[Ground-station] Upcoming channelizer test opportunity

[Mike Seguin]

Hi Michelle,

Could I get a bit more explanation of what you want to test?

The North East Weak Signal Group (NEWS) gets together in a few weeks 
(7/13) for our annual picnic and MDS/ERP testing. This year we will test 
10/24/47 GHz. In the past we'd also test 78 GHz, but we found we run out 
of time!

We have quite a group of stations that get together. Pic from 2016 of 
the 47 GHz testing attached. We had seven stations that year on 47 GHz. 
It keeps getting bigger.

Mike
