I installed a remote receiver for a repeater this last summer at a site where a
900 mHz wireless distribution system, along with a 5.x gHz backbone was
located. The site also had a 2.4 gHz local wireless router installed.
In order to operate the remote receiver the squelch had to be as tight

Why have the the WIFI at 120 feet on the tower for just use by your family.
Drop the WIFI to 50 feet and it would probably be fine for around the house
and yard on the WIFI and the repeater problem would go away most likely.

You can expect to spend at least $1000 for a used MTR and anywhere from $4000
to $7000 for a new one. 40 watt units are a little cheaper than 100 watt but
not by much. I'd recommend looking for something else because the MTR's can be
expensive to repair should any repair be needed that requires

I'd highly recommend a Motorola MSF-5000 that's PC programmable. They are
bulletproof and can be had for probably half of a used MTR-2000.

However, I'm seeing more and more ham clubs without the personnel to service

The tried at 110' was not enough signal, -80 dbm was best, at 120' we
hit -72 dbm so that is where it had to go. What I am looking for is
possibly a filter that will solve the problem and allow them both to

Set the Ethernet link to 10 mHz and the problem should go away. The
Canopy gear doesn't go that fast on the RF side anyway. If you can't do
it on your end the ISP can easily do it on theirs. The other post about

Sure, it'll help. Anything you do to make your receiver less

Let me know if this helps.
