There are 2 FM birds use them and if you need to buy some used ssb equipment do it dont trash a good SSB bird . The hobby is still going good . Learn how to use SO50 and AO27 and enough with this FM on VO52 BRAVO SERRIA crap. Donate to AMsat sothey can put up a new bird . MAN UP enough crying about AO51 and I cant work the birds WA4HFN

Gentlemen,
These are not normal times, we are seriously short of satellites and without satellites we don't have a hobby anymore. Without new and more satellites users we probably won't have a hobby anymore either.
Time for creative thinking.
FM on VO-52 might just be something we have to do.
Send as much money as you can afford to the Fox project

Hi, WA4HFN
Well sayd.............I agree with you !
CW and SSB is just what we have to do on VO-52
BTW, it's impossible to access VO-52 in FM with a 5 watt HT and arrow antennas because for a decent QSO on CW and SSB we need at least 50 watt and a 13 dBi 70 cm antenna.
We, operators of VO-52 linear transponder on CW and SSB we have a lot of counter measures against any FM intruder into the VO-52 linear passband.

???
I don't have a 70cm antenna with that much gain. I currently use an Elk log periodic, started working SSB via satellite with an Arrow Yagi in 2008, and - once - I even used a telescoping whip! My transmit radio for the SSB birds is only at 5W (FT-817ND), and I have worked VO-52 many times and have had many decent QSOs. You do *NOT* need 50W into an antenna with that much gain as a minimum for working VO-52, unless your feedline to the high- gain antenna is very long and/or of very poor quality.
When VO-52 is very high in the sky, I can reduce my transmit power from 5W to 500mW and keep a QSO going. I don't normally cut my power back on AO-7 mode B or - when available - FO-29, since those satellites' receivers do not appear to be as sensitive as the receiver on VO-52.
Five watts (or less) with a directional antenna on all three of these satellites in SSB has added almost 1100 QSOs to my satellite log, about 10% of my almost 11000 satellite QSOs. And all of those almost 1100 QSOs were made from portable stations working from many different locations across the continental USA and three other countries. This may not be a large percentage of QSOs, especially when compared to the percentage of satellite QSOs I've made via AO-51 before its recent demise that I recently wrote about, but I enjoy working SSB via satellite as much as I do FM.

So, VO-52 is either broken or pointless?
Why would you want to lug around so much equipment to work a satellite? Not to mention the difficulty in aiming such a sharp aerial at it - you'd need a computer-controlled rotator. And if you're going to have to sit in front of a computer to make a QSO you may as well use Skype.
