WMPH Signal Upgrade?

[Kris_Henderson]

Was trying to get an idea if WMPH has a chance of getting a power increase.If it were possible i know it would still be directional. Would think this would be the best place to ask with all the great people on this board.<P ID="signature">______________

Too many adjacencies, plus you have to protect WCUR and WKDU.

Process the hell out of the signal so that the needle doesn't move, modulate to the legal limit, and check the level of your pilot. Make sure there's no noise in the system taking up precious headroom.<P ID="signature">______________

Better yet, just switch to mono. Especially for a low-power non-commercial FM station, transmitting in mono really does help to increase the effective coverage area of your signal. And many radios blend all but the strongest FM signals to mono anyway, so listeners won't really notice the lack of stereo. Personally, I'd rather hear pure mono audio instead of audio that keeps blending back and forth between stereo and mono as I drive around.

Switching to mono from Stereo really DOES NOT improve your coverage all that much, either (maybe 2%-5%, if any). It's not worth it. I find also that most mono FM stations sound "flat and lifeless" in their audio. And since most receivers have a "blend" circuit already in place, the switch to mono is a moot point anyway. Visually, if a person is listening to a station on a Stereo radio and sees that the Stereo light is not on, it's usually a turn-off. The only mono station I would listen to myself would be the famous WLNG in Sag Harbor, NY, due to its' unique format and retro sound.

By using some good processor (like an "Optimod", an Inovonics or an "Omnia"), you can compensate for ANY small loss of coverage. Put an Aphex Compellor in front of the main processor and you're in business.

The receiver will switch to mono by itself once it can't get the pilot properly. Not sure if I buy that.

Kris...when am I getting a tour of WMPH? <P ID="signature">______________

Just drop me an email(I provide mine in my profile) I'm usually around any day after 5pm. But can make excepts for guest

On my Sangean DT 200V pocket radio, I had difficulty receiving KYSC 96.9 (Fairbanks, Alaska), which is 10 miles away from me and broadcasts with an ERP of 920 watts.

In stereo mode, the audio would often flutter and hiss as I walked around the house. When I switched the receiver to mono mode, the signal was rock-steady. They play quite a few mono oldies, so the lack of stereo doesn't bother me. -- JasonW

Remember STEREO is an AM DSB subcarrier...thus the hiss and noise....
Mono has up to 23db gain in SN at the fringe when compared to a noisy stereo signal...most radios (auto anyway) will blend to mono but most aftermarkets with a Stereo/Mono button do NOT blend...they stay in the stereo mode unless you make it go mono...Auto car radios, OEMs anyway, dont have that and thus the blend ckt is there to keep the customer happy....
