Congrats AMRAD and G0MRF

For your info, I refer to the below item taken from the ARRL Newletter,
Vol19. No.35. David Bowman, G0MRF has been a contributor to The AMSAT
Journal on S-Band to 70cm convertors.  Congrats David and AMRAD!



In the spirit of the early transatlantic tests, a crossband LF-HF contact
between the United Kingdom and Canada was completed September 10. The
contact involved well-known LFer Dave Bowman, G0MRF, operating on 135.711
kHz and John Currie, VE1ZJ, on Cape Breton Island, Nova Scotia, Canada,
operating on 20 meters.

"Dave had a surprisingly strong signal into FN95, Cape Breton Island,"
Currie said in an e-mail message to Andr' Kesteloot, N4ICK, who's involved
with the AMRAD LF experiment in the US.

Using spectral software, Currie reports that he observed "weak dashes" from
G0MRF just after 2205 UTC on September 9. He says noise was extremely low.
Shortly after sunset on Cape Breton Island he observed a lot of dashes. "It
looked like G0MRF was coming across the pond," he said. Bowman's signal was
never audible in Canada.

Currie said he had "solid copy on G0MRF" by 2245 UTC, and the crossband QSO
was completed on September 10 at 0008 UTC. "I could see every dot and dash,"
he reported. By 0100 he could no longer copy the signal, and by 0250 UTC
they were fading. "I did not see them on the spectrogram again," he

Bowman says he was operating from a 15th floor West London apartment, the
home of Sean Griffin, 2E1AXK. The antenna was two sloping 250-foot long
wires about 80 degrees apart. Grounding was via the building's plumbing.
Loading involved fixed and variable inductors. Bowman estimated maximum
power into the antenna at 700 W, but at one point, he dropped his power to
about 320 W and VE1ZJ was still copying. "Even allowing for the large
antenna, I believe this shows that many UK/EU stations will be able to make
the transatlantic path this winter," Bowman said.

Canada has not yet authorized Amateur Radio operation at 136 kHz, but some
stations have been given permission to experiment there. Larry Kayser,
VA3LK, and Mitch Powell, VE3OT, completed the first two-way LF contact in
Canada on July 22 on 136 kHz, using very slow-speed CW (dubbed "QRSS").
Kayser is testing equipment and processes in preparation for the
TransAtlantic II attempt on LF set to occur November 10-27 from
Newfoundland. TransAtlantic II will attempt to span the Atlantic in both
directions on LF. Details on the project are available at

The Amateur Radio Research and Development Corporation--AMRAD--has been
involved in a low-frequency experimental beacon project in the Northern
Virginia-Washington, DC vicinity. AMRAD has been conducting tests on 136.75
kHz from 12 Northern Virginia sites using the experimental call sign WA2XTF.

The ARRL has petitioned the FCC for two low-frequency amateur allocations.
