“Don’t some Part 15 AM transmitters already include a gas discharge, transient protection device just upstream of their r-f output connector, and after their internal loading coil?
“Just curious. then, as to why RFB suggests that an outboard device such as the “polyphaser” installed downstream of that connector is a great choice.”
I think it’s obvious Mr. RFB was talking about transmitters lacking the gas discharge device, which would be the majority of transmitters.
Just prior to that post member rich wrote:
“So, if such a protective device is installed in the path from the r-f ground (chassis) connection of a Part 15 transmitter through any long, conducting path leading to a ground rod (or similar), that protective device will NOT de-couple such a path from radiation during normal operation of that transmit system.
“This may be of concern to those who want to comply with FCC §15.219(b).”
You can get back to your enforcement check point in a minute, but I happened to read over on another site that you have owned a part 15 FM transmitter that was subjected to a compliance field test and found to be obedient.
It would be interesting for the audience here to learn of that experience, and a description of the model involved.
