RaDAR – AO-91 ideal for RaDAR Ops

I’d heard that a simple dual band handheld could be used to work this newly launched cubesat so I decided to give it a go with the absolute minimum. At 12:43 local time I called from the roof of my saltmine here in Lichtenburg, Northwest province, South Africa using my TH-D7A and a slighly larger dual band whip I’d bought for it many, many years ago.

I heard NOTHING!!!

I called on the uplink 435.250 MHz FM sometimes adjusting 5 kHz down then up initially to account for 70cm doppler but still heard nothing on the downlink.

The down link is supposed to be 145.960 MHz FM and there should be no need there to adjust for doppler.

BUT, when I got back to the Office a recording was posted on our WhatsApp HamSat group ….. the guys heard ME!!!

Half way there ๐Ÿ™‚

Had two QSO’s at lunch time, one with ZS2BK and the other with ZS40VDK, special event station ๐Ÿ™‚

I used the TH-D7A on full duplex and Arrow yagi. Downlink was 59+++++
