    Default Problem With APX TX audio! Fixed!

    We have 2 APX7000's that are 2010 models for use in our Comm dept. I was having complaints that my audio was muffled and just overall poor audio. Of course because I was never on the receiving end I never had a chance to hear just how poor it was and really could not tell on our Service Monitor that there was an issue. I should of investigated it along time ago, but time to investigate the problem I did not have. My priorities are not as important as others peoples priorities, LOL. We have a few later model APX 2011's and 2012's in service and audio sounds great, so I just assumed that the few that had complained, just need better hearing aids. And being a tech we really don't talk on them enough like our field users. The other day I had a complaint from a coworker that he had a hard time understanding me. Although he is not a tech he is a gun carrier, he has always had an interest in radio's, and always curious and asking questions on how the system works and such. And he is VERY critical when it comes to audio quality. I knew at that point, maybe I should just take my work home and investigate.

    Problem found under (Noise Reduction Configuration) and then (Int Mic NR 1) to see the data you have to put the CPS in EXPERT mode Under the VIEW tab at top. I found my data except for the Global Noise Reduction was all zero's. I found it odd that it was all Zero's. So I pulled up an archive of one of the newer model 2012 files i had, and compared, low an behold the later model archive's were not all Zero's but populated with ton's of HEX data entries. HMMMM,,, at first i was going to drag and drop, but found if I added a Second (Internal Mic Noise Reduction Profile) creating a new profile called (Int Mic NR 2) that the data was NOT zero's but was populated with the same hex data as the newer 2012 radio's. So I deleted (Int Mic NR 1) and then renamed (Int Mic NR 2) to (Int Mic NR 1). Wow what a difference in audio. With the settings set at ZERO's I don't believe any of my advance audio reductions settings were working. I can now tell a huge difference between OFF, NORMAL and AGGRESSIVE. I had always had different profiles set up for Wind noise or background noise or both. And now it works,,, both analog and digital sound so much better,,,very impressed!. Kinda embarrassed i didn't investigate the problem earlier on. Heck there was probably an FSB released I missed for the 2010 model's with this issue. As it was shipped from Motorola set this way, and never messed with the expert mode.

    So if any of you have had complaints, take a look at the setting could be the problem. Also check out the custom features you can do Under radio profile's with expert mode enabled. Kinda cool to tinker with.

    PS, Does any one have any information on what all the hex settings are and mean in the noise config menu? It may be in the advanced service manual, not sure though. I will take a look when I get back to work later this week.

    Warning!!!!! make a backup archive, just in case you jack the hex data up. Better yet don't even mess with the HEX data.LOL


    Sorry so lengthy, I apologize. Just thought I would share. Every Detail,,LOL


    HAPPY NEW YEAR!!!!! To everyone on the Awesome P25.ca site.

    Can you share the hex data? That would be helpful for those of us who want to do compares Thanks.

    Ext Mic NR 1 has same values.

    Warning! all values I have giving are in HEX. There are decimal values there also, do not confuse them.


    I believe when you add a Mic Noise Reduction Profile, this data is being generated by CPS. You can do an easy check by creating a new profile and comparing them, hitting the alternate view button makes it easier to compare values.


    I have gotten ride of my early releases of the CPS for APX due to hard drive space, i am curious to see if these values are different in earlier versions. If someone is still using a version older that R09 please let us know what you find, for these values. Just add a new noise reduction profile, and post the data. Always remember to save an archive first,,,just in case.

    There are also long strings of HEX data under the Global Noise Reduction List. My Ext Mic NR 1 and Int Mic NR 1 match yours.

    Oh for the good old days of plain old mic gain in the RSS.
    Good information guys, thanks.

    I looked at my Global Noise Reduction Lists and compared. At least they were not all ZERO's.

    There is a difference between my 2010 radio and a 2012 radio in hex data. Here are the values in Hex.

    I tried to drag and drop 2012 global to the 2010 radio, but wont allow it, however Cntl-C and Cntl-V work. You cannot add a profile like you can in Noise reduction profile. Plus sign is greyed out on Global.

    The all F's on the 2010 radio EQ1 and EQ2 vector cont. Kinda concerns me a little....HMMMMM

    I used moetorola's 2012 values in my APX (which had all 000000) and it made a massive difference in TX audio quality, in the profiles for which I had the filters enabled.

    The most significant improvement was to the Extreme One-sided Noise Reduction (QA01833) profile.

    I wonder why Motorola has not automatically implemented these changes in CPS/firmware updates. You'd think the default values would automagically change along with the progression...

    If you had all zero's, please post the date of the radio's manufacture date. May need to open a case on this.

    I bought mine from an alternate source in spring 2011. Factory parts (non-ALT) inside, but unknown mfg date.

    Nice. My audio settings had different hex values for the global, but the others were the same as that defualt codeplug (I have a XE, but made a cp copy and changed them to that default). Anyone have a default depot XE CP to compare?

    Just another update.... the values from that default cp on the XE reports to the same guy I talked to the other day as much improved. With the XE RSM I uncheck AGC for the external mic and put a value of +6 in for analog and the audio was reported to be much shaper and clear. No other settings were changed.

    I also need to add that on the custom settings, internal mic source on mine was set to mic 1 only (IIRC) and when switched to Full Automatic that seemed to help with the RSM detached.

    I guess the other moral of the story is that if you get a non-factory APX, these are settings to look at (and completely forgot about the expert mode)

    Check your inbox for the XE codeplug. I'm also moving this discussion to that thread.

    FWIW again, the global values between the XE and non-XE7000 are different. The internal and external mic values appear to be the same...even with xtreme profile. I did notice that (at least on my XE as it was delievered) the dual mic setting was not enabled for "Fully automatic" which did seem to help (helps to have dual mic enabled on a dual mic radio).

    I had a conversation with a guy last night and used both global settings and he noticed no difference. The +6 for the external mic gain under a profile did make a big difference in audio quaility with the XE RSM.

    I'm sure this is all duplicated information now...but those are the results so far.

    I know this is a somewhat dated reply to this but I just saw this thread today. Checked my radio and lo and behold, all zeros on INT MIC NR 1. Seems most all of the faulty info is the same as the OP but was not able to do further testing today. My radio TX sounds like *** compared to my XTS2500i both P25 and analog. Radio S/N 655CKXxxxx UHF R1/7-800 shipped original with FW 2.0.0 on 01DEC2009. Had to send it back because /\/\ forgot to turn on the dual band operation that I paid for. Radio since flashed up to 8.05 host/DSP. I am looking at the DEFAULT CP as I read the radio and saved before provisioning to my system. I see the same thing in CPS 7, 8 and 9. Radio last wrote with 8.01.

    Thanks for the work on this!

    Excellent post! I had a look at my 2010-vintage Seth special, and sure enough all of the advanced fields were zeroed out.

    This combined with AGC disabled and +3 fixed gain has finally given me a radio that no one complains about.
