640 WWJZ
- Thread starter JH_Radio
- Start date
It's 50,000 watts daytime, and it is on one of the best possible AM frequencies. 50 kw on 640 is about as good as 1000 kw on 1500!
1000 watts on 550 covers as well as 50 kw on 1500, assuming the comparison is made with the two facilities at the same location with the same electrical antenna height.
There are other variables such as the conductivity of the land in the area. A station on the same frequency in Bismark North Dakota will cover many times the area that a station with the same power and frequency would cover if located in, let's say, Nashville or Atlanta.
It's very powerful East/Southeast but nulled to the Northeast to protect WNNZ Westfield, MA Here's the daytime coverage map. WWJZ-AM Radio Station Coverage Map
Down in Baltimore just yesterday, WWJZ comes in audible in daytime. That transmitter site is huge and the signal behaves more like a longwave signal with how low it is on the MW spectrum. If WWJZ was on, say, 198kHz (like BBC in Europe) that 50kW would likely cover most of the Eastern U.S, especially if it stayed at 50kW at night.
