Just to clarify, the downlink is 145.800 and uplink is 437.800? Is there a tone. Someone posted the wrong uplink frequency I think and I just monitored a wonderful pass with lots of great signals heard in FN21. I was unable to hear myself and suspect I had the wrong uplink frequency. Thanks for clarification 73 Rick, W2JAZ
The official uplink frequency is 437.800 MHz. However, it has apparently been configured to repeat the Tomsk satellite, with an uplink frequency of 437.050 MHz.

There is no tone. The thing to remember is this is not being turned on for random contacts. It is setup to retransmit one of the student sats that was recently deployed by hand from the ISS during a Russian EVA. That sat transmits on 437.050 and that is why the uplink is 437.050 and not the "normal" 437.800 that is published as the repeater frequency on ariss.org for example.

So, if we use the repeater, are we competing (interfering) with the student experiments? Or, is that only geographically related (i.e. over Russia)?

I think TOMSK just sent recorded messages "greetings to earth," but Tanusha 1 and 2 also try to make an autonomous digital network, I think on UHF. If the network is only on UHF or transmissions on 145.800 would not interfere with them (i.e. they also use VHF for the network but nothing close to 145.800), this shouldn't be a problem.

Yes, using the radio as a voice repeater does interfere with the intended use. The Russian team set this up at the last minute because they were concerned about getting telemetry from their satellites, which might be spinning more than they had expected. They are hoping the nearby receiver on ISS can capture and retransmit telemetry that is not being picked up on the ground.
I do not know if this applies primarily over Europe and Asia, or if repeater use is a problem everywhere. I would guess that the satellite teams would appreciate receiving telemetry from anywhere it is heard. There might be something on the satellite websites about that. I am not directly involved.

ISS crossband repeater seemed off on 2043 UTC pass over NA. Digipeater was on though.
