I've been listening to Vally 98.9 for the last few weeks, it's a great station, There playlist is quite extensive. On Saturday nights Nina Blackwoods 80s show is aired. It comes in well thru out the Merrimack Vally, while driving down 93 south, I loose the station around Stoneham, I wish the signal was stronger.
Do you understand the concept of radio translators?
First lets clarify something, WMVX is not a licensed FM station, they are an AM station, licensed to Salem NH.
Now Costa-Eagle filed and got a FM translator approved for Salem NH, with the calls W255DA. They are not on their AM tower, which is off Brady Ave in Salem NH, but on that big tower you see at Exit 3 off of 93 in NH at Rt 111.
A FM Translator is not meant to exceed the coverage of the station it is re-transmitting ( except at night)
So you have a FM Transmitter with 154 watts of ERP, and based on from what I have heard they cover a pretty big area.
Another eaample of how H.A.A.T. is king.
Translators and LPFM's are designed to squeeeeze into small parts of the spectrum that were previously off limits due to spacing requirements. They can not interfere with a licensed class station .
you have first channel adjacents on 99.1, WPLM Plymouth and WNNH in Henniker NH
on 98.7 you have an FM in Dover NH WBYY
You have a co-channel WCLZ near Portland Me, and another in West Lebanon NH
The FM band in Boston and within 100 miles is the most densely packed in America.
10 years ago the only thing you'd get on these frequencies was pirates like Big City on 106.1, which is now a licensed translator belonging to Beasley.
Beasley's translator can't interfere with the protected contour of WCOD, and there is another translator Port City is using to rebroadcast WNBP up in the Amesbury area ...... W291CC.
but back to your comment, these stations were NEVER intended to be wide coverage area stations.
and LPFM has even stricter limitations, their coverage area is measured in miles and no more than 5 IIRC.
