The July 18-25 Lesotho 7P8 DXpedition sponsor by the Lone Star DX Association and the Texas DX Society has added amateur satellite mode to its planned operations,DXpeditoin Leader Charles Frost, K5LBU/7P8TA has announced.
The operation will be on the AO-40 satellite. The uplink will be U–band (70cm) uplink on U-band 435.550 to 435.800 MHz CW/LSB and S2 (2.4GHz) downlink 2401.225 – 2401.475 MHz CW/USB, Frost said. The AO-40 satellite was launched Nov, 16, 2000 aboard an Ariane 5 rocket from Kourou, French Guiana.
Equipment including antennas and a down converter were donated by Wayne Estes W9AE and a spare down converter donated by Bruce Paige, KK5DO.
Paige, qsl manager for the recent P5/4L4FN operation from North Korea is also providing pre-Dxpedition satellite training in Houston.
Paige is AMSAT VP of User Services & ARRL Awards Manager (WAS, 5BWAS,VUCC).

We re glad to offer such a needed mode from Lesotho, Frost said,adding that those wanting to make a contact with the DXpedition take it easy on us because none of us are satellite operators, but we are willing to try our best at giving everyone who wants one a 7P8 QSO.

P PcSats hemsida finns det att lsa fljande:
END OF MISSION: PCsat was in full sun 10-20 April 2003 and continued to be power positive until 26 April. At that point it was back into heavy eclipses and the batteries are so weak that even in the sun, they can barely support a single packet. I m declaring PCsat mission as complete. It operated reliably for 19 months and supported over 2000 users worldwide. We were seeing typically 50 users in each 8 hour period on pcsat.aprs.org. So she was well used up until the end. We will leave her ON for continued experimentation, but the only packets you can get through PCsat now are very short ones.
Och Bob tipsar om hur man skapar sm paket att testa med:
– Mic-E formatted Packets (position, Course, SPeed and ICON)(only 9 bytes in the payload)
– Kenwood D7 and D700 s use the Mic-E format (Turn off any status text)
– Transmit VIA XBAUD and your 1 second 1200 baud packet will be digipeated back down at 9600 baud
– Set your radio to crossband and TX at 9600 baud on the UHF input.
