Hi All, I just uploaded two new files of the radio that I plan on building next. Please take a look and tell me what you think about them. The radio is based...
I was wondering if anyone on the MOPAGROUP or the REGENRX GROUP was considering starting to supply some KITS for tube transmitters or receivers? There was some...
Can you tell us more about the NoGa Twin-Tube transmitter based on a kit by Mike Branca, W3IRZ I haven't heard about this that I can remember and would be ...
Toroid final tanks have even been used in the final amplifier stages of some commercial transmitters. For example, the Dentron linear amplifiers back in the...
I Philately reject this argument! ... and involves the participation of some of the largest financiers in history, not to mention devotees of the past, little...
Greetings, I was able to make one contact on 80 meters Saturday afternoon using the Ten-Tec Regen and my 900 mw scratch-built solid-state transmitter. It uses...

... Hey Brian, Unfortunately Mike is now an SK. I got one out of his last batch of Twin Tube Xmitters about four or five years ago. There is some information...
In this vein, it may be worth asking George, G3RJV if he would be willing to provide another run of Solid-State SuperGainer kits like the ones he provided at...
I agree. I'm still kicking myself for not getting one of George's kits at that FDIM. I would also be interested in either the DesertRatt II or III. Gary's...
Wow - THIS is a very comprehensive site: http://www.electronics-tutorials.com/receivers/regen-radio- receiver.htm I like your implementation of the Kitchin...
Couple days before Christmas, my son who is 9 years old, was very restless. I gave him a challenge to keep him busy. I asked him to build a Morse key out of...
Howard, that kit was by definition a regenerodyne, which is one of the best simple regen circuits going. Curious what his regen detector actually tuned. I ...
The 6AU6A should work as an oscillator tube, and the 6BQ6A would make a decent amplifier tube for a MOPA design. The 6DX8 is a High-Mu Triode - Sharp-Cutoff ...
With the parts he provided, the detector tuned 8.125-9.342MHz in my kit. I had to pad it to tune 6-6.43MHz which was his target range. This combined with an...

Hi All, I got some slow motion dials and coils from ebay. The coils are not like anything I have seen before. They are like the varometer coils where you twist...
I have seen some like that before, where the twisting inner link is left in a fixed position once the correct position has been found. I am not sure what they...
Well, I stopped by the venerable SkyCraft and picked up some "real" LM380's. I replaced the "SP"380 I had on my breadboard with one and VIOLA!!! I got a...
Tracy, When I looked up all the "380" info I could find, I did not find reference to SP380's. I figured as you did, that it was just another manufacturer's...
I think the SP380N is electrically the same as the SP380A. If so, it's a quad 2-input NOR gate. Some distance from being an audio amp :) (The reference was a...
Ian, Thanks for that info. This makes me think that the SP380 is a very old chip and seems like I do remember somthing about this series, from a long time...
Hi All, Does any of you know how to wind / re-wind a RF Choke to make it a diferent value from what it was with out the use of a meter that can messure the...
Hi Corbin Do you need to reduce the inductance or increase it. A very rough rule of thumb a 1mH choke reads about 10 ohms on a Multimeter. The best way is to...

Tony, I need to increase the inductance from 100uH to 2.5mH and then on top of this wind another coil for a G W Short radio design. Corbin ... Multimeter. ... ...
