Winlink 2000 Email As A QRP Buddy

Playing around with QRP is lots of fun and sometimes very challenging. But, it usually takes two to tango. You need somebody on the other end of the link to hear you and respond. Usually, we expect that to be a warm-blooded human being. If you have the itch to play radio with QRP and nobody is around, well, you're stuck.

There is another way....

Recently, I acquired an account on Winlink's Global Email System and can now connect to servers around the world and the country to send email via HF radio. It occurred to me that I am connecting to a computer that is, for the most part, impartial in it's judgement of my signal quality. If it doesn't like it, it won't answer. If it is too weak, it will not hesitate to dump me and move on to paying customers.

I use RMS Express as the client software for Winlink. It works well for my purposes. Within that software is a database that shows the available remote stations that you can connect if you have a Winlink Email account. The database shows the distance to the station as well as the expected propagation characteristics.

The table below shows some of my results using QRP power levels:

These results are not record breaking but I am just getting started.
