Re: [IRCA] WA STATE TIS/HAR INFO

["W. Curt Deegan" <WWWR@xxxxxxxxxxxxx>]

PLEASE read the [IRCA] mailing list guidelines at http://www.ircaonline.org/guidelines.htm

My local TIS/MIS has a pair of transmitters on opposite sides of 
town.  Their synchronization is anything but exemplary.  Being 
somewhat away from them both, I hear them both.  The audio sounds 
like it is under water, with the gurgling sound to it.

I measured the two carriers just now and found them off by 30Hz, just 
as they were months ago when I wrote the city administration and 
pointed this out.  At that time the second system was new and in the 
process of being fine tuned, now it is just neglected.

This city radio station is operated by the department that manages 
and programs the city cable TV channel.  Yet another channel I've 
never watched...don't even know which one it is.  One more hole down 
which the city pi$$e$ away the taxpayers' money.  And they wonder why 
there is a property tax revolt under way state wide.

Need I mention that the "Emergency Advisory Radio Service" radio 
station was off the air for four day following hurricane Wilma, the 
direct hit on Boca a couple years ago.  But what the hey, I was 
without power for eight days, so I shouldn't have even noticed.

God save us from the politicians.
