That was way before the club bought the new (then) Motorola Micor
repeater.

The Palasades Club's new Micor repater on Hollwood Hills, the one I
helped to build. I still remember that project, the late Walt
Bronstien was just learning to spell R A D I O !!
Does anyone know of a manufacturer who makes a VHF-UHF handie-talkie
for commercial use?
Thanks!

The AT-600 was programable in the 2m/440 range as well as commercial and gmrs
bands.
It could be opened up well beyond that...of course then type acceptance
probably goes outthe window.
The HTX-204 was based on the AT-600 but only has a subset of the menu
functionality that the AT-600 has.

These type of duplexers are also, only good for about 5MHz split,
and will not work in the ham 2M band with a 600Khz split.

Hi All,
I recently acquired a Tait T-300 VHF repeater unit. Looking at using it in
one of our repeater installations.
Got everything working, and appeared to be putting out all the correct
levels, power etc.
However, after a few days, I was advised that the audio seemed to be low on

I would suggest the Decibel Products DB-408 or the
DB-420 antenna.. I have two DB-420's and 11 DB-408 in
service in the 440 band and they all work great.. They
are all the 450-470 mhz model.. Put them up once and
walk away..

Hi Kevin,
I use a Tait 300 series on my 6m
repeater.
I have found that although the filter is
technically correct for the 12.5KHz spec ( i.e 2.5KHz deviation max ) that few
if any Amateur rigs are setup for this correctly out of the box.
I have changed the filters in all of mine for
Hi there;
You have got a T300 Narrowband
repeater (12.5 KHz Channel spacing). The IF Filter that you have is for 7.5 KHz
bandwidth rather than 15 KHz (Which is for 25 KHz Channel spacing).
Unfortunately you have the last
of the T355 receiver's and these were double conversion with 21.4
I agree but lean toward the 408 over the 420.

What does the list think of the 411 vs. the 413? I'm using the 408 now but I'm looking to cover into a one particular direction over the other.

I think my wife stole my Decibel catalog ;-)
The 413 is 8 elements and the 411 is 4, right?
If you're going to side mount on a tower, use either. If you're going to top
mount, I prefer the shorter 411. The longer antennas have too much flex in
the wind to top mount, in my opinion. Others will
Right on the money... the 420 end mounted at the top
of a tower has enough end torque to actually flex a
Rohn 55 section (in a 35mph) quite a bit. Enough
to make me really nervous.
You can in-line the dipoles of a DB-408 per
Decibels information to obtain a sort of colinear
pattern,
Besides, that's a lot of extra aluminum to get 3 dB extra that 95% of the
users will never notice.
I know, I know, some of you won't agree, that's fine. But that's my story,
and I'm sticking to it ;-)

Chuck is correct. The 413 is 18 ft 4 inches long and is rated 12 dB gain
and rated to survive 1/2 inch ice at 90 mph.
The 411 is 9 ft 5 inches long , 9 dB gain 112 mph wind with 1/2 inch radial
ice.
The 408 is 6.6 dB gain and will survive with 1/2 ice at 85 mph.
The 420 is 9.2 dB gain 18 ft 1
I think the concern is that of many
trickle charge systems. They are designed to float the batteries and switch
over if needed. They are NOT designed to recharge a depleted battery bank.
All this is fine unless you lose power on the site for 48 hours and run your
batteries flat and then

Speaking of leaning . . . most of the tower top DB420's down here in
