[WXBH-Discuss] Still Here...

Thu May 25 23:03:26 EDT 2006

Hmmm. I sent an email out earlier this evening, but it hasn't come through 
yet? But I will revisit it tomorrow. I am interested in meeting Sat. at 
3:30pm at my house or at the Brick House after I get off of work.

Also, I'll work with John Hicks on seeing if we can put together a tech 
committee listserv. We'll discuss that more soon. I am out the door to work. 
Will be in touch with Tech/ Engineering Folks tomorrow (depending on whether 
previous email goes through).
Good night, Aron

>>   Hello! With Derby and other ongoing projects, I've been swamped and

>>
>>   1) I suggest you hold up on the studio-transmitter link discussion 
>>until the
>>   antenna relocation site is decided. Has anyone followed up on my 
>>suggestion
>>   of the old LG&E radio relay tower at 7th & Ormsby? The new site 
>>location
>>   will definitely bring in or rule out certain STL schemes. I can add RF
>>   equipment (antenna, feedline, transmitter and, if needed, microwave 
>>STL) to
>>   the equipment listing anytime.
>>
>>   2)  Be  VERY sure that any wire and cable you run through the walls or
>>   roof has jacketing that is
>>
>>   properly fire-resistant (e.g. "plenum rated") and wire of the proper 
>>gauge
>>   (diameter).  This  goes  for alarm, security, audio, video...anything.
>>   Inspectors WILL check!
