First, many thanks to NCCC member Robert for the loan of his callsign. It's a really nice CW callsign to use in a WPX contest. My new Microtelecom "Perseus" Software Defined Radio (SDR) arrived from Italy just a few hours before the start of the contest, but I did NOT have any time to to make it work with CW Skimmer. The Perseus is not yet one of the SDRs that CW Skimmer officially supports. So, though it would have been nice to finally try CW Skimmer in a contest, without having a working SDR, there's really no good way to make use of it. So I used no automated CW decoding or spots of any kind during this contest. However, the new Perseus SDR *did* give me a very nice band scope with a beautiful waterfall display, something I have always wanted to have during a contest. I did not monitor the SDR audio, I just watched the SDR's waterfall display. Details follow. I was configuring cables and switches until just a few minutes before the start. Using the station bandpass filters and the transceiver's "RX IN/OUT" lines, I was able to "share" the main transmit antenna of either radio with the SDR receiver. The Perseus was hooked into the RX ANT line just as you would connect a separate outboard receiver: RX ANT Out ----> Power Splitter or T-connector To one side of the splitter connect the SDR. To the other side connect a cable that you loop back into the transceiver's "RX ANT In" line. Press the "RX ANT" button on the rig to activate the ports, and the two receivers are now sharing the same antenna. I added one more coax switch to select which radio would share the SDR. The T/R relay in the transceiver protects the SDR from the band it is sharing, and the station's bandpass filters protect the SDR from the other transmitter, on a different band. The waterfall display was quite hypnotizing to watch. Even the weakest signals showed up as faint lines in the display. The Perseus SDR is a serious receiver that doesn't seem to have any major overload or sensitivity problems. The included software works remarkably well. It was really fun to watch an entire band at once. The FlexRadio products are the only amateur transceivers I know of that have this type of waterfall display "band scope" built right in, thereby eliminating the need for a separate SDR. As for the contest itself, I mismanaged my off time, finding I just had to go to sleep when I really should have been operating. Maybe it was the hypnotic new display. :-) Congrats to NY6N (N6MJ) for another superior result. Activity levels in the US seemed remarkably good. I do wish conditions to Europe and Japan had been better from the West Coast USA in this one.
