Anyone here that can do a quick AM study?

Post by kkiddkkidd » Fri Jun 14, 2019 7:32 am

Hi all,

My 2nd or 3rd oldest client (and good friend) is being evicted from their long time rented TX site for nothing other than vindictiveness of the deceased former owner's daughter.

Can anyone take a quick look at the station as it exists today and give us some idea of where it can potentially move to. They have suddenly had a couple offers of donated property but none of it is very close to the existing site.

Was the ratchet rule ever rescinded?

Regards,

PM the info...I can do it.

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

Thanks Deep. PM sent.

On the same subject,

Is an existing but unregistered non-broadcast tower (ie, 2-way tower) exempt from the environmental and cultural impact studies if a broadcast station is added to the tower?

Is the VALCOM antenna bound by those same study requirements?

This station is in Maury Co TN which was know as the Phosphate Capital of the World for many, many years. A large portion of the county has been strip mined and then refilled to depths up to about 100ft below natural grade. Finding a site that has already been impacted / disturbed / destroyed won't be hard in this area.

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 to register the tower in order for the application to be processed if it should have been registered (fails TOWAIR, etc.) and wasn't, which can set off an avalanche of other things such as those section 106 and environmental studies if they should have been done earlier but weren't. It doesn't matter to the regulators whether the site is "pre-disturbed" or not.

A Valcom antenna has the same "triggers"; if it needs to be registered due to the height and proximity to an airport then you'll have to go through the rest of it too. I wouldn't recommend one of those except as a last resort. They are expensive and have their own issues, not the least of which is the FCC won't let you use them below 1200 KHz even though the minimum efficiency rules have been changed. It might be better to contact Tom King about a "Kinstar" arrangement which is basically a bunch of wood power poles and wire.
