No sat 91 on Expressvu

[Trickyrick]

Hi guys Bell is no help with this
Have a dual tuner receiver when I run the switch test I have no sat 91
on either tuner (1 or 2). When I check the transponders on 91 I only
have a signal on the odd ones. I’m using a SW44 and I have another
receiver (5100) when I do the switch test its ok both sats come in
fine it’s on the first port of the sw44. It’s not the receiver I
moved another dual tuner receiver to this location and it does the
same thing but works fine at its original location
What would cause this. Only thing I can think of is the switch but
one port on it is ok can the other 3 ports be defective not letting
signal of even transponders through

If you have access to the switch it should be a quick and easy test to
swap the cables, but I bet you'll find that the switch is fine and the
problem most likely lies with a coax connector or a section of coax
itself. If I recall correctly, the odd TP's use a lower voltage (about
13 volts?) while the even TP's use a higher voltage (about 18 volts?),
so the problem seems to be a voltage drop on the cabling between the
switch and the 'bad' receiver.
