And now back to normal.
Lots of folks are running unattended beacons on 145.825, which can cause QRM to
HO-68 FM users. I only decoded about half of those heard:

Any chance we could get the ISS to change their packet frequency?

No,
The APRS QRM'ers with their unattended beacons are the problem. Years ago
I said APRS was bad, but I never thought it would ever get this
bad. Thi
Bob,
145.825 is the "established" space APRS frequency, and has been/is used by
more than just the ISS for years. There are other APRS satellites which are
intermittently active on the same frequency, and I expect there will be
others in the future. I can't address the formal coordination issue,
No one 'owns the frequency' and if in-place coordination can not resolve
the issue, the newest user should consider moving out of the required
bandpass. Was the first user ever coordinated? ~~Larry W7IN~~

Alan,
I agree with you totally. It is going to be an ongoing problem and unless
individual operators take responsibility for their emissions
My 2 cents:
A.
I like to have MORE APRS satellites, like PCSAT, RAFT, ANDE, ISS.
To my best knowledge we do not have an alternative for such services.
B.
We do need to improve the usage / behaviour.

- HAMs using 2 second interval beacons ( !! )
- HAMs abusing feat
