Yes a click is a better description. It is very consistent. The 
soldering is excellent on this radio. Flowed through both sides on 
everything. I used good equipment and a grounded blue mat bench top. No 
static issues. I will do that CAL PLL again. The VFO cal is real close 
to WWV on 10mc and also matches my 3mc oven oscillator and DDS VFO also.

I'll do that & report back...hi hi...

Thanks much,
Mike
