[amsat-bb] ISS APRS Signal Quality?

[Brian Clark]

It appears that after the system came back after being down for over a
month, that something changed.  I have been able to hit it with a Kenwood
TH-D72, but it was not easy.  The receive is a bit deaf, and the transmit
is very weak.  I tried last evening, but was unsuccessful.

I am wondering if some new antenna systems are being tested.  It was a
similar situation with the SSTV event over the weekend, then it came back
full strength.  I am certain that after the testing is complete (if that is
what is going on) things will be strong and great again.  The A.R.I.S.S.
Team is very good and is always working hard with the ISS crew members to
keep the systems in tip top shape.
