other input?
2. can one add extra inputs to the circuit, I want to use an

Hi Charlie,
The typical rear terminal connections allow a
local mic for base station operation and
probably some type of remote (dc loop current)
control. You'd need a standard DC remote to
use the line terminals.
If you get a standard Motohead (motorola)
desk mic, the color code is as
We are getting some strange receiver noises (intermittent
pops/cracks/static) as well as sudden losses of sensitivity on our 2
meter machine. This is what the top of our tower looks like:

Steve,
I think the Hustler G7 is the cause of your symptoms. It's a light-duty
antenna with many joints to loosen, and the thin conductors are prone to
hairline cracks. My club had a brand-new G7 donated to it for a
repeater, but it was scrapped after less than a year in service for the
I'd like to hear from some of you who have actually deployed a Low Band MASTR II on 6 Meters. The consideration before me is to set up one as a remote base on 52.525, simplex, but before doing so I would like some idea of what to expect in terms of performance.

Keep up the good work. Unfortunately Charmaine and I can't make it.
That's too bad, but it looks like you and Charmaine are going to have
some fun anyway.
The calendar is marked for next years BG festival. Let me know when you
have finalized a date.
Sounds like something I had once before in Fla.
Questions to consider
Is the tower painted?
How often are the tower's jointery checked and bolts loosened and
retightned?
Is the coax grounded every ten feet? And is the coax (hardline( on the
outside of the tower or in the middle?
Is the
The guys are right on the G-7 but what are you feeding it with? What are
your jumpers made with? Coax such as Belden 9913 and Times LMR 400 type
coaxes will do the same thing. Your jumpers should be made from things like
Belden RG-214/u, Andrews 1/25 super flex or Andrews 1/2 super flex are

I have a couple of beer barrel resonators made in England by Aerial
facilities ltd (Now gridcom) :
A brand new barrel is silver plated then painted in grey etch primer/ gloss
The old stainless -steel pickup tube and mounting plate is removed and
replaced by a silver-plated variable length
Thanks to all that sent sensible info about the subjectCheers Dave

First test I would run is a dummy load in place of the antenna with an
isolated tee between the load and the duplexer to eliminate or prove the
antenna/feedline system.
