Hello fellow HAMs, I am new to this hobby so I have a few questions ...
1. I have an "ADI AT-201" radio and I tried to listen to PCSat at 145.825 MHz and shortly after Hamsat at 145.90 MHz, but failed. I was outside at the time www.heavens-above.com specified, but all I heard was noise. So my question is: What was I supposed to hear? What did I do wrong?
2. Is it possible for me to listen to ISS with "ADI AT-201"? The frequency is 145.800 FM, and I don't think the radio can reach FM frequencies, right?
3. If I can't use that radio for ISS, what should I do? -- i.e. what radio should I get?
Thank you very much.

Hi!
Taking your questions, one at a time...
> 1. I have an "ADI AT-201" radio and I tried to listen to PCSat at 145.825 MHz and shortly after Hamsat at 145.90 MHz, but failed. I was outside at the time www.heavens-above.com specified, but all I heard was noise. So my question is: What was I supposed to hear? What did I do wrong?
If you hear anything on 145.825 MHz, it will probably be data and not voice communications. As for 145.900 MHz, the "Hamsat" (also known as VO-52) does not operate in the FM mode. You need a radio that can receive SSB or CW in order to hear that satellite.
> 2. Is it possible for me to listen to ISS with "ADI AT-201"? The frequency is 145.800 FM, and I don't think the radio can reach FM frequencies, right?
That is the frequency. Much of the time, you'll hear "packet" - data - on there. Sometimes, there will be voices (scheduled contacts with schools, or the crew making contacts with ham stations on the ground).
Being in the USA, if you program a memory channel with 144.490 as the transmit frequency and 145.800 as the receive frequency (or 145.800 with an offset of -1.31 MHz), you will be all set to talk with the ISS. For packet, you can set it with a transmit frequency of 145.990 and receive frequency of 145.800 (or 145.800 with an offset of .190 MHz) and either a TNC or packet software for your computer with a sound card.
If the ISS cross-band repeater is turned on like it was just after Christmas, you'll only be able to hear it on 145.800 MHz. To transmit through it, you'll need a 2m/70cm radio since the repeater requires you to transmit on/around 437.800 MHz.
> 3. If I can't use that radio for ISS, what should I do? -- i.e. what radio should I get?
As I mentioned above, you can use that radio to hear - and possibly communicate - with the ISS. If your interest is also in other satellites, you will need a 2m/70cm radio at a minimum. There are 3 satellites that can be used with a dual-band FM mobile radio or handheld, and others that require SSB or CW capabilities.
Have you visited http://www.amsat.org/ yet? Or for the ISS, http://www.rac.ca/ariss/ for more information?
Good luck and 73!
