Twinplex Regenerative Receiver part 2

Today I got  the chores out of the way early and started punching holes in the back of the chassis. There are quite a few for all the parts that are going to be installed back there. I try to group the power cord, fuse, switch, and transformer close to allow the shortest wire runs possible. If you think ahead about where everything goes you won't have to go back and touch up paint. (not that I have ever had to do that... Ahem cough cough)

 Here is a view of the chassis with the holes drilled today. Somehow I lost my socket for the Hammerland 6 pin coil form. So here I go on a hunt for another...

The Green Hammer-tone paint came out fine on the chassis front panel. Letting it sit in the sun before spraying seems to help the process along. In the background you can see the power supply for the 6L6.
More to come....

Twinplex Regenerative Receiver Build

I started today on the Twinplex Regenerative Receiver. The parts have piling up since my friend James told me he found a good receiver design to build. He has gleaned great results with his and says it is a hot little receiver. (good enough for me)



Here is the box  O' Parts. Those Big knobs are vintage NOS I picked up very cheap. I did buy some more of the cloth covered wire from  http://enginebarn.myshopify.com/   
No affiliation. I just like the product.




After some tedious measuring and layout, I finally found a layout I liked. Let the drilling begin....

 The front panel holes are in place, now for the chassis front hole placement. My drill press is just big enough to be able to mark (with the drill bit) the chassis with the front panel still attached. This means all the holes will match up perfectly.

 Here is a view of the parts for the front panel dry fitted to the chassis. Everything lines up perfectly so the front panel is now ready to be painted. The paint of choice is going to be hammer-tone green. Green you say? Yep green...(Is it starting to look like a radio yet?)
 More to come...

Old US Army Morse Code training film.







Old training video.

Thunderstorm, Rain and Morse Code from Bug (MP3)

Thunderstorm Rain And Morse Code

In the MP3 link above I really like the mix.Here is the story that goes with it:

In the middle 1980s, former United States Coast Guard Radioman and well known radio amateur, Edward A. McCarthy was tuning the 7.0 MHz amateur radio bands at his amateur radio station in Florida when he came upon a conversation between two amateurs using continuous wave (CW) Morse radiotelegraphy. Since a tape recorder was nearby, he decided to record the conversation between David J. Ring, Jr., N1EA/MM (Maritime Mobile) who was sailing as Radio Officer in the Merchant Marine on the coast wise tanker "SS KING" run by American Heavy Lift Shipping, Inc. of Houston, TX. The SS KING was in the middle of the Gulf of Mexico having sailed from Corpus Christi, Texas two days prior and another local radio amateur who was getting on the air after a long absence.

Mr. McCarthy, W1YT sent this recording directly to the "SS KING" where Mr. Ring was so overjoyed at the quality, he decided to improve on it by making a recording of storm and rain sounds and mixing the Morse code together with it.
