I need help with the fm frequencies I found online for the ISS and satalites I track with the ISS tracker on my android phone. I just purchased a Arrow Antenna, SAT antenna, at Orlando. I have yet to receive a transmission from the spacecrafts. I hook the antenna up to my Yaesu FT-817. It puts out 2.5 watts on battery power. Here are the frequencies I use:
Lapan-A2 435.880 D, 145.880 U.
Fox-1A ( AO-85) 145.980 D, 435.180 U.
AO-27 435.795 D, 145.850 U.
SO-67 435.345 D, 145.875 U.
HO-68 435.675 D, 145.825 U.
SO-50 436.795 D, 145.850 U.
BY 70-1 436.200 D, 145.920 U.
NA1SS ISS 145.800 D, 437.800 U.

Please help me out as I am just starting out in this. Let me know if I am making a mistake with these frequencies. Many thanks to all.

Thank you W1VT, trying to figure this out was driving me nuts.

Ok. I am stuck in chapter 4 page 4-4 of the current ' general class license manual'. I don't understand the 'calculating a power or voltage ratio from db'. How does log negative 1 get figured in log10 or log20 to result in the answer for example 1 and 2.
I have a casio fx-300ES plus. I tried the inverse method also. No luck. Please help!!

Tried to contact you the other day. I don't think that my antenna is strong enough. I am using a buddipole antenna. Awesome antenna but I am not sure I am reaching MS.

Congratulations. What repeater are you near? Send me the frequency and ctss tone frequency. I have my Tech license as well and am working on getting my General soon. I want to see if I can reach you. I am testing out my new portable antenna.
