Default Re: RA1772 again. Frequency 100kc/s out

Last night I clipped my new logic probe onto the Upper Loop board, moved the wiring about in order to identify the pin numbers and the fault cleared. No obvious bad connections and I can't get the fault to come back for now.
So now the 1772 I bought as spares or repair seems to be better than my original!
I would like to read about the multiloop synthesisers but I see my latest ARRL handbook is 1991. However, I see there is lots of info on the internet and in the manual.
Thanks again for all the interest and advice.
