• 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.

Kinda losing my mind on what else could be wrong on this. Got my trunking profiles set up. Using nas with hidden trunkgroups. I can occasionally pick up transmission but not everything, comparing to a G5 thats grabbing everything. Any ideas?

because the G5 is designed to be a scanner. When using an APX as a scanner your asking the radio to do things it is not designed to do. I had two identical Motrorola radios set up for NAS scanning the same 10 talkgroups, there were times one would get the transmission and the other wouldnt. NAS is tricking the radio to scan Talkgroups from an analog scan list.... also C4FM vs CPQSK Is it simulcast? lots of varibles

This couldn't be more incorrect.

Not accurate. The APX is using a Multi-System Talkgroup or Intelligent Priority type scan list, not "an analog scan list". Those scan list types were explicitly designed to scan between conventional channels and trunked talkgroups. The fact that the radio sits on a conventional channel while in non-affiliate scan mode doesn't mean anything, it could just as well be sitting on a talkgroup using the same scan list types.

Under Unmute/Mute Type, i changed it to Unmute, Std Mute and it started opening up more. Previously was on Unmute, Or Mute.

This setting makes no difference to no-affiliate scan, unless you're causing the radio to hang on the conventional channel for whatever reason.

The conventional personality should be set to whatever is necessary to keep the radio off the conventional channel and on the control channel.

Check Scan Wide > Trunking > System Search Time. Set to 255.

I was thinking the conventional was grabbing and monitoring for whatever reason, even though its a random non-used frequency and a random PL assigned.
I'll give the system search time a try. Thanks again for your help!

Interesting. I suppose I've never had that issue since my NAS conventional channels are set to astro and unmute rules only apply to PL. All my nas scan lists are trunked talkgroups
That really fixed it? Are you scanning any conventional channels or the scan list is all trunking talkgroups? If the system search time is set to the default of 2-3 that would somewhat explain why. If you only scan one system per scan list a system search time of 255 would be appropriate
If you notice it still slightly off or clipping, I have a few other suggestions I've come across in NAS experimentation that cause missing transmissions

System search time helped quite a bit. Also trying to figure out the best way to get the channel id for different systems.

My APX 6000XE and 8000HXE never miss anything actually my G4 and SDS miss stuff all the time. NAS is tricky you have to know what your doing one little thing checked or unchecked or entered wrong can make a world of difference.

My APX7000XE Luxury Transceiver is the finest piece of equipment available for monitoring my local P25 trunked system! Never misses a call and it's always with me, wherever I go whether that be at the tennis club, yacht club, a drive along the coast in one of my Ferraris, or participating in rescue drill operations will the local sheriff's office, with whom I am closely affiliated.

I was going to try, but I can't top that.

Mine comes in handy whenever the Cost Guard needs to land their helo on the roof of my crib.

Buy an RTL-SDR and use SDRTrunk or Unitrunker, nothing more accurate than that
I tried using unitrunker, but something wasn't working right. I'm thinking of giving pro96com a try for getting channel id's.
