Antenna Question
by Brad Smith 26 Jul '19

26 Jul '19

I have two Arrow 2 antennas and have been using them since 2013 on FM satellites. I use a Kenwood TH-D72 radio which is full duplex, so I can hear myself very well when I get into the bird. I am wondering about a phenomenon that I experience and why it happens. It is much easier for me to hit the bird (and I have a much louder signal) when the bird is just about on the horizon than when it is directly overhead, or at a very high altitude. This should not be the case, as overhead it is only 400 miles away, but on the horizon, it is 2,000 miles away. But I am so much louder at the horizon. I "boom" into the bird. Does anyone have any answer to why this is? Brad KC9UQR

SatPC32 Not responding with 9700
by Richard Lawn 26 Jul '19

26 Jul '19

All was well until suddenly SatPC32 started to not respond and lock up. I'm using Win 10 with the most current version of SatPC32 and the Icom 9700. I left the station for about a week but have made no changes since all last worked. Any suggestions? Uninstall SatPC32 and reinstall it? Rick, W2JAZ

Fwd: USNAP1 lives! - capture UHF data pse
by Robert Bruninga 26 Jul '19

26 Jul '19

It looks liike PSAT2's sister cubesat finally woke up today (a month after launch) at 0614z on 25 July: http://www.findu.com/cgi-bin/raw.cgi?call=usnap1-1&time=1 The VHF telemetry shown here has only bus voltage. The digipeater is OFF and will remain off until we find out what happened. In the mean time, we need all the capture we can get of the 9600 baud downlink on 437.605 MHz +/- Doppler. There is a beacon every 30 seconds. Bob, WB4APR

WD9EWK @ DM54/DM55 on Saturday (27 July 2019)
by Patrick STODDARD (WD9EWK/VA7EWK) 25 Jul '19

25 Jul '19

Hi! I am planning a day-trip to the DM54/DM55 grid boundary on Saturday, 27 July 2019. The spot I will use is one I have visited a few times in the past, along old US-66 and next to the I-40 freeway in Navajo County, Arizona - between Holbrook and Petrified Forest National Park. I hope to be out there between 1600 and 1630 UTC, and plan to operate until sunset (weather permitting). I will work FM, SSB, and - if available - packet from there. QSOs will be uploaded to Logbook of the World after I return home, and QSL cards are available on request. My travel to and from the DM54/DM55 grid boundary should be visible on APRS as WD9EWK-9, and can be seen at (among other places): http://aprs.fi/WD9EWK-9 I will use my @WD9EWK Twitter account to post updates during the day. If you do not use Twitter, you can still see these updates in a web browser at: http://twitter.com/WD9EWK 73!
