APX7000 and Public Safety Mic PMMN4047A

Postby JimmyL1011 » Wed Jun 08, 2016 11:28 am

Howdy Gang:

I just got my fancy new APX7000 at work which replaced the XTS5000 with the Public Safety Speaker/Microphone. The APX7000 is used in the hand-held only configuration and while the radio is great, taking the radio in-and-out of the holster is rough getting used to. As a result, I purchased my own PMMN4047A public safety mic. My question is: can I just take the antenna off the radio housing and move it up to the PSM or should I get a separate antenna?

Our system is analog, conventional, non-encrypted UHF. Even though the radios are 700/800 MHz and GPS capable, those items are not enabled. I believe that the software can be modified to send the radio RF to the handheld housing antenna or to the PSM antenna. When one attaches a PSM to an APX7000 does the radio "sense" the connection and send the RF to the PSM or does it keep sending the RF to the attached antenna?

Obviously, not being my radio, I'm a little squeamish about reading the radio and plumbing it's secrets so I thought I'd ask the brilliant minds and the BB radio forum gurus first.

You will not get UHF routed to the PSM on that radio. Any dual-band radio with 700/800 will ONLY route 7/800 to the PSM, leaving GPS and the secondary band on the radio's antenna. This is a hardware limitation and cannot be hacked or modified.

If I remember correctly it also depends on which band is the "primary" as to whether the RF would be routed to the public safety style speaker mic. You can only find this out by reading the radio's cp to see how it is configured. Motorola doesn't support VHF going up the cord but in the past has routed UHF to a shoulder mounted antenna previous models.

Our radios are flashed for 7/800 primary and UHF1 secondary but for some reason UHF1 shows up as primary in test mode. Either way 7/800 is what gets routed out the side RF connector.

APX8000s supposedly don't have this limitation but I haven't had one long enough to play around with yet. This was supposedly done for vehicular adapter functionality.
