[Elecraft] P3 SPAN Instability

[Gary J Ferdinand]

Various searches dredged up nothing helpful.  I recently developed a P3 problem.  The SPAN does not get saved.  Whenever I change bands to a band I had set it, say, to 50 kHz, the SPAN resets itself to 5 kHz.  Sometimes I can even watch the display as it cranks down the bandwidth.

This is a P3 *without* SVGA, but *with* TXMon.  It has 1.60 firmware installed and reloaded without effect.  It is not directly connected to a PC. The transceiver to which it is connected is a K3S.

P3 SPAN settings:  SpanScale: REF LEVEL ONLY, SteppedSpan:  OFF

I appreciate any pointers to where I should look.  Thanks.
