I had been looking at various Kenwood TK-880s and also a TK-863G, when the Motorola M1225s popped up for a good deal and I bought one of those. Then 2-3 days later one of the TK-880s (this one a high power version) had its price reduced and I jumped on it.

 

It arrived today. The M1225 still hasn't arrived, but hopefully it will be here tomorrow. The TK-880H powers up, shows Version 1.50 and then "unprogram." I was hoping it would still have some frequencies in it so I could test it into a dummy load. I was also hoping (but not expecting) that it would have FPP enabled. No dice in either case. Oh well.

 

So I ordered a usb programming cable from Bluemax49ers. When it gets here I'll see about programming it, and also enable it for FPP. Although with 62,500 possible channels (250 banks of 250 channels) it's doubtful I will need FPP very much.

Looks like you will also need the Kenwood KPG49D software. Really easy to use...  Since it is a firmware 1.5, you may see an alert that it is not a software target radio.  Disregard that alert and continue.

 

Hint: when you get the software loaded, the radio connected to your new USB cable and the COMM PORT checked as active from  the setup tab... hit the "MODEL" tab in the software menu screen. Click on "Model Information" and a drop down menu appears.  Normal settings would be -

Model Type: TK880

 

Frequency:  450 to 490

Radio Format:  Conventional

Option Board:  none

 

Fleet Sync Enhanced Function:    (Important that this check box IS NOT CHECKED)

Thanks, Gary. Sounds like you know the ins and outs of 880s.

I think I read somewhere that these early ones work better on the ham band than Version 2 radios. Do you know anything about that? It would be great if it would perform well on GMRS and 70 cm.

I can not address that question directly because I have no 'ham' radio experience. However, the Kenwood commercial radios are just that - designed for Part 90 and Part 95 Commercial use. That may answer your question.

Keep us up to speed on your progress... and as with all used equipment, the transmitter should be tested 'officially' for frequency tolerance compliance before connecting to a broadcasting antenna.  (Part 95.1765).

Most of the world only uses 430-440 for ham radio, and business/industrial starts 10 MHz below the US. Kenwood makes radios for those markets, too. So they actually are designed to work there.

What I read somewhere is that the firmware in V2 880s makes it more difficult, but that V1 880s program down to 440 without issue.

 

My TK-805Ds program there. I'll try it with this 880 and see how it goes.

According to data sheet, TK-880 Type 1 is aligned for 450-490MHz, Type 2 is for 485-512MHz, Type 3 is 400-430MHz. I have TK-880H-1 v2.0, and there are no problems programming ham bands into it.

Thanks. To clarify, I was referring to Version 1 vs. Version 2; not Types 1-3. Thanks for verifying that your V2 does program into the ham band. How well does it perform there? Did you have to realign it?

I did not realign it. I just programmed several local ham UHF repeaters into it. I can easily reach repeaters, signal quality seems to be good. I do not have equipment to see if there is some excessive distortion or any other problem with the signal.  One day I might check it with the power meter.

Thanks! I just programmed mine with one group of basic GMRS channels, a couple of days ago. I plan to go back in and add more groups soon, and I'll probably include some 70cm test frequencies.

Update: It wouldn't receive below about 444 MHz. I tweaked the receive VCO and it now receives down to 442.000 or a bit lower. It transmits at full power down to about 442, as well.

I now have a V2 that I tweaked the same way, and it also works well on 70cm.

RCM, If you need, I do have firmware (Cant remember which one off the top of my head but it does update the radio options for version 2 units) for the 880, I can also explain how to enable FPP, but in all honesty its a bit difficult (I could never figure out how to do it.) All I use are 880/380's so if you need anything give me a shout.

Thanks. I have it sorted out now, though. My 880s now work fine on 70cm as well as GMRS, and I have also performed the hardware mod on all of them and enabled FPP.

What is the hardware modification to enable FPP?

Removing the R614 is the hardware mod for TK-880 Ver2.0:

Is this modification necessary to enter pl tones from the panel?

Yes, it's needed to program anything from the panel. With this resistor present, pressing D when powering up will not bring you to "SELF PROG" mode. But only for Ver 2.0 of the radio. I've read that on version 1 you can enable self-programming from the KPG49D software. I cannot confirm or refute this claim, I do not own Ver 1.
