WMEX's response on facebook group to "where's Joe":" We apologize for any inconvenience and thank you for your support."
Really? I sat in on a couple of Air America (Network) sales pitches, and they had ZERO to do with demos, quarter-hours, or any other metric that was used to sell radio at the time. They were selling it as a tax-deductible political contribution disguised as advertising.
50 kw on 1510 is covers about the same a 1 kw on 540. You need every watt you can get on the high frequencies in order to overcome man made RF noise and to penetrate buildings and homes right there in the local market. In a metro like Boston, any AM (other than unique ethnic offerings) get's very little listening outside its 10 mV/m contour.
WMEX's daytime 10 mV/m barely reaches Milton and Dedham to the south and Wilmington and Lynnfield to the North and just a tad beyond Wellesley to the West. That same contour covers just 1.8 million out of 4.7 million in the total radio MSA.
And, yes, high-dial stations generate good night skywave. That is irrelevant; you need lots of power today to be listenable in noisy metro areas. WMEX covers well only about 1/3 of the MSA, and at night it is much worse.
Lots of power sent everywhere but where you need it is a waste of money. The cost of power will increase, and AM listeners and advertisers will decrease.
The AM dial is full of higher powered stations that push as much power as possible over as much of a market as permitted and then out to sea.
In the last five decades, AM stations that have increased power have done so to better cover their local market and to combat increasing noise levels. Nobody builds a 50 kw facility to be heard at night in some distant city, state or country. They build it to penetrate buildings and to overcome noise.
Part of the problem is that 50 kw is not really high power by world standards. And at 1510, 50 kw is barely a full local signal in a large metro area even if run non-directional.
The guy that owns WMEX is very sharp technically. The power bills of AM stations in general will be what kills them.
The power bill is a small part of the operating expense of a radio station.
Let's take WBZ. A 50 kw solid state transmitter (without tower lighting, AC, etc) will use around 100 kw of power, which at an average commercial rate of around $0.15 per kw/h will give you $15 an hour for power, or around $10 k a month in total expense.
When you consider that WBZ billed $25,000,000 last year, $120,000 is petty cash. Reducing the power of such a station will not help much overall.
And if you want to play on the same field, you need the power for coverage and building penetration.
I am not speaking of the price of a current KWH, I am speaking of the increase when coal plants are pulled off-line. Want to buy WBZ? It is for sale. When you aren't being propped up by a radio group every penny counts.
WBZ is the 26th highest billing radio station out of 11,300 "full" (not translators) commercial stations in the US.
Even if energy costs double, that's a barely perceptible change overall against such high billing.
In fact, I used the national average for non-commercial services (residential) for the cost of energy and not the Boston area commercial rate which is about $0.13 per kw/h. So actually the monthly cost for a 50 kw station is going to be more in the $8,000 range assuming a solid state transmitter and 24/7 operation.
The annual WBZ transmitter electric bill is much less than a good salesperson makes in commissions. Put these things in perspective, please.
I am putting things in perspective. Every dollar counts with a stand alone 50KW AM getting off the ground. The transmitter isn't one of the newer models and sucks the watts.
If we were talking about a 1 kw station at 550 on the dial, would you recommend that they cut to 250 watts?
A 50 kw station at 1510 will cover almost exactly the same area as 1 kw on 550 (assuming same conductivity, same antenna efficiency, etc.).
So 1510 needs every watt of RF they can legally produce as they are at the wrong end of the dial.
Even an older high level plate modulated transmitter is not that more expensive. If the station plans to be competitive in programming and play for ratings, it's just a cost of doing business like rent, staff, insurance, phones, ratings, etc. If they don't plan on competing and, instead, sell with a brokered model or go for an ethnic niche, they still need the power to penetrate homes and buildings where most listening takes place.
Really comparing a 50KW station to a 1 KW station's power bill? If the towers for a low freq station didn't have to be to the moon it would be a better buy.
I was making the comparison to show that you need every watt in a large city at a high dial position because coverage on those channels is so much less that at the lower dial positions.
My point is that if you had 1 kw at 550, you would never consider dropping to 250 watts. So why, at 1510 would you consider dropping to 5 kw or 10 kw?
Oh, and the major issues with towers at any frequency is getting land and zoning approvals, not height at most locations. Yes, you can use a 200' or shorter tower on higher dial positions but you can meet minimum efficiency for most classes of stations at lower frequencies with reasonably sized towers. I owned an AM at 570 and we used a skirted top loaded 240' tower very successfully.
