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.
