I read the article, I don't remember all the freqs off the top of my head sorry. I have since looked them up, thanks for your help.ka3jjz said:Clearly, you have not read the ARRL article; it tells you all about what is necessary; uplink freqs, what is Doppler shifting, and so on.
Working the ISS in repeater mode is only possible when the astronauts command the Kenwood into that mode - I don't know whether they've done that yet or not. More than likely the Kenwood is probably in digipeat mode.
I know of at least 1 ham that's worked the ISS with an Arrow antenna and a HT; and another, a well known MT writer, has done it using his mobile 2m radio during a high pass.
So it can be done with relatviely simple equipment. 73s Mike
