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

I finally got my LP-PAN hooked up to my RX366 and just wanted to post
an update. I've only been using it for a short period of time. I'm
connecting the RX366 IF output directly to LP-PAN with LP-PAN internal
preamp installed. Viewing it with NaP3, I am not seeing the "birdie"
or "spike" at 11KHz offset. The display looks clean and flat so far.
Signal levels might be a bit low but it's working and I need to play
with it some more.

> 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.

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.

I've been using LP-Pan/NaP3 fed from a tap on the main receiver through the Clifton Labs buffer amp. I set the gain on that buffer to either 3 or 6 dB when I built it and that's proven to be a good level. I have the newer LP-Pan with the preamp, but I run with it off as the additional gain just isn't needed. If I had built the buffer with zero dB gain, the preamp may have been useful.
