I've used 437.500 as the center uplink frequency on the three PO-101 passes that I've worked to date. On all passes, I was able to get into the bird with 5W or less. On the second pass, I had the bird all to myself, and I was able to get in well with 0.5W, at least with no competition.

On the AMSAT FM Satellite Frequency Summary it lists the up-link frequency for PO-101 (Diwata-2) as 437.500 MHz. On the PHL Microsat website, the up-link frequency is listed as 437.7 MHz.?? Which is correct??? I tried to work PO-101 during Field Day yesterday and had no success getting in with my radio set to 437.500 MHz, and Doppler-shift adjusted near values.?? Of course, being Field Day, I could have just been 'out-gunned'. I do wonder, though.
