Re: Anyone here that can do a quick AM study?

I don't see a PM in my inbox. You might want to check to make sure it was sent. Either that or just email it to me...mark@muellerbroadcastdesign.com An existing tower is exempt from the section 106 studies if no changes are made and there is no peripheral construction involved. However, you may need...

Re: Anyone here that can do a quick AM study?

PM the info...I can do it.

Ratchet rule is gone, but that only applies to nighttime.

Re: Negotiating with the tower conglomerates

In general, I strongly recommend that broadcast stations stay far, far, far away from vertical real estate properties. And in typical broadcast industry irony, the broadcast stations are largely responsible for the creation of the vertical real estate properties as they ate their seed corn by selli...

Re: AM Transmitter Shelter

A used prefab concrete communications shelter is the way to go. Most have HVAC built in. You almost certainly won't find one set up for three phase power so keep the expense of swapping out the breaker panel in mind. Those cell buildings are really nice. If you go that route, MEASURE YOUR EQUIPMENT ...

Re: Gates One Blows PA Fuses w/ Modulation

Thanks for the update. There was a similar fuse-blowing issue in another transmitter that turned out to be almost the same thing...bad fuse clips and/or solder joints heating up and literally melting the fuse link.

Glad to hear you found the problem. :mrgreen:

Depending on how far you're moving it you'll need a new front end coil set, too.
Does the FM have that? I know the AM version does.

Re: Changing Frequency Of Belar RFA-1 FM RF Amplifier

The crystal runs at +10.7 MHz of the desired carrier frequency in overtone mode. You'll also have to tune the 'front end' of the RF Preamp board, and will probably have to tweak the output board tuning too. It is a pretty simple circuit that any experienced radio service guy should be able to figure...

Re: AM station to shut down at end of May 2019

With school administrations it is more about internal politics than educational missions, student benefits or even revenue. I suspect someone "up high" simply didn't like it and that was that.

Re: AM station to shut down at end of May 2019

AM stations, unlike FM, are free-range. There is no underlying allocation so once it is gone it is gone. Nobody can come in and 'reactivate' it under current rules. Before Congress got greedy and forced the FCC into the auction window system we have now you could apply for the "former facilities" fo...

No idea how effective with the listeners but their customer that is paying for the RDS ads calls any time the old Audimat RDS encoders lockup or fail.
Typical radio logic: Who cares if it works or drives away listeners as long as we can make some short-term cash! :roll:

Re: RDS options

Sell a few RDS commercials and drop them into a rotation of your station lines or song titles. I can't believe this is a thing. If I saw that on my dashboard I would immediately change the station and delete the preset. Has anyone done any sort of study on how effective this nonsense is? Seems to b...

Re: AM Translators

As long as the translator 60 dbu stays inside the 25 mile circle from the AM transmitter, cutting back from 50 kw to 250 watts would not make any difference --even if the translator's 60 dbu now extends outside the AM station's reduced 2 mv/m. True, but there are many now with 60 dBu contours which...
