Im a Cox installer. I went to a trouble call where the cust
told me that the Philipino channel would go out some days around 5:30PM. 3 TV's,
1 HSI Modem, only 1 TV had the box and the problem. 3 way in attic with the 3.5
leg to the modem, 7 leg to box, and other 7 leg feeding a 2-way feeding the 2
other basic TV's.
Did a Home cert on the way there...box and modem were
passing. Decent levels to back of box. A couple more DB's might make me feel
better though. This is the second box they had been through, so I ruled that
out. A tech had been there before me and reworked the 3-way in the attic and
replaced the barrels in the wall plates.
After listening to the cust explain the problem, I really thought it had to either be headend related, a sat issue, or something is going on around 5:30...maybe a faulty microwave or a
neighbor is amping a signal around the frequency of that channel.
The previous tech did not remove the NIU even though the customer did not have
phone. I went ahead and did everything Im supposed to do. Went up the pole,
changed the fitting, checked levels (good), turned power off to the NIU, checked
ingress back (passed), and tagged the line.
Went to demark, removed NIU, added GB with new fittings and ground. At the wallplate, I gained allmost 2db on 133. I was there at 5:30PM and it didnt happen. I called the customer from my
house that evening to see if it had happened again. No, and everything looked
great.
I had the cust keep my number to call me if they found anything
out or if things changed. Im hoping they do call with something like...oh yea,
my neighbor has a 88 gigawatt Ham Radio. Anyone ever seen this before?
