Ahh. Thanks guys. I was afraid that would be the case. You see I have lots of Maxtrac/Radius low band radios and fourteen VX-5500. I can't seem to find anything that works between both of them. The boards to allow the VX to do MDC is about $80 because they need not only the MDC board but also an ...

Hi guys,

As I'm sure you all know MDC1200 PTT ID will display the ID it's receiving from another radio as long as the "Call List" has the necessary entries to display a proper ID.

I have acquired some other brand radios that don't offer the MDC1200 PTT ID system but both radios will do DTMF PTT ID ...

Yeah the HT100 is still used by every department that hasn't gone digital yet on our area. It's a great radio that's for sure...it has signaling (every type known) and DTMF pad options...but it's huge compared to the GP300 or HT750...but I might have to let that go because of the price. They are ...

I want to thank you guys for the input. I learn a few things from that last few post. This information is very very helpful.
I should stress that these portables are being used as extender portables on VHF itinerant frequencies. They are connected to a lowband mobile radio that is on a repeater. So ...

Hi guys,
I need some opinions on some portables. We have been using the GP300s since 2000 and with this new system that we are building I would like to do a narrow band conversion to our existing GP300s..if it's cost effective and when purchasing new radios buy something that is narrow band ...

Ahh yeah I did remember that most public safety systems are full duplex. Actually most dispatch public safety systems if I remember correctly are either remote base's or the base station itself IS the repeater. So of course if you key the transmitter of the base the transmitter IS the repeater ...

Yep. Commercial products worked out those contention problems. They did it with busy channel detectors and random timers so that one unit, usually the first on scene, would be the master, and all others would remain quiet.

Ah yeah like the Pyrimid unit...huge money and waaaay more than we need ...

Hi Bob,
Hey thanks for the input. I'm using pin13 for the extender itself...although it could also be used for more than one function if properly isolated.
If I did use pin 13 for switching the extender transiever it would mean that the extender would be on when the mobile was powered up. This ...

Ok Bill...that's what I thought but before I designed an external way of switching the extender on and off I wanted to see if I could do it with the front panel controls.
Thanks for the reply.
Chris

Sorry guys. Just noticed some type errors and can't find a way to edit the post.
The title was suppose to read "latched output with accessory port on Maxtrac/Radius"

Hi guys,
First post here. Thanks to the admins to fixing the "register" link to sign up.

My first question is a question about the Motorola Radius and Maxtracs with a 16 pin logic board. I made a bunch of mobile extenders out of P110. These units have a 16 pin accessory plug on a 24" cable that ...
