CubeSats launch successfully!
Four CubeSats containing payloads operating on Amateur Radio
frequencies were among several spacecraft launched successfully April
17 at 0645 UTC from Baikonur Cosmodrome, Kazakhstan. A Dnepr rocket
deployed seven CubeSats plus seven other satellites from Egypt, Saudi
Arabia and Ukraine into Earth orbit, and signals from the four CubeSats
have been copied on Earth. Among the spacecraft was Colombia’s first
satellite. The CubeSats are: CalPoly’s
PolySats CP3 and CP4 (similar to photo), 436.845 MHz and 437.325 MHz
respectively, 1200 bps FM AFSK, AX.25, 1 W, operating under an FCC
Part-5 Experimental license; University of Louisiana
CAPE-1
435.245 MHz, 9600 bps FM FSK AX.25 and CW telemetry during opposing 30-second intervals, 1 W,
call sign K5USL (e-mail telemetry reports);
Universidad Sergio Arboleda, Colombia,
Libertad-1,
437.405 MHz, 1200 bps FM AFSK AX.25, 400 mW, call sign 5K3L. CP4 will
transmit a “sensor snapshot” every 2 minutes on 437.325 MHz at 1200bps
FSK, AX.25. FSK will require using SSB mode for reception. A 6-second
CW preamble precedes this transmission. Keplerian elements for the new
ham radio birds and additional information will be posted on Cal Poly’s
CubeSat Web page. CalPoly offers a CubeSat
“Satellite
Contact Form” to report telemetry data received from any satellite.
A discussion board also is available for satellite trackers.

We are shipping out the last TC70-20Sa ATV Transceivers today. We cant
make another production run because the 20W power module is no longer
manufactured. We have a few modules left for repairs and PA5’s, but not
enough to justify the cost of a small production quantity. Meanwhile,
we are working with Videolynx to come out with a 5-10 Watt 70cm
Transmitter. Watch our New for 2007 web page for the announcement on
availability and price, but we expect it to be ready this summer. It
will work with the Mirage D1010N-ATV or DEMI 70225PA linear amps for
higher power and with our TVC-4G downconverter to receive. For those
that cant wait to get on, you can package your own system using our
board modules or use the RTX70-1 1 Watt transmitter driving a Mirage
D26N 50 Watt pep amp - check out our web site.

President Recognizes California Radio Amateur's Dedication to Volunteer Service
President George W. Bush has
honored ARRL member Randy Hatfield, AG6RH, of Victorville, California,
with the President's Volunteer Service Award.
A volunteer with the City of Victorville Community Emergency Response
Team (CERT) and Emergency Communication Service, Hatfield met briefly
with the president April 4 to receive the award. President Bush honors
local volunteers as he travels throughout the United States. When a
call came from the White House, Hatfield at first thought he was the
victim of an April Fool's Day prank by ECS Coordinator Robert Barton,
W7OES, who nominated Hatfield for the award a few days earlier.
The Daily DX debuts back issues search engine
The Daily DX editor Bernie McClenny, W3UR, says his paid subscription DX newsletter’s Web site now offers a Google-powered search engine. Open to all, the search engine scours back issues of The Daily DX.
“I am still in the process of uploading issues and hope to have this
completed by the end of April,” McClenny says. “When completed it will
have up until the last 6 to 8 weeks.” So far, McClenny says, he’s
uploaded back issues from March 17, 1997, through May 2006. Issues of The Weekly DX are not included. The “Google Custom Search” box is in the middle of The Daily DX
home page. McClenny advises users to include as many key words as they
can when initiating a search. He also suggests starting with one search
word then adding more words to narrow down the subject.
