The ISS cross-band is usually 145.800 MHz down and 437.800 MHz up. Of course that doesn't meant that it can't be something else.
I note however, that 145.990 MHz x 3 is 437.970 MHz. Could you be hearing the 3rd harmonic of your own TX?

Hello to all.
Yesterday i posted to say that i heard the crossband repeater active some other hams pointed out to me, that the ISS was active on packet at the same time.
i also noticed that my signal report was removed from issfanclub.comovernight.
There was another late night pass that i could prob have worked, but it was during my sleep time :) so i didnt try then.
I have just tried again now, and found it to be active. 0640hr utc pass over VK1.
so what is the story?? i could hear myself.......... but only when the ISS came into view... so it wasnt an operator error.
I understand that this mode is experimental, with 145.99 uplink and 437.800 downlink. This mode seems nice, as i dont need high power or big antennas to get in.
Can the equipment on board support both modes at the same time? And is anyone interested in trying a qso with me on future passes? next pass is low elevation for me (approx 15deg) so should be workable for a little bit. due at 0820hrs UTC (thereabouts)
nothing much else usable till tommorrow, and i read Kenneth's notes about the EVA, so it might be off soon anyway.
thank you all in advance. Darren VK1HFC
