500-kHz DISTANCE RECORD !

On Jan. 17, experimental station WD2XSH/20 was received on Roi-Namur in the Marshall Islands (4737 mi) by Neil Schwanitz, V73NS/WB8CRT. WD2XSH/20 is located in Cottage Grove, OR and operated by Rudy Severns N6LF. The transmission in CW at about 13 wpm was copyable by ear and appears in the Spectran capture as well. "SL" in the capture is an NDB on 505 kHz located in Khomotovo, Russia.

SSB operation on 600 Meters? You bet!!

Here's a recording made by Dick, WA3USG on January 27, 2008.
Dick reports: "Here's a snipet of the SSB activity on 510 KHz Sunday evening. I copied WE2XGR/1, /2, and /3. This is using my SDR/IQ and my AMRAD E-Field probe. Boy, down here the audio almost sounds like good A.M. modulation!"

Rik Strobbe ON7YD is now on the air from Belgium. Here's his report:

" I want to inform you that since 29 January I am QRV on 600 meter. Temporarily only on 503.1 kHz with about 0.5 Watt ERP but in the near future I intend to increase my ERP to about 3 Watt and will be able to transmit the in entire 501-504 kHz range. The call used is OR7T.

" According to the recent decision of BIPT (Belgian FCC) any holder of a full licence can operate 501-504 kHz with maximum 5 Watt ERP on a secundary (non interference) base. Mode is limited to CW (including QRSS). In the past days I have been able to work about a dozen UK stations (G, GW, GI, GM), best DX is GM4SLV at about 1100km. In the same period I received reports from PA, F, DL, G, SP, OK, SM and OH (best DX 1680 km). "

UK Hams on 500 KHz are now allowed 1 Watt ERP.

RECEPTION REPORTS

You do not have to be a member of this group to send us a reception report.

Reception reports are welcome for ANY 600-meter station - not just WD2XSH stations. Multiple reports on the same station on different dates and times are encouraged as they allow us to see that communication is repeatable

The entire Amateur Radio community stands to benefit from your assistance!
