Many are using the SoftRock II Specials that Tony sold for IF Panadapter use. They ARE STILL AVAILABLE but are now sold by a different person with Tony's blessings ....
http://www.w6dvc.com/ I have used a Softrock and a Clifton Labs Z100000 buffer from the very beginning and am very happy with the results. I use PowerSDR IF v1.19.3.5 for point and click operation and am happy with the results for the most part. Rocky software is much better than PSDR for weak sig detection, but you loose the Point and Click control of the K3. So for the stuff below the noise I stop PSDR and activate Rocky. Since most of my opeartions are weak signal I run Rocky and operate the K3 in a normal manner. For CW Rocky is fantastic. With 96Khz soundcard setup max resolution is about 15Khz for full width on my monitor. If I want FULL SDR operation, I turn on the SDR1000. It doesn't get turned on that much. (Anyone want to buy a 100w/ATU Flex 1000? ) The K3 is what is running here full time. I am curious about the P3, but I can't yet justify the expenditure given the performance of my SoftRock/ Clifton labs/ homemade PC Box panadapter. The SR and buffer are hidden from view behind the K3 and are in operation all the time I have the K3 on. (Usually 14-16hrs a day). I operate VHF/UHF/Microwave weak signal and a some of HF. My panadapter allows me to look at a 96Khz "window" regardless of the band of operation which I can live with very easily. If I want greater resolution I can change that window with both software packages. For receive only operation with the SDR, the software setup is NOT that big of a deal. The SoftRock gang on the Yahoo group are as helpful as any you will ever meet and will get you going. For about $50 you are set. Don't like it? You can sell the "combo" in a heartbeat on the Yahoo group. http://groups.yahoo.com/group/softrock40/ I can use PowerSDR to provide monitoring of two additional frequencies of the band I am operating as long as I'm not changing frequencies as I monitor. With Rocky one additional freq. During VHF contesting I often operate on one freq while monitoring a rover freq with the panadapter "receiver" to keep track of his availability. Be aware ... if I change freq on the K3 I have to reset SDR "receiver" freq. But I have a second freq option. http://www.qth.net/k0awu/K3System.html Its all a matter of what you want. I have a PC running all the time and a PC based panadapter is no big deal. The K3 never leaves the radio bench and I like the large panadapter at the logging computer. If you JUST want to "see the activity", I see no problem. If you want a single source integrated hardware/software companion to your K3, the P3 is of course the only option. So ... that's my "take". 73 and good DX Bill K0AWU EN37ed -------------------- > Date: Mon, 16 Aug 2010 00:24:50 -0400 > From: w3...@embarqmail.com > To: lesch...@gmail.com > CC: elecraft@mailman.qth.net > Subject: Re: [Elecraft] P3 or KRX3 > > Bob, > > You are partially correct.
