Another option would be for packets on ISS to be on 145.825 always. That has historically been the channel for AX.25 digipeating:
We hope to establish that as a permanent fixture in space with all satellllites that are capable of digipeating being on that same frequency so that access becomes transparent to the users.

Could the two channels used for casual crew to ham contacts (144.49/145.80 & 145.20/145.80) be programmed to send a subaudible tone?
The subaudible tone would only be on the downlink from the ISS and not required for uplink stations. Let me be very clear on this, I am not asking for the subaudible tone squelch to be turned on at the ISS,
subaudible tone encoded into the transmission from the ISS on 145.80 and only on the two channels used for crew to ham communications.
The subaudible tone would not be sent on the packet repeater
(145.99/145.80) or other channels that use 145.800 as the
This would allow those of us who would like to monitor 145.80 for contacts with the crew to set our own receiver subaudible tone squelch. We then would only hear signals from the ISS when a crew member was
contacts. The squelch would not open for packet, etc.
For those who want to hear everything, nothing would change.
