AM transmitter build - by Tim
#18

(03-09-2018, 12:37 PM)TV MAN Wrote:  I have been studying the circuit Sam posted and I can see several things l like about it. One in particular, and that is the tuning cap is not connected to B+. That had bothered me, since that is a pretty large part to have that kind voltage on it. Then, there was the isolation issue. With this circuit, the tuning cap can be mounted directly to the chassis to ground. Really simplifies things. I am mocking up a potential layout.  I will post some pics of the idea and see what you all think. I want to avoid feedback, hum and noise.

hey tim
I checked .could not make it hum or buzz
I don't have an antenna I either put wire post to post.  or far away still picks up good or it I touch
transmitter post and it comes in loud and clear .
only if I put in kitchen it gets static 

sam

Some day, and that day may never come, I will call upon you to do a service for me. But until that day, accept this justice as a gift
