[BC] Re: [Tech-Assist] STL question

[Mike McCarthy]

I'm seeing two different questions...

I don't see any reason using the AM as a ICR or STL could not be 
done.  There is nothing in Part 73 which limits the means to transport 
program audio in either the final hop or intermediate hop.

HOWEVER, be careful of the translator rules because a sharp attorney might 
see that as a translator without a parent FM station and press that matter. 
Especially if the programming is 100% duplicated day after day.

I would suggest you install a codec of some sort (or P2P IP--Barix boxes) 
and maintain that for proving the program carriage is not a translator and 
that the AM is simply a convenient relay. You could use that means at night 
when the AM may have skywave or lightning problems.  Then make sure you 
shut off the stereo sub-carrier as the programming brought in on the AM (or 
codec) will be mono unless you are using C-QUAM.

That said, in order to avoid all of this and if it's possible, I would 
install a digital STL or something between the AM and FM TX's.
