[Elecraft] K3s/P3 with SDR Play, Win4K3 & Skimmer

[Peter Dougherty]

OK, then this will probably all have to wait. I thought it was the other way
around; that the SDRPlay box fed I/Q data into the PC, which Win4K3
interpreted and displayed.

I own an LP-Pan2 and it's full of birdies and mirror images/etc. Tried four
high-end sound cards and they were all the same, and it was far more of a
problem than it was worth. Maybe my PC is just too noisy, which I guess is
possible. 

If my proposed idea won't fly, then what will (short of buying a Perseus or
$$$omething similar)?

Hi,
Win4K3 does not currently provide an IQ out for use with the SDRPlay.
Therefore CW skimmer will not get an IQ feed. (This will come in a future
update)
An LPPAN and a sound card does. This gives you a maximum bandwidth of 192kHz
in the spectrum scope.  CWSkimmer gives less bandwidth so an SDRPlay does
not give an advantage.
In terms of the quality of the signal, the LPPAN / Sound card is superior.
Of course the built in virtual radios allow you to use any panadapter
software such as HDSDR and SDRUno which have the IQ out that can be used
with CW Skimmer.

Hello all.

 

I would like to know if anybody is successfully running their K3/K3s with
(specifically) an SDRPlay, Win4K3 software, and CW Skimmer, and if so, how
did you hook it all together? 

 

My thought is to start reading up now, and then buy the hardware and
software at Dayton this year and play with it over the summer before contest
season starts.

I'm specifically curious about getting RF into the SDRPlay. Do you use the
IF connection out from the P3, or something else? I have three antennas
coming in to my K3s at the moment: the primary TX/RX feed on ANT-1, a K9AY
receive antenna on RX IN, and an untuned vertical wire connected to the AUX
antenna port, which is used only for diversity reception. The radio is
connected via the USB interface exclusively, with no analog sound
connections at the moment.

I don't plan to use this configuration for normal day-to-day operating. I'm
quite happy using the K3 as a conventional radio and just using the P3 as a
bandscope. This will be exclusively for CW contesting, and CW Dxpedition
pileups.

One final question for those who have accomplished this successfully, which
model SDRplay are you using, and is there a specific reason for recommending
one version over another at this point? Thanks again!
