Using my APX8000 on GMRS

[SirJ]

I believe this radio is GMRS, was able to get receive frequency and can hear the radio on my APX, however I’d I transmit with the APX on the same rx frequency I cannot hear any audio from the GMRS radio. Am I doing something wrong ?

also I wasn’t sure if this belongs here or in the GMRS area but since I want to use my radio at work which I know works and I am allowed to id like help using my apx with this radio.

Looks like CTCSS is enabled on the GMRS radio, you’ll need to add a TX PL to the APX.

 

[KevinC]

And to cover me legally, I’m pretty sure the APX isn’t type accepted for GMRS.

As said you have a tone on the Midland. change it to 1-0 and it should work.

Frequencies are here

Tones are here

Probably a power issue. Your 8000 transmits and receives at a higher power than the GMRS radio. Although I could be wrong if programmed correctly.

Okay so change the pl to 0-1 and that should allow the apx to “open” the midland radio ?

ok I’ll try it out at lunch time today.
I don’t see an issue using my own radio except I risk damaging it. But It would just sit in my office because I would rather carry the midland than the apx

Not how that works.

Eww don’t u hate getting radios with coffee stains on the mic

The APX will need to have the 25khz option added for the slightly wider bandwidth that GMRS needs vs the narrow FM that business and public safety use. A NFM signal trying to be heard on a regular FM radio will sound like a whisper and may not open the squelch or modulate the PL strong enough to be decoded. As stated before, the PL needs to be the same or turned off on both radios.

The APX will decode PL tones down to 100hz of deviation. The narrowband standard is around 300hz Make them both carrier squelch and try again.

There is no such thing as a "25khz option". All legitimate APX sold in the U.S. that are capable of VHF/UHF come with Q507 - 12.5 kHz FCC Mandate in the flash, which will not be removed by any legitimate means. It's moot, as the APX and CPS know which specific frequencies are exempt from the narrowband mandate, and can be programmed with 5 kHz transmit deviation. These include the ham frequencies as well as the GMRS frequencies.

Nothing special needs to be added or done to an APX to allow for wideband deviation on the GMRS channels.

Not sure where you got this idea, but a swing and a miss...

Doesn't the Midland radio need the Part 90 EID to enable its codec to hear an APX?

And to cover me legally, I’m pretty sure the APX isn’t type accepted for GMRS.

Nevermind. KevinC is correct.

This radio right here is pure Luxury, APX got nuthin on this.

 

[SirJ]

So the midland shows a pl of 8 what would that be on the APX because I’ve never heard of a single digit PL
