Using APRS and UI-View to Determine a Tropo Opening

Original Post on PropNET Studies March 27, 2012

Hi all,
How about some 2-Meter Tropo.
I am a longtime 2-Meter SSB operator (early 80's). I have over 200 Grid squares and 43 states using CW and SSB.

I noticed last night that there was a large Upper-Air High Pressure ridge over us, so I unplugged the PropNET rig and plugged in the FT726R and UI-View to see how good the Tropo was. Not too bad. This is the time of the year to be on watch.

The maps tell the tale.

First is a normal map.

This is the early morning map with the Tropo well evident.
