... I am again disappointed to learn that random unscheduled contacts are still uncommon ...
Well, the astronauts are quite busy up there ... (grin)
That is what makes the scheduled amateur radio time so exciting - like last Field Day when we were able to make voice contacts ... Heck, I used just two Watts and a handheld tape measure beam for my contact ...

And, of course, monitoring hams should never try to interrupt or contact during any of the scheduled ARISS contacts.

haha. I know, I should be grateful too. I am, but I'm also upset! I can be both right?
Anyway, I'm hoping they can organize another field day operation this year. I haven't been to field day in years anyway, so my first in a while plus my first ever ISS contact would be amazing.
fwiw, I do know not to interrupt during scheduled ARISS contacts. I was telling someone else who responded to me that it was a good thing they don't publish the uplink frequencies not only so people don't intentionally try to take advantage of the situation, but also so ignorant (and excitedly blind people like me) don't interfere.
Thanks for the links, and for your website and work. I can tell you put a lot into it. BTW, I'm a Kenwood guy and considering a new dualband HT for satellite FM work, and I saw you said the TH-D72A was the only HT that did good/real full duplex. If that's so, what do the other radios do? Do they get desensitized or something?

Sorry if this has been asked before, but are not the uplink frequencies 145.20 for region 1 and 144.49 for regions 2 and 3? Or do they use different uplink frequencies for scheduled contacts?

Info on frequencies here.

I think they also have a backup frequency that is not published. They have had interference on both uplink and downlink in the past possibly accidentally. The exact time of school contacts and normal downlink frequency is usually very well advertised in the country where the contact will take place.
Sometimes, including one recent contact in Italy they actually re-attempted the contact at the next pass 90 minutes later as there was interference. They try throw lots of power and gain on the uplink in an attempt to drown out any accidental or low power interference.

Here is an exciting ISS project hopefully happening this weekend - another set of SSTV images being transmitted. Details at ...
