I have a K3 that has the higher gain IF output (#3460). I follow the IF
output with the Cliffton Labs buffer and then a SoftRock SDR for a panadaptor.
I use Rocky SDR software by VE3NEA for my weak signal panadapter. Power SDR for
non weak sig conditions. (mostly HF)
Since my interest is VHF-Microwave, the K3 is preceded by transverters for
all bands 6meters and above. I DO NOT have QRM issues at these frequencies
(except perhaps 6m during Es season) and as a result I run my noise floor at
28Mhz on the K3 at about S2 for all the transverters. I feel that a little bit
of IF gain helps with detecting weak siganls on the panadapter.
I can see signals on Rocky (CW sigs are easier) that I can not copy. It is
this weak signal spotting that is why I want the panadapter. When I compare
this panadaptor to a very optimized SoftRock 28Mhz IF paanadapter system, I am
giving up at worst a couple db.
I CONTINUE to be very happy with this combo. VERY weak SSB signals are hard
to see in the noise HF or VHF.
