Technical question regarding South Mountain tower sites

I just noticed that KDKB has permission to move its antenna from the tower it shares with KMXP to the KASW (TV) tower. I know that the engineering geniuses behind these stations read this forum, so I was just wondering why they couldn't just move to the KSLX tower that Sandusky owns outright instead of leasing space from someone else? Not enough room for the new transmitter in the KSLX shack? It sounds like they could save money over the long run by having two co-owned stations share a tower and antenna as in the case of KTAR-FM and KPKX. There's got to be something that is preventing them from doing this.
 
The KSLX tower was checked for having more than one FM on it and it cannot take on the weight of another antenna system. Ther tower would have to be replaced and the building is too small to handle another FM
 
Gumpdusky could save even more $$ by moving the xmtr to the canal Tower of Pow-Pow-Power in South Scottsdale. Of course KDKB's coverage would be significantly reduced, but the Goldminers will keep station on the air for at least all day. Nights are dependent on the lamptimer.

Actually KSLX a long time ago was on the 1440 tower before it was moved to South Mountain

According to the 1968 Vane Jones station guide, KDOT-FM (which was shown as a CP in that edition), was 50,000 watts at 230 feet HAAT. Per the 1970 book, the HAAT was 170 feet. Did they originally misunderstimate the AM 1440 tower height?

Since you seem to have an intimate knowledge of the inner workings at Gumpdusky,
how about telling us once and for all what the PSRA wattage is on Lumberyard 1440?

You've mentioned a number of times that the Harris Five can't get down to 52 watts,
so what is being run from 6 AM to monthly sunrise, LST*?

And what's the deal every other April, when KAZG stays on at night? Why, and with
how many watts?

*: LST = Lamptimer Standard Time

We have asked these questions many times from "Catfish" with a "c" and have yet to receive an answer. My thinking is that "Catfish" is an engineer or a former engineer for Sandusky and doesn't want to say anything that could get them into trouble. It's totally understandable why he would remain silent on this subject and I commend it. But, for us Lumberyard fans, we would love to have answers to your very relevant and perplexing questions, Oldiesfan.

I also wonder what the recent activity on the KAZG FCC license is all about. Since this activity doesn't have any negative implications for Sandusky, perhaps "Catfish" could help clarify this. That piece of the puzzle can be found here: http://licensing.fcc.gov/cgi-bin/ws.exe/prod/cdbs/pubacc/prod/app_list.pl?Facility_id=11272

Thanks in advance for any insight, "Catfish"! :)

If it's anything more than 500 watts, Gumpdusky aint legal. But of course that hasn't stopped KFuNN from running 22kw post sunset when they're supposed to be at 100 watts. Aint Ancient Modulation interesting?!
 
I am not the engineer for 1440.. the 500 watts is a pre sunrise authorization which is used for almost every month of the year. At sunset they go off the air, no 50 watts, no 500 watts.. static.

It really is 500? So the complicated formula in the PSRA (where you divide by X and
then multiply by the square root of 23.7) is meaningless?

And no legal ID either! ;D

No need in doing the math as Lumberyard 14~Forty's PSRA lists the months and power settings. For March, April, September, October and November, the Goldminers shovel out 500 watts. They shave 10 watts off that in December, January and February. How the men who mine the gold back down the Harris V by two percent is a mystery to the Nurse and me. Now post-sunset is a lot more complicated, and we don't blame Gumpdusky for not bothering. But if they could lease a couple more cell antennas on the South Scottsdale Tower of Pow-Pow-Power, then the Goldmine could afford a transmitter capable or running with 52 watts at night!
 
Be nice everyone...maybe they'll simulcast KAZG (24 hours a day) on 93.3 HD2 once their new Christmas gift is up and running!
 
actually KDUS will be on the HD2 of KDKB after the first of the year doing the full new FCC IBOC power level. Again the Gates will not pass the FCC NRSC2 compliance at 52 watts so lets not beat this up anymore.. maybe the owners will soon approve a new transmitter that will allow the lamptimer to stay on 24x7 but with not much of a ground system why bother.. however listen to the 49 watts of KXEG 1280 one hour after sunset. It get's out to the 60/10 split at night going east and has an unnbelievable signal going north west. That station has 5 different power levels during the day and has a complete ground system.

With 52 watts and a high end dial position, Nurse Jeff and I wonder how much better that night signal would be with a real ground system. However when you look at the projected night coverage, it's easy to see much better real estate than what 12~Eighty covers from their west side location. Tempe, West Mesa, South and Central Scottsdale plus East Phoenix aint too shabby. But if Gumpdusky sticks to worn out oldies, no point in going fulltime. Whereas a brokered format does make sense 24/7 for Lumberyard 14~Forty.

Now if only catfish would splain' those few times the Gold Mine stayed on overnight. It's almost as mysterious as to what really goes into those McRib sandwiches :eek:

According to the FCC site, it's just two levels--daytime (2.5 kw) and nighttime (49 watts):

Yo catfish (with a "c"), since you seem to have the ear of the Gumpduskers, could you ask
why they've failed to do a legal ID at sign-on and sign-off most days for at least five years?
And BTW, the lamptimer has now drifted to over four minutes late.

You have to look into the correspondence folder for the PSRA and PSSA authorizations. catfish got it right. Same applies for all Ancient Modulation stations that used to be daytimers... including our beloved Lumberyard 14~Forty!

Yo Oldiesfan...shouldn't all of this be over at the infamous Day In The Life of a Lamptimer post? Afterall this thread got started with Gumpdusky moving KDKB to a new site on South Mtn.

Isn't KDUS on 97.9 HD2 already?

I know that KUPD's HD signal is not reliable, and it seems to be off every other week, so that might be the reason. A new antenna for KUPD must be in next year's budget.
 
catfish said:
Good call dr a... have you heard anything on KDKB?

Nope. In spite of our fascination with one of their Ancient Modulation stations, Gumpdusky runs a solid group of 3 1/2 stations. Both KDKB and KSLX do well in PPM and at the bottom line.
