• 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.

Has anyone ever encountered a difference between the radios receeiving signals. Specifically Motorola radios picking up the signals & VP6000 not hearing anythng?
It is a Motorola P25 800Mhz system, the radios have all been bench tested on different Viavi test sets and passed. Have spoken to othere in different areas and they mentioned same thing.

I’m not a Kenwood guy, but I’d imagine they would be pretty darn close in their specs, both RX and TX.

Are they not receiving at all or are they missing calls or something else?

They not hearing the calls. Its not an occasional happening. Users reported different locations & in differnent strength areas. Assuming it must be the programming or difference between motorola & kenwood.

Sorry they hear some stuff, just miss some calls when the motorolas hear them.

Again, not a Kenwood guy, but if the system is simulcast are the radios set to LSM/CQPSK (assuming Kenwood has a setting for that and doesn’t try to automatically decide)?

No nothing as fancy as that. Just a straightforward astro system. Did call EF Johnston and nothing from them. They not aware of anything.

Have you checked the modulation type as mentioned earlier?

I don't have access to it, but this sounds like maybe checking to see if you are running the latest firmware in the radios would be a good step.

Unrelated, but I had a bunch of early NX-410's that were giving me issues with missing calls on my trunked system. Kenwood fixed that in firmware and they've been fine ever since.

mmckenna is right, on a TRS I have seen a radio trunk off to a distant site that it then cant access...update fw and it fixed it...forgot about that

Uh...any astro system will be programmed for either C4FM or CQPSK. That the modulation of the system. You need to know that to do it with the Kenwood. Unless its a single site it is most likely CQPSK. Ive run into this with other vendors on both P25 simulcast as well at trunking.

And frankly, I program pretty much all radios for LSM instead of C4FM. It seems like that works on everything, even though it's meant for simulcast. We've also seen lots of problems with radios going to sites they shouldn't. That seems to be an issues more with the system or with an obscure setting in s/w somewhere.
Current f/w for Viking is 8.40.20, or .21 for the VP8000.

Have zero issues with Viking radios on our A25 2022.1 M-core 15 site LSM system. Your system owner/support team can and should be driving your codeplug/template development. Get with them and confirm, but most likely mod type should be set to CQPSK.

Thanks for the input guys, will follow up. am going to check codeplug then reach out to EF Johnson again.
