Homebrew: The N1TEV Regen Build – Part 1
Today I picked up some parts to start the build of my N1TEV regenerative receiver. Checking online I found that Far Circuits makes a board that is ready to go for this project. His website and ordering process are definitely old school. He really needs to make a better e-commerce web site. Basically ordering from Far Circuits sucks, but the boards are nice and I picked up two of them. One for Jeff N9IZ and one for myself.
I went by RadioShack today to get some of the parts. I couldn’t find all the parts locally, so I had to scavenge about a bit and look for some parts that I had lying around the shack. This ended up to be a good thing, because I had several of the capacitors lying about. Like a mondo 100V version of a .047 uF cap that really just calls for a 50V small cap. The legs of that cap were a bit thicker since it can handle double the voltage, so I had a bit of a struggle getting through the holes on the breadboard. RadioShack is really pretty expensive for parts, so if you have bits lying about I would suggest you use them.
I would say that I am about 40% done with this project. It took me about an hour to do this much, and that was with the scavenging about to find some of the caps and resistors. I had a blast soldering these components to the board. It was nice to smell the familiar scent of rosin and solder again if just for a little while.
On the plus side I found a great site to look up resistor color codes to find resistor values here. It is very simple but effective. I found another site that will tell you the values for those small disc caps on Elecraft’s page here.
Looks like I’m going to need more parts that I don’t have lying about so off to the internet for those. I need a variable capacitor, a good enclosure, knobs and miscellaneous goodies still. Jeff (N9IZ) sent me a link for a site for some great vernier turning dials that I think would be awesome for this project.
I plan on using a BNC connector for the antenna connector. I think that would be a good solid choice and I have a chassis mount one of those around I think.
RadioShack did not really have anything good in the way of enclosures so I stopped by another electronics store in town called Lafayette Electronic Supply, Inc. They have a great selection of stuff, but holy utility belt Batman are they EX-PEN-SIVE!!! The enclosure I liked was $40. $40!!! can you believe that for a empty metal enclosure? I thought that was just way too beaucoup expensive for that and will either look around online or make one from copper clad boards which a lot of people have done building regens like this. I walked out of Lafayette Electronic Supply without buying a thing. For the prices they charge there you would have to give blood or take out a loan to build something. I could have bought 4 AM radios for the price of the enclosure alone. Horsehockey! as Col. Potter once said.
The build was fun, but all good things must come to an end, at least for today. Stay tuned for Part 2! I’m really having fun building this and it is going to be awesome once I get to hear my first scratchy reception of a HAM or SW broadcaster.
