Rick N3FJZ has stepped forward and is building the direct conversion receiver that Dean and I have been working on. This will be big help in our testing of the receiver. See above for the video report on his build of the PTO stage.
When I saw this, I found myself thinking two things:
1) Those really are "rigs."
and
2) I am not alone!
Years ago, I was having a tough day on 40 meters. The Waterfall Policemen were gleefully attacking my admitedly less-than-perfect SSB signal. Unbeknownst to me, someone out there was listening, and listening with a homebrew receiver. A receiver with a PTO. It was Rick N3FJZ. He made my day when he sent this video:
Here are the other blog posts on the amazing rigs of N3FJZ here:
More to follow, both on Rick's receiver and on the work of other intrepid builders.
Thanks Rick.

Be interesting to see if it is possible to tame. Seems overly coupled to the buffer. I have always had good luck with a very lightly coupled jfet Hartley and bipolar buffer.

ReplyDeleteBeen admiring Rick's work, his superhet two band transceiver is one of the most complete homebrew SSB transceivers I've seen. And it sounds amazing, he has obviously taken care to get every stage working just right. Kudos Rick N3FJZ.
