Ok, the antenna on the 20 meter radio once was a Cushcraft R8. Since it
no longer loads on any band who knows what's out there now.
Copy on the test was at best 30%. There is a station running mark on
"our" space frequency and it's about 10 db above the net. When he
comes in we get wiped out. Welcome to 20 meter RTTY ...
Enjoy!
