I have both with my K3. If I could have only one, it would definitely be the P3. The sub RX is great for diversity receive which helps a lot in CW contesting. But the P3, as other have pointed out, lets you quickly find where to place your signal when trying to find a good run frequency. For DXing, I think it is pretty much a tossup.
But one aspect of the P3 that no one has recently mentioned is that it makes a SUPERB piece of test equipment when used with the K3. I don't have a dedicated spectrum analyzer but found that the P3 meets many of these needs. I use it when designing and characterizing filters. The ability to easily download and print out plots in full high resolution color is amazing. I often use it with the Elecraft noise source as an input signal. Of course I have the general coverage bandpass filters K3 option, which I highly recommend. And the K3's functionality as a calibrated tunable RF voltmeter is awesome as well. The P3 is also invaluable as a tool for tracking down EMI. You can see the type of signal and how it is moving in frequency vs. time. I use it for this both with the K3 and also as a portable battery powered standalone EMI receiver by setting the programmable IF frequency to the range of interest and using a small hand-held loop antenna. For anyone with an interest in home brewing and circuit design, I can't recommend the K3/P3 combo highly enough. 73 Craig AC0DS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
