[amsat-bb] ISS Crossband repeat mode off, packet digipeat on

[John Brier]

I'm doing an ISS ham demo for a friend's son who is on the autism
spectrum on the 2020-10-07 - 2348 UTC pass. He is obsessed with ISS
and space. Apparently he knows the gravitational force of most of our
planets. ISS will be visible at -4.4 magnitude. 81 degrees max
elevation.

My primary goal is to demo SSTV reception. In between SSTV image
transmissions I will try to make a QSO on the digipeater, get a beacon
through, or at least receive packets.

I will be using my Kenwood TH-D72 and feeding audio to a laptop. On
the laptop I have RX-SSTV and UISS. I will not be using UISS to
transmit packets, just to show received packets to my friend and his
family.

Therefore, I will use the built in TNC on the TH-D72 to send packets.

I'll be in grid FM06 if anyone needs it, instead of my home grid of FM05.

73, John Brier KG4AKV
