• 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 TK-8180H-K2 power levels?

I purchased a few of these in reserve a few years back. Now retired, I am deploying them. I got the first one programmed quite easily with the KPG-89DN software, which is a lot like a simplified CHIRP. The unit has very clean sound on Low power, running thru a Tram 1481.

I set all freqs to Low power for this testing phase. I pored thru the Kenwood manual and see no specs as to what power outputs are Low and High. A search here in RR was also unfruitful. Running in 460.nnn mhz, does anyone know what the Low level represents? I know High should be about 45w.

Another curiosity is that other threads here mention that a narrowband TK-8180 can't run wideband. Not sure of the build date on mine, but its firmware is 1.22.00, and in KPG-89DN I can set each channel to wide or narrow. Perhaps that means it was built before 2012? When I set up the others, I'll learn more.

TK-8180:
High Power = 30 watts
Low Power = 5 watts

TK-8180H:
High Power = 45 watts
Low Power = 10 watts

It's not the radio build date, it's the firmware version.

However, Kenwood did offer a wide band license for the KPG-89D software that would restore the capability to program wide band.

I've got a TK-3180 sitting next to me. The TK-2180/3180 uses the same firmware files and same programming software as the TK-7180/8180.

Mine is showing firmware 1.22, and it'll do wideband.

Same thing I am seeing. I'm glad, as GMRS is 12.5k wide. Hope to QSO with friends who don't have ham.

GMRS is allowed to run 25KHz. Most repeaters are 25KHz. Most licensed GMRS users run 25KHz.
The FRS radios that share frequencies with GMRS are 12.5KHz.

If you run 12.5KHz, others running wide band GMRS may tell you your audio is low.

Now I am confused as to what Wide and Narrow are on a TK-8180N-K2. 25khz and 12.5?

Looking at the chart of GMRS channels sorted by freq, there is only 6.25 between most of them, which would be 12.5kz bands. The ch16-ch2 gap is quite slim at 3.75khz. Sample below, FRS excluded. I'm licensed on GMRS too.

Traditionally/currently:

Wide = 25KHz wide channel, 5KHz deviation.
Narrow = 12.5KHz wide channel, 2.5KHz deviation

On the Kenwood radio, setting the channel to "W" on the far right side of the channel/zone programming screen will give you the wide channel width. N = narrow band.

Yes, but you are confusing the spacing between the individual channels with deviation. Two different things.

Thanks, yes I was ignorant. I suspect many old-time hams still think mainly of the original 6 GMRS simplex freqs before FRS got folded in. That is the case for my local Expert, from whom I get advice and buy used equipment.

I got this list below from the FCC horse's mouth.

Channels​

There are 30 GMRS channels with a bandwidth of 25 kHz (20 KHz authorized bandwidth) or 12.5 kHz as outlined below:
