P3 Beta 0050 - Transverter issue

I have downloaded the new Beta for the K3 and P3, all seems to be working OK
on the HF bands, but I seem to have a problem with the P3 when using my 23cm
transverter on Xvtr Band 4 (converting to 28MHz). On all the other bands I
can get the usual panadaptor and waterfall displays, but on 23cm there is no
spectrum display on the panadapter (for any signal level or ref level) but
the waterfall turns bright red across the screen. When first powered on I
can see what looks like a correct display for a second or two, then it
disappears. The P3 transverter gain calibration setting does not appear to
do anything, having selected band 4, pressing the knob again gives an
onscreen display of "nan" and turning/pressing the select knob has no
effect. Anyone seen similar symptoms?

John,

That's a strange one. The transverter gain is supposed to default to 25
dB. If you can't adjust it with MENU:XV Gain, then you might try the
"Parameter Initialization" procedure on page 24 of the manual.

Thanks Alan, a Parameter Initialization seems to have sorted it out OK. By
the way its on P26 of the current manual on the website. The new fixed tune
mode is exactly what I was waiting for, thanks to all at Elecraft for the
continuing evolution.

John

mine does exactly the same when setup as you did. I went back to the
previous revision

It also did the same when converting 902MHz to 28MHz on xverter band 3
