[TenTec] Anyone using LP-PAN with Orion/RX366?

Floyd -

I have the Orion connected to LP-Pan via the 9MHz IF in the main 
receiver.  It works acceptably but has odd dips in the display around 
the selected frequency.  They vary depending on the roofing filter 
selected.  Most folks aren't bothered by this and the dips are 
eliminated if you have the hardware noise blanker on.  But, I wanted 
better, like I have with my K3 and LP-Pan.

I bought the RX-366 and used it with my LP-Pan with these results:
- no dips, but a hump in the display near the selected frequency.
- a significant spike on the display about 11 kHz below the selected 
frequency.
- the RX frequency is that of the sub receiver so you have to have the 
sub-receiver track the main receiver for point and click QSY. N4PY 
software can handle that for you.

Nothing is perfect.  In the end I could tolerate the shortcomings of the 
9MHz main receiver IF better than the RX-366 issues and returned the RX-366.

You may feel differently.
