Carl,
Using the method you propose (parallel receiver), how do you make
the SDR track the received frequency so that it signal heard is
always centered in the panadapter view?

I thought the QST article for panadapters was very poor. It
recommended using the IF to feed the panadapter. This is an
archaic method. Today with the SDR receivers available such as
SDRplay, much better results can be obtained without the need for
an IF tap. These new SDR receivers (such as SDRplay) can receive
over a wide frequency range typically from 50 khz to well over 30 mhz.
Because of this, the most modern hookups now just involve
connecting the SDR receiver to the same antenna as the main radio
and running them in parallel with the main radio. This gives a
much wider and more versatile panadapter than being stuck with the
radios IF.
The only obstacle to this is a good way to share antennas without
transmit power from the main radio destroying the SDR
receiver. Some main radios offer a receive out and receive in
loop so with those radios it is a simple setup.
For radios that don't have a good way to share antennas, several
companies offer solutions. For example, one such solution is the
DXE-RTR-1A from DX Engineering.

After reading the Panadaptor article in the FEB 2017 QST I'd
like to try that with my Delta II
Has anyone done this? Where is the tap for the IF?
Suggestions?
