• 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.

Does anyone know if the TK-3402 LMR is identical to the TK-3402 PROTALK Radio except for the PROTALK software? Is the TK-3402 PROTALK available with a 400-470 band split?
I see a lot of PROTALK radios for sale but nothing on the LMR version.

I've been working on this with someone else, and here's what we've figured out....

Electronically, they are the same. Same FCC certifications, all the part numbers I've looked at are the same, at least when comparing similar wattage models. The TK-x400 models appear to be the same electronically as the TK-x400 protalk models (2 watts). The TK-x402 models appear to be identical to the TK-x400 models with the only difference being in the RF board having to do with the 2 watt vs. 5 watt ouput.

The firmware is the same between the TK-x400 and the TK-x402 radios.

The original product release info for the x402 protalk radios mentions that they can be programmed using KPG-160DK.

So, the guy I was working with on this tried pusing the non-ProTalk firmware into a ProTalk radio and it took it, however it still says it's a "protalk" radio. So there is something. I haven't heard any more about this, and I don't have one of these radios myself or the time to work on it.

Seems like if all you want to do is take a ProTalk radio and program your own custom frequencies into them, it can be done using the KPG-160 software.

The non-ProTalk UHF radios are available in 450-520MHz versions AND a 400-470MHz version.

The ProTalk UHF model is advertised as having 90 channels preprogrammed between 451 and 470MHz. Looking up the FCC ID for the Protalk radio (ALH435002) shows it as being a 450-512MHz radio ONLY.
There isn't a 400-470MHz version that I've found. The physical internals of the RF portion of the radio would be different, so this isn't just a programming change.

I wasn't aware that the PROTALK was a 2 watt radio. I am looking for 5 watt units. I would like to purchase new ones if I can locate a Kenwood dealer in Colorado springs. I would like to get some used TK-3180's but I need a couple of idiot proof units.

TK-3180's can be locked down pretty well in their programming. Disabling a lot of the functions would just leave on/off volume, channel select and PTT.
Benefit would be that you'd have a common radio platform, same batteries, accessories, etc.

If you get the non-protalk TK-3402's, they are 5 watt, and can be programmed.

If you are just looking for dirt simple radios, the used TK-390 UHF portables are running around $100 - $150 on e-Bay. Much more durable radio in my opinion.
