Those headphones seem to have lots of negative reviews. Sound spectrum / range seems limited.
Unsure how I’d get the headphones apart and rebundled to run off direct DC plus pipe the audio out to the audio input on the AM transmitter. Seems like quite a bit of complexity and likelihood for breakage is great.
Considering how wire runs tend to go around here, my run from the mixer (in basement in building next door) to the transmitter (on top of other building) — the run is rather long.
Have about 75 feet across to cover, another 40 ft to rear of structure then probably another 15 ft vertical plus another 10ft to reach the transmitter. Probably in 125-150ft range total. Line losses and drops are a concern at that length (maybe I am being overly worried there).
Comparatively, the FM transmitter route seems way shorter. I can go out of the basement where the mixing console is and up the side of the building and put the FM transmitter there where possible that the top of the AM antenna would be in line of site of the FM transmitter although some 40ft roughly apart. Cable run would be 15ft interior plus 20ft vertical exterior for 35ft approximately. That is more reasonable.
Still dealing with building holes and need to ground and lightening issues.
In ideal world we’d do a FM transmitter in building to FM transmitter outside to FM receiver coupled to AM transmitter.
