Encouraged by a post on a forum that I visit, I decided to have a go with WSPR (Weak Signal Propagation Reporter) whilst I was working in the shack yesterday.
I set the 857 to 10W output on the 20M WSPR frequency (14.0956) and adjusted to audio input to give 5W total output.
Here are the results…
Not bad with 5W into a homebrew doublet.
