[600MRG] K3 Owners

[Eric NO3M]

I am wondering if any of filtering is being bypassed in "transverter 
mode"?  I have been using the K3 as the 10 MHz IF rig for quite a while, 
but with the KXV3 parameter just set to "nor" and rig tuned to 30M.  In 
that mode, the band filtering is bypassed; however, in "transverter 
band" mode, the filtering was NOT bypassed.  I don't know if that ever 
changed, but I first noticed this when playing around with 7 MHz LO/IF a 
while back, and finding a nearly 18-20 dB+ loss between modes.

Waiting to get a copy of the beta-test firmware to see if there is any 
noticeable differences in performance, etc., with how it's been running.

TU Jay, W1VD, for the 160M QSO!  Terrible static on the southeast and 
south beverage arrays tonight that is sporadic.  Back to the contest.....

Our inquiries paid off; I got the firmware update from him earlier today. This afternoon I replaced the LO in my transverter with the 10 MHz reference that I also use into the K3. I have the new transverter setup running on WSPR tonight and presto, no frequency drift. I'll leave it running through the night and decreasing temperatures in the shack to be certain, but it looks like the modification was a complete success!
