Re: [IRCA] Synchronous AM Boosters Could Help Revive Senior Band

2017-03-24 Thread Russ Edmunds 
It should probably be noted in this discussion that synchronous AM
transmitters have been in use in Europe for decades on the AM band. There
were and are various mixes of low power and low and high power AM's
operating on the same channel with the same programming. Back in the 1970's
there were a greater number of groupings of low power ( 250-1000 watt )
stations in the UK and Spain in particular utilizing this method, and in
many cases those signals would be audible under good TA conditions here in
ECNA.

Usually, these sounded very much like a single transmitter here. Whether
this was because we heard only one station ( the most powerful the highest
antenna or the most favorable tx location could be debated ) or whether the
synchronization was that good is impossible to know some 40 years on.

Based on this, plus the ( unmentioned in the article ) synchronous WBZ/WBZA
experiement with newer technology which remained into the 1960's, as well
as the KOB/KKOB setup in NM, plus a few others, there shouldn't be any
reason why this wouldn't be a viable option technically.

That said however, the low cost of erecting and maintaining an FM
translator is probably a momre cost-effective solution.

Not only have those towers been dismantled, but the building and most of
the entire complex has been removed. The towers were about a quarter mile
from my yard when I was living in East Springfield. I could see them out
the window when I was sitting at the kitchen table.  Jim

Are the two WLLH-1400 transmitters still synced? It would be interesting if 
those of you living around Boston shared your experiences with them.

A really interesting article; I enjoyed the description of how the 
old WBZ and WBZA were locked together over a phone line. Plus, it 
features a Scott Fybush photo.   Can't ask for more than that.
