5100 & 7100 series porgramming question

[gr8tff]

I hope someone has a good answer to this question.

Can a conventional channel be added in the same bank as the P25 trunking talkgroups? For example, can a conventional channel be on dial position 16, while everything else on that bank be P25 talkgroups?

NO. It's just that simple.

The radio can only operate in one mode at a time. Everything in one bank has to be the same type of system. Conventional or trunking, but not both. The best you can manage is to mix analog and digital in conventional mode. That's possible. But you can't scan conventional channels and trunking at the same time.




Yoiu can set up multiple systems to be accessible via the rotary knob, though. Just set up the knob as
a system rotary instead of a talkgroup rotary.

The function you're thinking of was known as "Knob 16" which allowed the radio to jump to the first channel of the first conventional system when the selector knob was on 16. But it was only available on the MPA. All successive radio models don't have it.

You actually can scan 1 conventional channel from an edacs system. The option is called the EDACS Conventional P1 Scan. I have programmed many radios with it. But I have never tried to get it to work with a P25 trunked system. You must set the Conventional P! channel from the options menu and then map a button to ECP!Scan (or a menu option). Once you turn it on, The conventional channle is your P1 channel for your scan list.

I hoped no one would bring that up. Macom's line is that they put it in a while back for a particular customer but they don't support it. It doesn't work very well, either.

Your ECP1S channel must be analog and CSQ. You can program a CG/PL tone in but the receiver will operate in CSQ. It is incompatible with DCG/DPL and digital voice. The reason is Macom wanted to spend as little time off of the control channel as possible so it only looks for carrier then jumps back to the control channel. Further, if you hit the PTT to talk back on the conventional channel your transmit signal will be sent without any signalling. You can program in a tone or DCG but the radio won't send it.

Actually, assuming that we're talking about a portable, you CAN set up the group/channel knob sort of like he wants. In the Portable Radio Keypads tab you set the knob to SYSGRP (rather than SYS or GRP) and then put the system/group options in the positions using the Portable Radio Knob Options tab. That way you can have trunked operation on the first 3 positions, a conventional channel on 4, and so on. You can even mix and match, having EDACS, P25 and so on.

Scanning - no. Apart from the ECP1 scan stuff mentioned above of course.
Hope that helps,
Enid.

This information has definately helped so far. Our county is putting in a Macom system and I have not gotten any good answers about this feature. Does anyone have acces to the programming software manual? I need to have information to fight for this feature. Any help here is greatly appreciated.

That works, but you are limited to only those 16 talkgroups/channels (or 32 if you also use the "2nd bank" option). You lose the ability to use the system up/down and group up/down

That wasn't part of the requirements
