Thanks for your suggestion. That is basically what I ended up doing.
I programmed the unit as full duplex remote base, which basically
bypasses the internal controller. I think the only thing I might add
is a timer circuit for hang time. Right now the PTT drops as soon as
the COR drops out.
I have seen the license for the UHF pair that they have but the hotel is
not interested in purchasing new equipment for the current system of VHF
radios was just bought last year. I got stuck with this project of
getting a repeater pair and programming the radios. If I would have

Mike,
Does this problem occur on one channel or all???
If only on one then the TV's LO might be the problem. TV IFs are 41-47 MHz
with the video carrier at 42.25 MHz. I think the LO would be 45.75 MHz above
the channel freq. Ch 3 is 61.25 MHz. Since so much these days uses some type

I'd like to hear from anyone who uses an IC-706 as a remote base on a
repeater regarding keying the 706 via one of the 706 rear panel
connectors..how did you do it? The one we have isn't working as
easily as it appears it should...
Thank you,

Bob,
I could use a duplexer and a Micor if they are capable of being tuned
to the ham 440 band. Do any of the radios or duplexers have a frequency
written on them? Also, are these items made for rack mount or for table
mount?

I'm sorry, I forgot to put in that this is a vhf repeater.

Maybe it is not too late to turn down the contract. Did you really think you

You can't control what the FCC allows.
You could just make a go of it with a simplex system.
Bob,
I've seen on spectrum anal spur problems with radio shops turning up the power
on GE Mastr IIs and get lots of unwanted spurs out of the PAs. This was done
of course as to impress the customer with a watt meter.
It also may not happen on the bench for a short time, but with use it can
I spoke to a tech at a local radio shop, and he seemed to think that
there might be a transistor shorted. He mentioned a large transistor
that attaches to the frame of the radio, and I do recall seeing some
modification around there. I know just enough to be a little
dangerous, so I guess
Folks,
I've been doing TONS of reading. Mostly I'm hearing that fiberglass
radome antennas aren't so good in repeater service. I'm looking for a
dual-band antenna (2m/70cm) for a 70cm repeater and 2m remote base.
I'm not finding much that isn't a fiberglass radome. I'm not set on a

I have a Diamond X50 high atop the School gym roof at about 1588 ft
asl. It runs into a MFJ diplexer and serves a 20 watt 440 repeater and
65 watt 2 meter tranceiver just fine.

The problems most people have with colinears in radomes is (1) leakage of water
into antennas assembled from more than one section, (2) internal connections
which break or develop intermittents, and (3) they're often completely
destroyed in a lightning strike, sometimes spectacularly,

Cort,
(1) Can be addressed by using antennas with one-piece radomes. In
theory, the right preparation to seal junctions might also work. In
long-term installations, the gel-coat on the radomes will break down

I hate to be a nag, but it would also be helpful if you provided some
combination and/or module part numbers. I am not being sarcastic, just
realistic. If you can identify exactly by part or model number what you
have, it makes it much easier for the Elmers on this list to zero in on the
problem
A friend and I used direct-burial heat shrink tubing with some kind of
sealing goo in it on a multi-piece antenna and did a PVC holder for
the top end. We were pretty happy with it, but I've heard so much

Back in the 90's a Diamond 23A 2M antenna was at 5000' for 10 years
before it was replaced. It stood off the SE corner of a 300 meter national
transmitter tower at about the 30M section, and serviced a vast area of
country.

Looks good on watt meter, but not on spectrum anal.
What kind of spectrum do you receive anally?

Due to a purchasing mixup our ham radio club has this antenna for sale
new in the box. It was ordered for the 2m ham band at 144-148, our

We are located in South Florida and I might be talked into meeting

The simplex system is not working hence the reason they need a repeater. I got
the fcc form filled out to get a vhf pair in the area for them so we will see.
The system was abandoned by the former shop as they went out of business so its
just me now for the system to get them up and running.
Checking with the license two of the stations are 200 some miles away at
another little America, so we have one frequency on site so we need a
new pair to be able to be complaint.

Sorry if this is a little off topic.
I have located what appears to be a Motorola R2001 service monitor,
although there is no model number sticker on it.
I identified it by the pics on the net.
Does anyone know what the difference between the A-B-C and D versions
