Now remember the problem is quite intermittent, but seems to be
happening almost daily for short periods.

Monitor the signal levels at the set top box and see if it coincides
with something nearby changing, such as the dock lights or operation
of heavy machinery. Maybe shove a DVM (digital voltmeter) into the AC
power and see if it moves around.

There should be no water in the cable, it's only a couple of months
old and both ends have crimp on connectors and are located in a box
or boat.

I don't like crimp type connectors. Push on connectors are MUCH
better. Also, if the coax came from Radio Shack, all bets are off as
to the quality.


I'm sorry I got that wrong, they are F compression connectors.
Coax was from the cable company.

My drivel:

At my home, knology recently upgraded there system for faster internet.
A cableman said he heard me radiating a block away. he came in and
changed 7 crimp type connectors in my attic a couple of cable runs.
Speedtest.com went from 6 Mbps to over 11 Mbps with just those changes.


It does have diagnostics, I'm not sure if it is each channel though.
But I can get some info out of the box. I'll be there Friday and I'll
get that info and the model of the cable set top box.

Digital set top box diagnostics are different from analog. Instead of
per-channel levels, it might have levels for specific channels.

I'm using Comcast at the boat. We are lucky here (I think) in that
we have a choice of two cable companies.

If it's Comcast, you will probably still have the lower 72 channels
doing analog. Remove the set top box and plug in your TV directly.

Oh, if that is the fact, I may get me some browny points, If I can get
the signal up to snuff, then put the vcr back in the line, my wife could
record her soaps again.
That would get me 15 seconds of hero status!

Just an addition to the termination debate, the marina has about 150
taps, I'd be surprised if 30 of them are connected to a tv and the rest
are unterminated. The line generally goes to the utility pedestal into
a 2 way splitter and then about 1 ft of cable connects it to the 2 taps
for the boat owners.
