I imagine you examined several panadapters before opting for the fairly
expensive Perseus. What were the persuading features that drew you to your
choice?

Subject: [Elecraft] K3 and Perseus SDR panadapter/receiver
This week I bought a Perseus receiver and have it hooked up to my K3 via
"com0com" and Ham Radio Deluxe to act as a panoramic display for the K3.
I am not using the insensitive IF out of the K3, instead I am using a home
made ferrite hybrid splitter on the KXV3 RX RF out/in of the K3, one port
goes to the Perseus, the other to the KXV3 RF input (not the main antenna
socket). The loss through the splitter is 3 dB.
In order to run the above combination, the freeware program com0com
(http://com0com.sourceforge.net/) is run to create virtual com ports 10
and 11 -instructions for doing this at the Sourceforge web site. Power up
the K3 and the Perseus (including it's perseus.exe software). The the
latest version of HRD should be run twice, one application controlling the
K3, the other the Perseus. In HRD click the "Synch" button and link the
two radios together. I use the Perseus as "Master" (sorry politically
correct people, but that's what it's called). It works great with full
dual receive and "click and go", the K3 tunes within a hairs breadth of
the Perseus which has the benefit of a 1ppm TCXO too. You can set the K3
as master and have the Perseus follow, but I mostly use the "click and go"
where the Perseus drives the K3.
The noise reduction of the Perseus is currently better, in my opinion,
than that in the K3 when dealing with wide band white "frying" noise and
the Perseus has synchronous AM - needless to say it works very well on
those 80m AM stations and of course broadcast stations.
The Perseus is more expensive by a long way than the simple Softrock
receivers and LP-PAN, but it is darn good.
