We have a big AM that is simulcast in two adjacent markets with FM translators. This is a spoken word formatted station with mostly ministries, not unlike Mike's station in Omaha, so no musical programming.

Both translators have been run in mono since I put them on the air. In both market, they are the only translators that are in mono and I think it helps substantially in making the signal more usable, especially outside of the 60 dBu contours. I am constantly sampling and comparing on a variety of radios, and for us, it's not even a close call. Making the decision for the receivers, in staying in mono all the time, is definitely worth it. If I had a Class C, I'd probably go stereo however.

My first FM was mono.  Never went stereo.  Listeners appreciated the difference in fidelity more than stereo.  I still try to switch lower powered stations to mono when there is ice on the antenna.  Helps bunches!

Practically all auto radios and many others have an auto blend to mono for weak signals.   This cleans up a lot of the stereo noise.   Your studio monitor probably has no auto blend to mono, especially if it’s the audio output from a modulation monitor.

Thank you for that input, Mark.  I neglected to include the fact that we run both our translators as mono.  We are laboring under what we think is true, that running in mono will clean up noise level in marginal signal areas.  Have an auxiliary FM that runs in mono and it makes a big difference in the studio air monitor compared to stereo.


Willing to listen to contrary arguments about the mono/stereo thing.  I find it is not without issues on the translators but not so much on the FM Aux.

I am not taking care of any ministry stations on AM, but have some commercial clients that are AM stations. A mix of those with and those without translators.

The stations with FM translators broadcasting their programming, in stereo, have basically become small FM stations with an AM connected. In my smaller markets it's been just great for everybody who has one.

We're doing more applications in the upcoming January filing window, for some Class B stations that were not eligible to apply the last couple of times.

Pretty good results in Omaha, a place where I, too, thought we had too much RF for this to work.  There was a class A at the same general site that the TV stations and the big FM stations use that was not receivable, by me at least, on a Sony SRF-A100 AM Stereo/FM Stereo portable radio.  The FM front end on those is notoriously bad however.  Not up to Sony’s usual standards. 


So I didn’t think translators would make a dent and while I still have difficulties hearing anything on some on home/portable/table type radios, in-car radios are a way different story.  We have two translators, one 250 watts and another 60 watts at different sites, both “relaying” AM programming.  On one translator (250w) the signal is so good, we use it’s frequency first in positioning the station.  It far outperforms the AM which is severly challenged anyway.  On the 60 watt unit (400 ft.), it covers half of the city well, not so much the farther half but then as you travel further away into the next county it comes up again.  The AM it relays has a pretty big daytime signal but at night has less power than the translator!  (54w/60w)


We know of at least one individual who was reached, along with her family, for Christ by the 60-watter.  That one was supposed to be 110 watts on another frequency but we were beaten to that frequency by a hair’s breadth, so it wound up on a different frequency that put it right next to the local hip-hop station.  That’s what caused it to reach that individual.  We would not likely have reached her on the channel WE wanted, but God had other ideas.

Anyone have pro/con of having an FM Translator for an AM site? Seems like something to jump on if you have the opportunity.
