[FADCA] Central Florida Backones working again.

[W4RP]

439.25 is the ATV repeater input freq for St Cloud ATV repeater.

It is also used for the Miami repeater but that prob isn't involved with
this discussion.

439 is a common ATV frequencies used for simplex as well -- prob THE most
commonly used freq.

In the past few years,  a  lot of 'throw away'  atv transmitters were - and
still are- sold at 'spy stores'  for video surveillance -- and not really
making buyers aware that they are supposed to be for licensed amateur radio
use only --   they almost all are set to 439 MHz

HI -

Today N3PPC and I re-installed the 9.6kb backbone port at DeLand (to 
Orlando).  The Orlando LAN through DeLand LAN to Daytona Beach LAN 9.6kb 
backbones are all working okay.  The DeLand end of the  Orlando backbone is 
still on a dual band vertical (3dB) 35 ft below the elevation where a 10db 
beam will be mounted.  Signal strength at DeLand is at least 2uv over the 12

mile path to my QTH where the Orlando LAN is temporarily located.  The 
Orlando LAN is on a tri band vertical.  Both ends have 35w output.

When the Orlando switch is moved (35 mile path) both ends will have 10dB 
gain beams and 150 ft agl antenna heights.

Signal strength of the DAB signal at Deland was greater than 3uv - a great 
signal level (35w and 10dB beams on both ends of the 23 mile path.)  There 
is a pulse signal every 10 seconds on or about 439.9000Mhz 150Khz below the 
backbone frequency of 440.0500.  I'm wondering if that correlates to any ATV

standard - as there is a major 70cm ATV system in Daytona Beach.  It is not 
known if the pulse signal is interfering with the backbone.
