I'd previously not been able to receive anything but a couple of local aero beacons on longwave, nor anything but the Christian megawatt at 3200 on the 90 meter band. I didn't care much about the longwave since the very useful aviation weather Elmira NY on 385 khz was replaced by better service on 162.40 Mhz vhf. Last week, just for fun I made a Hi-Q parallel resonant tank for longwave from a 385 pf variable cap and a 3.850 mh inductor. (82 turns #24 awg wire on a 1.3" audio toroid core) This tunes 520 khz down to 170 khz with a pronounced peak. I coupled it very loosely (2 1/2 turns) to the coax near the RCVR and was astounded at the difference in reception. Around 0500Z I logged 15 different aero beacons at between 260 and 420 khz ! The tuned circuit didn't bring the signal levels up...it took the noise floor DOWN ! Has anyone bookmarked the longwave site whcih gives freq's, calls and locations? Just for curiousity I'd like to find out where some of these beacons are.

The ones you have listed is the Upper Sideband - which is the way to get the beacons. Hope this helps, Dave |
