Al published my EchoLink interface on his web site
(the PSE508 web site) that used the PSE-508. I had a
500 ft cable between the computer and the repeater
using this interface which worked OK until a
high-power AM broadcast station came on line about 5
miles from my location. I had audio from the BC
station on the input of my repeater and also on the
EchoLink audio to the internet. I will have to go to
an RF in-band link to eliminate the problem as I was
not able to get rid of it on the long cable.

Rather than go to all the trouble of setting up the RF link, maybe we
can help you get the broadcast interference out of the cable. After
all, the telecom industry has been getting RF out of long cable runs
for over a century.
The info in this writeup may help...
Mike Sandman has a wholesale telephone equipment distribution company
in the Chicago area.plus he
has a telecom service company... and he has done a number of
interesting things... look at
www.sandman.com...
but his RF elimination page is good. See
<http://www.sandman.com/pdf/Page43.pdf>
Unfortunately his company is up for sale, I hope the web site does
not go away...
