I'm also using N4PY with my Flex 5K and my Orion 2, coming off the 2nd
receiver RX input to the RX-In port on the Flex 5K. Works like a champ!
One can certainly get addicted to point and click tuning, especially on CW.

I'm using the Flex-1500 in the receive loop of a OMNI-VII and using DXLab's
Commander to control both radios in "Lead, Follow, Lead and Follow" so that
the OMNI-VII controls the Flex, the Flex controls the Omni, or Commander
controls both. In split the Flex always follows the on the Omni-VII transmit
frequency. Since the Flex-1500 is in the RX loop, it is protected when the
OMNI-VII is in transmit (I have optioned the FLEX-1500 as receive only to
protect the OMNI's RX from damage by the FLEX PA). And the 10 meter RX is
great.... I had lots of fun using both receivers during the ARRL 10M SSB
contest.
At $650, the FLEX-1500 is about the cheapest panadapter one can buy. The mod
to the OMNI-VI (N4PY Sub-RX mod) takes less than 10 minutes, NO Solder, and
costs less than $5!

Haven't tried the Flex-1500, but have used an SDR-IQ that way with my
Yaesu FT-1000MP Mark V. Fed the SDR-IQ the same signal that went to the
Mk V receive antenna input using a hybrid splitter. The same approach
could be used with any transceiver with a receive antenna loop (output
and input). I ran into two problems: The SDR-IQ was relatively deaf on
12 and 10 meters and weak signals that could be heard on the Mk V
couldn't be seen on the SDR-IQ. And - it was obviously necessary to
mute the SDR-IQ during transmit and there was apparently no way to
accomplish that (grounding antenna input wasn't adequate).
What would be nice is a TenTec external spectrum scope similar to the
P3, that would sit on the PC to Orion serial port interface (as the P3
does with the K3) so the scope unit could send frequency setting
commands to the Orion. And, wouldn't it be nice if the very same scope
could be connected to the Eagle in the same fashion. A nice scope is
really a good addition to a 6M rig.
