Greetings,
I have come across a Wavetek CT-3000B which looks great but has not output, I
opened it up and the 3A card—the Frequency Synthesizer has a loop unlocked, at
least according to the LED on the back of the card. I know that many of the

Is the Canopy system operating in 900 MHz or 2.5 or 5 Gigs? It makes a

I would also look at the termination of the Cat 5 cables as well as
looking at any router which is in the system-we have seen, as numerous

produce a TON of garbage in the 140-172 MHz band at least-I am not sure

Good news John, I trust that the receive antenna is higher than the
transmit antenna? And it appears from what you said that the vertical
separation is sufficient to take care of the de-sense issue-HOWEVER,
that does not mean that your transmitter is clean, only that you have
