around with a USB SDR fed from the IF of my K3 for a couple
of years. It was OK but fiddly to set up.
bought a 2nd K3 with a “free” P3 thrown in. I
was very dubious about its little screen … until I started
using it. Now I really miss it operating a plain K3 at the
LCD display is bright and clear. I have tried the VGA
output on a large screen but it’s no better for me and just
wastes desk space.
lots of useful things:
- My noise floor on different bands
and antennas, and hour-by-hour variations
- Where the signals are when I’m
tuning across a quiet band hunting for signs of life
- How much activity is there on
FT8, FT4, RTTY or other digimode segments
- Where DX stations are
transmitting, and where they are working split, tuning
through or jumping around in their pileups
- Gaps in a busy band where I might
CQ, or gaps in a DX pileup where I might call the DX.
- QRN bursts – are they
strong/frequent enough to make the band unusable, or only
light & occasional?
- QRM from radar, intruders,
pirates, data crud from my station etc. – would it help to
shift HF or LF to avoid them?
- ‘Sweepers’ from the sun on an
active high band, plus human tuners
thing I really miss from my SDR setup is the ability to
overlay callsigns from cluster spots or Skimmer or (I guess)
data decoders, on the waterfall. It would be too much for
the little P3 LCD but would be handy on a desktop screen.
[I used a Flex radio in CQ WW CW with a front-panel
panadaptor display that could show callsigns: it was too
crowded & busy for my liking, but then I only had a few
hours in the dead of night during the contest to learn how
to use the radio!]
So, all in
all, I’m a convert. The P3 has turned out to be a
worthwhile addition to my station, more use than the 2nd
K3 in fact!
The P3 box
is mostly empty. I’m tempted to separate out the LCD to
fill a more convenient gap right in my eye-line rather than
off to one side. Maybe I’ll try adding a little external
tried the RSP1,1a and the 2 . Didnt really excite me. I
also fed the 9mhz out to the input of my 7300 ! . It
havent figured out why I need some fancy colored screen to
show me who is on the band. I dont use the scope on the
7300 either. To each their own but it seems like just eye
candy to sell radios. Being pretty much a dxer I just
watch the spots .
are options though.

I have an FTDX5000, LP-Pan 2 +
Soundcard + NaP3/CW Skimmer. The CAT from the rig is shared
(including to/from Logger32) via LPBridge.
If you just want to try a
panadapter get one of those cheap SDRs you find on
eBay/Amazon and feed it from the IF out on the back of the
FTDX5000. You tune the SDR to 9MHz and you get a 'reversed
display' ie if you are Rxing to USByou need to tune the SDR
to LSB, well thats what I found.
SDR# (SDR Sharp) supports the
cheap RTL-SDR USB devices and you can buy these with an HF
down-converter. They're not very sensitive but they give you
an idea of what you can see. Just don't buy an VHF only
I hardly use the NaP3 visual
display expect during an SSB contest or looking at
interference, but I use CW Skimmer all the time..
