Additional Info on Problem

SABorns
On double checking the BFO Test (pg 62 of manual) the BFO Low Freq. is too  
high. The manual says it should be less than 4912.7 mine is 4912.86. How can I  
lower it?

RE: Additional Info on Problem

This was covered in a post on the reflector a couple days ago - a small
padder capacitor from the junction of X3, X4 and C174 to ground may solve
your BFO low frequency problem.  Use 1 or 2 pf and recheck both ends of the
BFO range after adding it.

Normally 4912.86 can be low enough except in extreme cases - note that the
LSB BFO is set at 4913.7 which is well within your currently available BFO
range.
