 for
10.69750 MHz ±20Hz.
When I follow the steps and probe TP6 I get nothing showing on my Heathkit frequency counter?
I notice on my radio TP6 has no lead to clip onto like other Test points in my radio.
There is what I think is a diode just below TP6, when I probe it its showing nowhere near 10.69750 on LSB or 10.69250 on USB.
Is there something Im missing?
My radio badly needs the alignment finished for the SSB portion. As expected it is quite a bit off frequency on both Upper and Lower SSB from the factory.
