Hi Alan,

Thank you for your help. Following your suggestions, here’s what I found;

1. I checked the continuity of all the windings on T1, as well as L1, L2, L3 and L4. All were good.
   
   

2. I checked the Peak BPF and while adjusting it noted that with C1 fully meshed, the maximum amplitude was 4, with 6 large segment bars on the scale. As I rotated C1 to fully open, the number of bars increased from 6 to 13. It didn’t look like a sudden jump.
   
   

3. I then checked the phase adjustments with the volume set at about 50%.

I-Q Balance was an amplitude of 6 with 50% of the bars

Phase Lo was 5 with 50% of the bars.

Phase Hi was 6 with 50% of the bars.

I checked the transmit power with a meter into the dummy load and it was exactly 4w.

You also mentioned doing voltage checks. Are there any instructions somewhere on the procedure for that?

Thanks again.

John
