• 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.

Hytera and Motorola have their own version of single frequency repeat in which a radio can do a skinny mesh mode by receiving on one time slot and repeating it on the other time slot. Hytera only puts the repeat function in one of their portables while motorola uses it with a single frequency extender device or a repeater. On motorola subscriber unit you have to do split color codes: 1 for Tx and a different CC for Rx. There is more involved since the suscriber units can talk direct when out of range of the single freq repeater and then when they come into range they go through it seamlessly without interruption (I don't know how that works). I realize that my NX5 radios cannot do split CC so will not interop with moto extender or split TS for hytera. I ask all this because last week one of the captains in our state wide task force was quizzing me about it. We were in fact talking over the radio so we didn't get into any detail but I realized he wants to use that capability going forward. I thought I'd ask some questions here before I get pinned down by him later on. Since they deploy to all kinds of emergencies it is easy to see why having ability to use a portable or mobile radio instead of full blown repeater (duplexers etc) would be extremely attractive (even lifting unit with one of their drones). The TF unit near me is already buying some Kenwood gear with my encouragement and statewide they are buying DMR radios (don't know the numbers) including some chinese radios for hand out cashe radios (this I did not encourage even though as a taxpayer I'm sensitive to what my state spends!). I hope after this pandemic the chinese manufacturers are on everyone's s... list. I for one will not be recommending hytera even though at the moment their solution might be the best. I guess the hytera must be able to "split" Tx and Rx time slots but I don't actually know. Anyway, this capability is not going to disappear so I'm wondering if Kenwood has any plans to implement some version in their radios? I believe it would require only firmware to make it happen with existing hardware.

while this does look attractive, there are no plans to doing this, as Kenwood follows ETSI standards mainly, and this function is not a set in stone standard at this time.
I will pass this along to my discussion group however.
Thanks!
