I have two observations:
The first - the team control of the AO-51 correctly employed the use of PL tone to activate the bird. Here in South America constantly listen to interference from phones and others strangers broadcasts through its downlink. I hope the use of PL tone is adopted and so permanent.
The second observation is related to EME - our friend Roland, PY4ZBZ managed to received the signals from the Arecibo Radio Observatory on 22/03/2010 at 21:30 UTC in 432.045 MHz with only a small UHF antenna for 6 elements and a simple FT1000d transceiver. Roland with his equipment received signals in CW and SSB. Congratulations to our dear friend Roland, who with his feat, he broke the paradigm that is not possible with a simple antenna on hand to listen to a broadcast EME. Taking into consideration the power and the antenna used by KP4AO.
