KYET

Rick S. Newman

Rick S. Newman

Has KYET 1170 AM Golden Valley surrendered their license and given up the ghost? They've either been silent for the past few days, powered down to their 1w PSSA or changed their pattern. I live in Boulder City, have an AM stereo receiver and had been enjoying the music I used to play 40 years ago as KRAM jock. Any information would be greatly appreciated.
Thanks.

Rick

"KYET 1170AM is currently off line due to high heat. We are working to fix the issue."

I guess cooling that 6kw source during the afternoon means a little more than a few computer chassis fans are needed in the transmitter shack...

I just spoke to the KYET engineer.

When it gets into the lower 100's outside there, its 125+ inside and the AC they have cant keep up and a digital to analog converter overheats and the DX10 transmitters stops modulating.
 
Acknowledging summer heat in AZ. would be akin to acknowledging Catholicism in Vatican City. Could be worse I suppose....there's always Needles, Blythe, Yuma etc. And yes, it'll take more than a couple of Wal-mart floor fans to cool down that final in a 6K AM transmitter. Glad to hear KYET will be returning. Good luck with it and sincere thanks for your response.

They do have more then just fans in there.

Unless you have some big central air unit, which is often hugely expensive..... AC's just cant keep up.. and even a central air unit.... when it gets to a certain point, no matter what AC youve got, its just gonna be a bit hot.. and broadcast gear can only handle so much
 
With regard to the floor fans I was being a bit facetious. I know how hot the 3-500z final in my 1KW amateur radio amplifier can get on only SSB peaks. A 6K AM (constant duty cycle) BCB transmitter in an enclosed structure in the heat of an Arizona summer is I'm certain a formidable challenge to even the best and most efficient cooling system. Imagine if it were an old 50kw Continental 317C or something similar. As I said it could be worse.

Fair enough, but are they legally off-air, due to the technical issue in the eyes of the FCC?

You have 10 days before you even have to notify the fcc and 30 before you ask for permission. Plus, in cases like this, the FCC is pretty forgiving even so.

And yes, this would qualify as quite a valid reason to be off the air
 
If it really is the D/A Converter, a thermoelectric cooler should be able to keep that cool. Except that there is probably a PC in the transmitter shack as well.

Thats one of the issues the engineer headed out to the site today told me was the reason for 1170 being off air

There are all kinds of acceptable reasons to be off the air.

Examples include things like:
-Old transmitter, spare parts hard to find.
-Lightening damage to transmitter or ATU
-Tower down in winter and can't repair due to bad weather
-Contract engineer retired, can't find new engineer.
-Lease expired and we can't get on property
-Vandals broke in and stole things; trying to get a loan to replace.
-Lawn mower hit guy wire and tower fell.
-Telco stopped leased line service, trying to find best STL system.
-Manager died in car accident. Nobody to run station.
-Ran out of money; trying to find financing or a buyer.
-Owner died, kids don't want to run station. Off pending sale.
-Tower site inaccessible due to landslide on access road and county can't fix till springtime.
-Station had a two person staff plus owner. Both staff members quit, and can't find replacements.

There are many others. The FCC is very understanding in accepting reasons.

In some cases, stations have been off for several years. I know of one where the site flooded, and the flood plain was declared unsuitable for any structure by zoning board. To get a new site plus all the environmental and city permits it took several years. As long as the FCC saw progress, they knew the effort was in earnest and granted special authority.
