PHOTO OF THE WEEK, Project Complete

[Jack Schmidling]

My homebrew project is now on the air. 8000 modulated by a pair of
813's driven by the Ranger.

Those within range are invited to join the Noon Time Forum on 3875
weekdays at Noon, Chicago time.

Jack, I really enjoyed reading your writeup and looking at the photos.
You have a wonderful one-of-a-kind transmitter there. It looks great.
Hope to talk to you on the air one day. 73 de Randy, WB5KCM

Really nice, Jack. Did you use the Ranger audio system to
drive the 813s?

Such a project is never really "finished", because there are
always new ideas and parts to be tried out.

Roger. I started a thread earlier on using 813's as triodes and it was
like falling off a log. The modulator consists of a very small chassis
with a fil trans, tube sockets and a meter. This sits next to the mod
iron on a wood deck. I like the idea of the mod iron isolated from ground.

Roger again. I want to eliminate the Ranger for one thing starting with
the audio. I bought a 4W audio pre-amp and when I get tired of playing
with the new rig I want to see if this will drive the 813's. I need
some ideas on interfacing the two... some sort of interstage audio
transformer I suppose.

Then, a simple xtal controlled exciter would be fun.

No end is there?
