I'm surprised the Flex-5000 is so deaf. My 1500 receives perfectly well down to about 480 something kilohertz, then the bandpass filter clicks out and all heck breaks loose. Lots of room to hear most of the 600m band. I guess there's something different in the hardware...well, there's a ton different in the hardware!
I built a simple lowpass filter that opens the longwave band up right down to 100 kHz. It probably works down further but there's not much down that far that can be decoded with one's own ears. "Don't sell longwave short." I see a new bumper sticker in there somewhere! :-) 73, Ken VE3HLS ________________________________ From: Jeff Singer <jsin...@i1.net> To: flexradio@flex-radio.biz Sent: Sunday, February 19, 2012 10:02:51 AM Subject: [Flexradio] The new 472-479 kHz band - REAL DX My Flex-5000 is utterly deaf below the U.S. AM broadcast band. Can't even pick up local airport Non-Directional Beacons. But I do some longwave listening with my old Kenwood TS-850/HF vertical and often hear European AM broadcast stations in the 150-200 kHz range even from my QTH in Missouri. Radio France Inter can often be heard from local sunset until sunrise in Europe on 162 kKHz. The BBC station on 198 kHz is almost as loud. It's easy to assume that these signals are spurs from local AM stations but they make the very long trip using immense power, often above a megawatt. Even very low power 600-meter ham beacons around 500 kHz can be heard over most of the U.S. Don't sell longwave short.
