APX Programming Questions

[Markb]

Hello All,

My agency is preparing to roll out APX series portables. I have been doing all of the programming, but I have 2 things at the moment that I am looking for help with:

1. Analog audio seems muffled. This is irrespective of personality and/or other hardware being used (our old Kenwoods and repeater/simplex). To my knowledge, I do not have any audio profiles enabled and HearClear in disabled/doesn't make a difference (we don't use commanding in our system). I've tried numerous parameters in CPS and can't get it to clear up.

2. We use the MPL function heavily. I was told that there's a way to keep the PL tone alias on the screen for more than a few seconds. Is this true and if so, how?

MTIA,
Mark

APX6000 ? 8000 ? 1000 ?

8000

My APX8000H flashed with FW R21.66.00 having the Radio Profile and Noise Reduction set to defaults has excellent analog audio.

Is it possible that your muffled analog channels are using either 5 kHz / 25 kHz or 4 kHz / 20 kHz wideband and that your associated conventional personalities might be set for 2.5 kHz / 12.5 kHz narrowband?

I will check on that. All of our stuff should be narrow-banded in accordance with the old mandate, but I will confirm that part of my programming.

Thanks!

OK. I didn't know if the audio complaint was on known narrowband services or was perhaps Marine VHF, GMRS, or Amateur frequencies and thought I'd interject the possibility of an incorrect bandwidth setting.

I deployed a few APX-8000H (Firmware R21.03) With the following settings:

Microphone/TX Settings:
Group Setting: Normal for both
Gain/Sensitivity: Custom, Uncheck all AGCs, Set to 0 for all Fixed Gain slots
Digital/Analog Balance: Unchecked
Audio Equalization: Low (-3) Mid (3) High (9)

Speaker/RX Settings:
Audio Equalization: Set to custom for both. Analog High (4) Everything else set to(0)

Let me know how that works out for you. Users are happy both using the built in speaker/mic arrangement as well as accessories stating excellent TX/RX reports on both P25 and Analog 12.5. Ensure that you have this profile enabled under all channels as well, or it will automatically default to "Last Selected"
