From what I'm reading, it seems to be intended for analog simplex channels where units may unintentionally attempt to transmit at the same time, like a fire ground tactical channel. Supposed to enhance the chances that the radio will unmute and hear at least one of the radios instead of remaining mu...

Thanks for the suggestion on looking at the firmware release notes! I noted several abstracts on "Garbled audio" and one mentioned the "Concurrent Rx Enable" feature. After closely observing the behavior of my 8000 using the Multi-System scan list, CQPSK P25 audio was garbling, e...

Thanks for the tip on the firmware! Hadn't seen that one, I'll take a look.

Jim

Yep, that was my thought as well. But it is set correctly to CQPSK. Very weird.

Hi gang, I just put an APX8000XE portable in service and I am noticing that my APX7000 U/800 seems to do a lot better on receiving a distant 800 MHz P25 simulcast system. The 7000 is solid decode, but the 8000 has noticeable periods of garbling and robotic voices. Just had an alignment done on the 8...

It will require compromises by both the suppliers and users, and don't be shocked when meetings degrade to short periods of loud yelling by all parties seated around the table. That made me laugh (because it happens 8) ) When talking about radio systems, you have hardware, software and human-ware.....

We have a large fleet of the first generation XE Speaker Mics, with Xtreme temp cords. Have served well in the two years being in service. When the XE500's first came out, our regional /\/\ rep gave us two to evaluate. One was given to the Shift BCs and one to my busiest truck company. Within two we...

Thanks for the link to the Nycoil product. That was what I was envisioning, but I don't think it is going to fit into my customer's budget for the project. LMR400 flex may be the ticket, but as you said, I will crunch some numbers to see what the loss turns out to be. Thanks for your reply!

I am working with a Will Burt pneumatic mast for the first time. Installing a portable UHF repeater in a trailer with a 20' mast attached.

The VRS750 is analog, but if your XTL5000 mobile is on a P25 mode it will pass audio back and forth...and actually sounds pretty good.

a1emt

Thanks for your post, CoM. I will only be managing about 120 subscribers, but the alias feature is a big "want" from our end users. Our system won't have OTAP, so that radio management tool may be of great assistance. Heard 7.15 is right around the corner...

Jim

Thanks for the reply! We, unfortunately are not implementing OTAP. The "Exchanging radios" does not occur daily, but many times with new vehicle purchases, redeployment of staff, etc. unit ID's change. We can probably get away with updating the subscribers with an annual "touch" ...

Hello group, my county is deploying an 800 MHz Astro 7.14 Trunked System. I would like our portable and mobile subscriber units to have the ability to display an alphanumeric alias of the unit calling on the system. For instance, I would like "Engine 1" to appear on the display, as opposed...

Hey folks,

I am needing to replace some existing VHF Maxtrac radios for narrowbanding. Looking for an easy "swap" using existing mounting brackets and wiring. Can a CDM1250 slide into the existing bracket and plug into power and 16-pin accessory wiring? Would there be a better choice (m1225, PM400)? ...

Can these be configured with the 800 MHz side running P25 Trunked (XTL5000) and the Futurecom VHF unit running analog? Any limitations to this arrangement like audio degradation or chopping?

I will preface this question by saying I am not an RF engineer.... I have been given the blessing to utilize an unused feedline and antenna to install a 146.xxx P25 amateur repeater.

While we are talking repeater antennas... can anyone offer an expert opinion on the "Low PIM" rated antennas vs. those without a rating. We planned on installing a new VHF DB-224 exposed dipole at the top of a 250' commercial tower, for a 2m amateur P25 repeater. It will share space with t...

+1 on the VRS750 recommendation. I run one on an XTL5000 with very good results in both analog and P25 modes from the XTL.... VRS750 is always analog. Good audio and remote channel steering via PL.

Thanks to all for sharing your experiences! I am definately going to support the continued practice of issuing radios to the individual officers. Another benefit is the ability to rapidly put additional officers on the road in emergencies/disaster situations... and the fact that we had a tornado pas...

Hello group, a few months back in either 'Urgent Communications' or 'Mission Critical' magazine, there was an article that briefly discussed projected service life of portable radios when they are issued to an individual, rather than shared between groups of public safety officers.

Joe, If the Astro Spectra is the same as the XTL series, all the programming is done in the Astro Spectra software. Read your radio with the CPS and there should be a tab for "VRS" (or similar). All of the frequency, PL and settings for the VRS are programmed through the mobile radio. In f...

For your Part 97/FCC fanatics, just look at the busy light before you key up. It really is that simple.

Maybe I am misunderstanding what you want to accomplish, but... isn't there a simple checkbox in the MCS2000 CPS that disables the 'monitor off HUB' function?

Hello all,

I am seeking the Motorola part number of the option board for the R1225 repeater that allows remote repeater setup and knockdown via MDC call alert signalling. Sounds like there were a few different boards produced for this particular line of radios.

My Motorola RIB just broke down during a large programming job. Would like to purchase another OEM box. Are there models other than the RLN4008 ?

Thats the one. Wonder if it works with standard mic?

I will check and see if a mic will plug into the port on the transciever chassis.

Yep, in the Astro25 mobile CPS all the settings for VRS frequency, channel steering, etc. are programmed. My previous experience was with a Spectra 9000 and VRs and I wasn't too impressed.

Thanks for the info. Why does H38 show up in the flashcode if the radio is only capable of 9600 trunking?
