Going full duplex with amateur satellites, part 5 : first test of the amplifier with RTL-SDR / 2017-04-14

2017-04-14 Going full duplex with amateur satellites, part 5 : first test of the amplifier with RTL-SDR5 months ago
For a first test I looked for the first reasonable pass of an amateur satellite and tried to recieve the morse beacon of HO-68. I have received signals from HO-68 before, but this pass I heard nothing.

I tried a stable regular local source on the 70cm band : the PI2NOS repeater and noticed after a while the frequency display in Gqrx was showing 430.100 MHz where the (GPS stablized) frequency is 430.125 MHz, so the RTL-SDR I use is somewhat off frequency. Maybe in a next test things work better.
