Which of the jedi radio series can support RSSI Voting in a scan group?

IIRC you need the FLASHport option called Q387 Conventional Voting Scan. The MTS2000 and MCS2000 can do it, not sure about others.

Have a smartzone type two trunking enhanced , I do not seem to find where I can set the voting-any ideas?

Not to change the subject, but can someone explain what this feature is to begin with. It sounds pretty cool but I've never heard of it.

Ok
Voting is for a "multi repeater sytem "that is usually all linked.
One can set a number of channels and when signal is detected on any of the assigned frequencies -it does a very fast RE-SCAN of that group and choses the frequency that has the highest RSSI (Radio Receive Signal Indication).
This allows the radio to analyse the signals of all the repeaters in a group and places you on the strongest signal channel.
There are many ways one can enhance the facility to suite ones needs.
Most modern systems such as GSM , Mpt1327 ÄCT NOW Voting Message "all use the basic principle.
Think of it as a Repeater voting system done by your radio that you carry.

I got to play with an Astro Spectra with the "Vote Scan" option a while back.
The feature is really intended for use on a voted system that consists of multiple repeaters spread throughout a desired coverage area. Each repeater would have a different output freq (so their coverage can overlap), and all must share a common input frequency so that a mobile's signal is "voted" from the site that hears it best. The voted signal is then simultaneously transmitted out all repeaters.
The Astro Spectra "vote scan" feature basically automates the task of the mobile user selecting the strongest repeater output.
A "vote scan" system just looks like one channel to a user of an Astro Spectra--that is, the user has no idea which site they are receiving. The radio just scans the repeater outputs, and automatically locks on the strongest one.
I have no experience with the "vote scan" function in Jedi or MCS radios, though.

Is it a FLASHport radio? If so, what's the flashcode?bradlington wrote:Have a smartzone type two trunking enhanced , I do not seem to find where I can set the voting-any ideas?

You know, up until now, I always said "Gee, it would be nice to be able to have a portable vote but it would be a little cumbersome to have a big GE voter on my belt."
I guess they are ahead of me.

It's been in common use in Australia, New Zealand, South Africa, Europe etc for well over 20 years

Not sure if this is voting, but it sounds like it...when we go north, we have to call UP dispatcher 68 in Omaha, NE by dialing *68 on the locomotive Spectra keypad on channel 1414. The DS will almost always come in crystal clear, but if not, we can ask him/her to try a different tower, and it will help a lot. Is UP's microwave system set up for voting?

That sounds more like manual transmitter steering to me than voting.
FWIW, Voting Scan has nothing to do with a voting system per-se repeater-wise.
With regards to the UP system, most likely they have a console there where the dispatcher can select from one of a number of transmitters at the press of a button.
Nothing to do with voting (or microwave necessarily, though it's possible.)

On a system that uses voting scan, there will be a bunch of repeaters around the place transmitting the same thing at the same time on different frequencies (a voting scan list is usually called a votegroup). Your mobile radio will automatically scan through these predefined channels, and select the one with the strongest RSSI, while appearing to always be on one "channel".
