This is a follow up to the thread "[K3] Subreceiver IF output". I use two LP-Pan with my K3; one on the main-Rx IF and one on the sub-Rx IF. I added the 10-dB preamp from TelePost, Inc. to provide additional 35 dB isolation similar to the Cliffton Labs amplifier. This also lowers the noise floor by 8 dB which helps with weak-signal detection. http://www.telepostinc.com/Preamp.html
The two LP-Pan run on one LO so they are locked for diversity reception using the K3 (see the same web reference I gave in the earlier reply). I have a SDR-IQ (SN-002) which I use for mainly 600m reception but can also be used in place of the LP-Pan. The LP-Pan has more choice in SDR sw that will run with it. I did download SDRConsole but not played with it very much. PowerSDR (from Flex) and NaP3 are popular. I plan to get NaP3 to tryout with the eme0202 soundcard running 192-KHz span on HF. On eme I only need about 60-KHz span but can run up to 90-KHz if desired (limitation of the Delta44 soundcard). WSJT9, WSPR, and MAP65 are the sw run for with it. The signal capture/decode feature of MAP65 is similar to CW skimmer in capturing all stations within the span...a great asset in eme contests (which I intend to test in the upcoming ARRL EME Contest - Nov/Dec). Since I am running my 2m-eme station with adaptive dual-pol diversity Rx there is never any loss due to cross-pol which effectively give up to 3-dB more performance over my previous Horz/Vert switched polarity system. refer to my website for full info on my eme/vhf-uhf/mw projects: http://www.kl7uw.com 73, Ed - KL7UW ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
