I don't seem to find those models on Icom's website.
I'm also assuming, due to lack of responses, that voted receive is not
popular here in the U.S. Only one other response that indicated Tait offers
the feature, but I didn't go looking to confirm that.

All the motorola xts/xtl series can do it with the correct firmware Tait
and simoco as well.

Voting receivers are in heavy use in public safety, here in SB County
all of the agencies: Fire, both County and City, Sheriff, and City PD
use GE Voters, and we use them on our ham repeaters. There are hundreds
if not more voting systems around California, mostly older GE Types.

Nope, wrong thing. I'm not talking about that kind of voting. I'm talking of a
user radio that has the capability to vote between the repeater input and
output and listen to the strongest signal. A form of talk-around, if you will.

I'm sure chuck was referring to portable radios with voting capability
rather than the repeater end of things.
As for it being popular, voting portables are very popular here. Not much
of a market share I'll grant you. But that's the way it goes I guess.

I'm not aware of many radios commercially available that will do that, but
it would be really nice to have that feature in more radios, or maybe I'm
just not too familiar with the cps of the newer radios. It would be very
useful in wide area coverage systems.

Hi Burt,

Yes you did, Great Sinclair dipole guru! :-)
I got the dipole drawing from your new web site. Thanks! That part

I have a drawing from Sinclair that shows 4 stacked folded dipoles (it does

antenna model) using all 50 ohm cable. So using the 210C4 harness picture

Some people have successfully fought their local phone company, using the
argument that amateur radio is specifically NOT a business (citing Part 97),
and gotten residential or other cheaper rates than the business line rate.
OTOH, some phone companies have refused to accomodate hams, stating
The ones going to the third 'T' should be the same length to avoid
out-of-phase issues.

You're right, Joe. They are both labeled the same, so they are the same
length
but can be any odd 1/4 wavelength.

Thanks. That makes sense and should work out quite well for a
harness external to the mast. Of course the quarter wave of 125 ohm
coax will still be required inside each dipole, but the use of all
50 ohm coax beyond that point simplifies construction.
Apparently Sinclair had different ways of

Yes, I believe this is correct. Whenever I've looked, notice that the

That's correct. The folded dipole impedance is 300 ohms. The 1/4
wavelength of 125 ohm coax transforms that down close to 50 ohms.
This 1/4 wavelength matching section is completely inside the dipole
itself. The transition to 50 ohm cable occurs somewhere near the top

I could send you the firmware for the VX-820 series Vertex Standard portables
as I developed the voting for this radio.
As mentioned, Tait, Motorola, Kenwood, Icom, Simoco, HYT and GME all have this
feature. Some brands may call it
Thanks Gareth.
No, I don't need anything - I'm just curious about the feature since I've never
heard about it, nor had my local Kenwood and Harris dealer.
Could you provide me with some Kenwood model numbers that offer this feature so
that I can pass it along to him?

Follow this link, all 4 of the radios listed under trunking have the capability
