I confirm this. I am using Zone scan mode and Kenwood lands on any DMR activity, including IPSC marker (no voice). Motorola just skips all activities that do not match to channel criteria (color, GID). Kenwood lands to any matching air interface carrier. This issues also affects P25 but not only DMR!

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.
Kenwood NX-5000 problems, lacks, suggestions and improvements

Issue # 12. Very similar to isse # 4, but affects DMR.
Kenwood NX5000 will stick on ANY (DMR or P25) valid digital interface transmission and will land scan (green LED = ON). No other things, like Group ID from RX List, are compared with actual signal. It could be even data, GPS or IPSC marker - doesn't matter. Radio will keep silence and will remain landed. If transmission repeats during active scan resume timer (e.g. when you're come across Motorola IPSC repeater), you will get radio that 'seats' on channel virtually forever. YES, radio will never resume scan.
I reported about similar issue here https://forums.radioreference.com/2665838-post9.html , but nobody understood my point. And most active RR dealer just said some crazy things and actually did nothing. They do NOT understand how radio must work - both dealers and Kenwood.
Issue confirmed by 3 other people: here https://forums.radioreference.com/kenwood-forum/352144-nx-5000-series-dmr-programming-question.html and here https://forums.radioreference.com/2754499-post98.html
It's very sad, but all looks like Kenwood and dealers don't use their radios and have never dealt with normally working radios, like Motorola.

So, at the very best NX5000 radios are actually only NXDN/Nexedge capable. I can't now imagine putting one on a P25 TRS which was my original plan. I would never be able to trust it.
Shouldn't some Kenwood engineers be disembowling themselves -- along with board of directors?
DMR (&P25?) not ready for Prime Time
I did the same. I utilized List Scan a little more strategically as a very poor work around for broken scan function. I believe the Mototrbo radios limit size of "Receive Group" to 15 or so I.D.'s while presumably Kenwood could scan a list of over 1,000 GID's. My list has 62 GID's and Kenwood has no problem or delay scanning the GID's. Still I have the problem of radio freezing up and being inoperable. I created a different codeplug and for awhile it seemed more resistant to freezing/locking but after a few hours it also locked up (sitting unattended-no TX or playing with controls). I really need P25 but if it is the same I am reluctant to pay for and install it. I need several P25 TRS radios as well but afraid they won't work reliably on State system. But as you (N3AAG) said previously, all we can do is wait and hope Kenwood fixes it. I want to do something constructive but have no idea how. Knowing my luck they will probably fix it right after I buy more XPR & APX radios!

No. You must work through your dealer.

Issue # 13. Actually not a serious issue, more likely improvement request.
Here is how audio recording looks like. As you can see, no any alpha tags - no zone name or number, no channel name or number. You only have timestamp. You have to find what you need just by time. It would be great to see here any Zone and Channel designator. Ideally, Zone and Channel names.

Issue # 14. Ugly (or just broken) RX AGC! Very very serious issue!
It's absolutely amazing, but RX AGC works ugly (absolutely improperly). When turned ON (High position), radio still sounds with defferent levels of audio, and does NOT level anything. But as bonus, you get very strong clipping in NEXEDGE, P25 and DMR! Yes, all 3 digital standards affected. And doesn't matter what are you lisen to - which network, which radios and with which settings. Everything will be clipped and distorted. Meanwhile, analog sounds well when AGC is high.
Here I will show you what happens. All recordins are from microSD card, built-it recording featire. 2.10 firmware. AGC=High.
So, never have AGC turned ON! NEVER UNTIL FIXED! RX AGC will destroy RX quality. Set it to Off and enjoy normal sound and different audio levels at the same time.
I can't believe, that Kenwood did it, released to public and NEVER tested it. Absolutely non-working features like RQ Equalizer and AGC. Unbelievable!

AGC issue reporting
Mr. Justice,
Please provide the following information:
Channel information, tx mode, rx mode, bandwidth of your base line, bandwidth used. equipment used to generate the signals, equipment used to decode
the signals (service monitors), what was your base line for the information to depict that this is Kenwoods error and not yours. Provide your codeplug for others to try and to see it themselves,
AFTER YOU GET WITH YOUR DEALER WHOM YOU BOUGHT YOUR RADIO FROM
In order to correct the problem, you have to outline from start to finish the how's and the what's. This is required for ANY radio manufacturer to decipher if it is human error or equipment error.
You're solely out on a witch hunt for whatever reason, but you lack the ability to outline it for others to test your theory or hypothesis. You do not provide material evidence needed to duplicate. Get your dealer on here to back your statements up. Give us some credibility here please.
Please be more detailed in your findings rather than blasting Kenwood thinking
they have all the time in the word to read what you post here.
You have been asked and warned multiple times, yet in your thoughts and sayings, you don't have the time to work with your dealer, who is to also report such occurrences like this, to their Rep's, and to Kenwood Tech Support. IF you have a hearing assistance device (HEARING AID) and this is what you're complaining about, then SAY SO. Our crystal balls don't magically make things up, nor miss-read what you write. If your a Handicap-Ham, then say so. If your legally blind, say so. For all I know, you could be
Stephen Hawkings pulling my leg.
Please, and I will say this once again as you have not learned it yet, Detail your findings, show more supporting
factors, and TURN IT INTO YOUR DEALER. Then share your findings with the rest of those here.
Simple put, talk to your dealer.
Fair enough?

Looks like Kenwood run into serious problems - their DSP code coders are dummies. Here are a few facts:
- Analog TX signal is weak (requires +8 dB gain to provide normal deviation)
- Analog TX signal doesn't have proper emphasis
- Analog TX signal doesn't have emphasis control at all (YES!)
- RX AGC is broken and dramatically clips signal
- Both RX and TX equalizers doesn't work at all (and it's know issue during more than 1 year)
Not tested TX AGC yet, but I can suppose that it's the same.
I've never seen so raw and ugly DSP realization even in Astro Saber from VSELP times. Looks like DSP code was written by student in a few nights. Or their DSP coders just left their R&D team or was fired. I don't know, but it would be believable.
It’s so sad. Good hardware, good design, brilliant ideas! But poor, raw and buggy firmware. Especially, DSP code.
No one law enforcement agency will buy such a product if it has not gone crazy.
P.S.
Any product owner can test and confirm everything from what I mentioned.

Show me the proof you're smarter then kenwood.
If you can not provide the proof, then please see your way
off this list and off this forum,
last warning!
Might I suggest to you that if you don't like what a member is posting, that you put them on your Ignore list or stop responding to their posts?
Harris radios now coming from the factory have the newest versions of firmware loaded that require the latest revision of RPM,which requires a system key be entered for any P25 system to be programmed.Unlike Relm,they won't be providing any unauthorized individuals with 'generic' keys for Rx only. Only radios with old firmware touched with earlier revisions of RPM can still be programmed without a system key for (non-affiliate) Rx only on P25 systems.

And this is in keeping with the NexEdge trunked systems. An unaffiliated radio will not receive trunked system traffic. Disabling a radio in the system not only blocks it from transmitting, but also receiving. If a radio has not be enabled in the system with a valid radio ID (and in my case) a matching ESN, it's a no go.
While I'm not against someone listening to my system, I have no desire to make it easy. Appropriate talk groups get encrypted, anyway. Scanner listeners, fine with me. Other public safety agencies, it's pay to access, just like all the other legitimate users.
DMR BUG FIX Firmware update being tested.
There a few people who I am working with on the DMR issue, I have sent you a private email with
instruction. Please get back to me when you have completed the instructions and let me know what you
can find so I can report back to Kenwood before they release the firmware next week. I need to let
them know by Tuesday.
It is NOT on dealer tools at this time.
If you worked with me between Jan - March on this, and did not get my email, please email me tonight for the instructions.
Thanks in advance.

i will be on TAC310

Group, Have any of you guys checked your TX power levels "as delivered out of the box from the factory" on your NX5700, NX5800, or NX5900 to see if your radios are transmitting their advertised maximum TX power? I just checked my two units and they are NOT putting out what they should be. My NX5700 advertised at 50 watts but only getting 44 watts, my NX5800 advertised at 45 watts but only getting 32 watts. I sure hope this is not a defective unit straight from the factory... What have your transmitter power level results been from the factory on your radios? Doug
