WEMG AND WTTM

[Joseph]

If You check these 2 stations, 1 WTTM is 10 kwatts at day and 1,000 watts at night.

WEMG is 1,000 kwatts at day and 250 watts at nigh. but both transmitter site are so close less than 4 miles of distance and maps shows almost the same coverage when the difference between 10 Kwatts and 1 kwatt is big.
can some one give me an explanation?

The lower the dial position the less power it takes to put out a similar signal of a higher dial position station.....This is why the lower dial positions are often regional stations (5,000 watts or lower).....BTW, WTTM is an X-band station, and all those stations were originally licenced to be 10,000 day/1,000 watt night, omni directional/stereo stations. I understand some stations or at least one x-band station is now DA with lower power, but generally to serve a COL, a 10k signal would be needed even though that section of the dial is reletively quiet.....Carl<P ID="signature">______________

Thanks,
Your explanation is very appreciated and I undertood what you said,But between 540 and 1680 there is a very long distance diference in the Dial.
But Between WEMG 1310 and WTTM 1680 is not too big.

well actually 1660 WWRU an expanded band station is Running 10kw Day and night
with a directional pattern.
Not sure If WEMG is on a standard Series base fed tower or not.
WTTM is now On a huge Unipole. I also belive the ground system may haveto do with it.. WEMG is near the water or swamps.. WTTM is more inland. however the ground stays pretty well wet after a rain...
I cannot comment on WEMG but I can On WTTM..
I didnt like the "BEN format" in Philly... I didnt like the "Jack format" in NY....
We came up with the Newest format Out there the "Ted format"
people seem to Like it..... its a really good mix of stuff From old to New.

Actually, WEMG runs 579 watts day, 250 watts night. It's classified as a 1,000 watt station, but there's a special note on the license. The lower power is to protect Asbury Park without being directional. The tower is 201' tall, and is series fed. The transmitter is not in a swamp, but is on the edge of the Delaware River, so the ground conductivity is excellent. The transmitter is a BE AM1A (the last one they built), with the Continental that was in use before 1999 in place as a standby, although it's never been used since the BE went in.
