Thanks for the reply Neil.
The power that I have available in the barn loft is tapped from a light bulb so there no third pin ground. How do you think I should configure the rf choke pins on the SStran?
I am hoping to have some time to play this weekend. Do you think that an 8′ copper pipe would radiate better than a wire? (I guess that one is easy to answer…) Do you think the SStran can tune to it acceptably without the circuit mods? The roof itself does not appear to be grounded. How would it change things if I ran a ground strap from the edge of the roof to a ground stake? I guess I should do some checking of the different sections of the corrugated roofing to see that they electrically connected. Now I just need to figure out how I can mount an insulated pipe in the center of a sloped metal roof barn without spending money!
I know that some of this might now be in total part 15 compliance but I am not worried about that since I don’t plan on doing any consistent broadcasting and have only a few neighbors that could possibly be in range under the best circumstances. (I sometimes drive a few miles over the speed limit too but not enough to get stopped if you get my drift)
I spent 20 years in the Radio business mostly in programming but did some engineering too so this really is just for fun. At the same time, I really believe that the FCC needs to address the issue of low power broadcasting in a way that allows the average, responsible citizen to have access to an easily licensed way to serve the community even if it takes on a commercial stance. The AM band is such a dinosaur of radio these days that a low power (but usable) service would present absolutely no threat to the commercial conglomerates that have homogenized radio but would allow some programming diversity and actually local service!
Thanks for all you folks do!
