I got my version of the ET-1 transceiver working. As I described in previous posts, I first got the transmitter and the receiver working separately, each with their own J310 FET (oh the extravagence!)<\/b> Then I built a switching arrangement that allowed for just one shared FET and very short leads. I used a 4PDT “push button” switch from an old Ramsey Electronic LC meter. See the last picture for details. I use the tube from a pen to operate the switch (that’s the green thing in the picture). <\/b><\/div>\n

It is inhaling and exhaling. My 20 mW signal is being picked up on the Reverse Beacon Network, mostly in New England, but today in North Carolina. <\/b><\/div>\n

No contacts yet. I may have to resort to scheduled contacts. OM Yingling W2UW was operating during much better propagation conditions (2001), so I don’t think I will ever get close to his impressive (23 states!) operating record. <\/b><\/div>\n

<\/b><\/div>\n
But it has been fun getting this thing going. The N0WVA regen design<\/a> is one of the best and simplest regens I’ve ever built. It is really nice –hardly demonic at all. <\/b><\/div>\n

<\/b><\/div>\n
I can run the whole thing off one 9V battery. I think it is a cool looking machine. <\/b><\/div>\n
