[aprssig] 144.39 mhz signal from my SONY 42" HDTV

[Kent Hufford]

Thanks for the responses..
 
Well, it's over 2 years old, so it's out of warranty. It's good to know
others are not having issues. 
 
Maybe something was knocked out of line in the move. 
 
I would doubt the Best Buy/Buy More kinda tech would have any idea what to
look at.

Kent.  I happen to be here at work where we have Five 32" flat screen
monitors.

I tuned to 144.390 on my Yaesu VX-150 and ran it by each.  No signal
interference.  They are different brands and models with the oldest being 6
year old Plasma Sony units and the newest being Winbook and Sceptre.  

If you are still under warranty I'd get a tech out there.  They will try to
pull Part 15 out on you but you hit back with Part 97.  What would they have
to do if this was your neighbors set under warranty and you made an FCC
complaint about it?  Last resort is to actually make that complaint
yourself.

Sweep the set with a service monitor if you have one and note all the other
frequencies it radiates.

Good luck
