You're a wildman Don !
You might be right. I run stuff like this daily. ;>)
I like that, very cool.
I just fired mine up on 7050 and tested it on CW. I didn't have any 12au7 s so I used a 12bh7. Power out is reasonable . Better then I thought it would be. Now to find a mic. I hope I built the right rig! Mine is on Red Cedar (BBQ planks) because I am a bit of a redneck I guess.
Today I got the modulator working. Mod % is a bit low but that is probably something I did wrong as I can get too much gain in the second stage of the Audio amp so I must not have enough in front of that. However it works so hopefully I can get there from here. Has enuf power with the 12bh7 but I ordered the proper 12au7 tube anyway cause I wanna know.
I have it working now. No one nearby to talk to but it appears to be ok. Now I will see how many errors I made. Or even if I built the right circuit. Whatever I am still very interested. Can't wait for tonites video.
As per Bobs instructions on this weeks video I called International Crystal to order crystals. They are no longer selling crystals, will not take an order.
Does anyone recommend a source for the crystals Bob specified?

I use AF4K Bry Carling in Florida. He has originals FT 243 style or new smaller ones in the vintage cases. He is one of the prime movers in the Novice Rig Roundup event (NRR) and is a very active ham op mostly in CW usually around 7120khz. I have bought many rocks from him over the years.
BTW those are only suggest freqs or traditional AM window. I am using 7145 approx as it is relatively quiet and I have the rock in stock. I would rather edit my old post then add but dont have that option now with this old post so sori.
