Thread-topic: [CRTech] FM Translators

These are AM on FM translators so there is no baseband.  They get direct feeds from the studio. 


The “not real world” receiver being used for an air monitor is a ROLLS that is probably 10 years old but I don’t think any older.  We have 3.  The one listening to the one translator about a mile away is very happy with it.


I have a Bose radio in my car which doesn’t seem to like the mono audio at least without a stereo pilot.  It has no problem with the way-out-of-town auxiliary but the in-town translators drive it into distortion for some reason.  Only radio I know of that exhibits that behavior.  The ROLLS doesn’t and the chief’s in-truck radio doesn’t. 


I honestly didn’t know about them using DSP these days and I still have some radios from the 80’s (and one from the 70’s) that get fairly regular use!

Simple cure is to take a feed from the baseband monitor which would be a mono output

You say your auxiliary FM has noisy stereo on your studio air monitor.   That monitor most likely has no “blend to mono”, so it isn’t a real world receiver.   Most real world receivers that listeners are using have auto “blend to mono” and DSP as Willie mentions that greatly reduces stereo noise.

Since they started using DSP in modern radios (1990's?) this hasn't been an issue, ESPECIALLY in cars. :) (Which is where MOST stereo listening happens nowadays.)

I haven't heard the noise level effect of stereo vs mono reception on any consumer stereo receiver for a good long time, now. (Unless the stereo is OLD!)

Chances are, MOST at-home listening is on a mono radio, anyway. (Clock radio, table radio, etc.)

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.
