Kenwood TK880-2 to 880-1?

[esb]

I got a few radios in trade, including a Kenwood TK-880-2 -- meaning the 485-512 MHz model. I have an 880-1 (which covers the GMRS frequencies) and I love it.

 

Forgive what I'm sure is a whole lot of misunderstanding in the request that follows, I'm still relatively new to amateur radio:

Is there an easy way to modify the 880-2 to cover a lower frequency range -- swap crystals/semiconductors?

 

I'm likely going to sell the 880-2, but if there's an easy (I'm handy with a soldering iron) way to get it working on a frequency range I'm licensed for, that would be fun too.

Simple Answer - No

Suggest You Trade Or Sell The 880-2.

Or keep it and use it for spare parts that are common with the 880-1 version. Sometimes finding spare parts for old radios is nearly impossible. That's why a few guys keep junk chassis's around to pick over.

The 880-1 are nice radios..   I have two and they'll never leave my sight

Or just “force” it to use one of the other UHF band plans which are selectable in the software. It will complain when you go to program it, but it will allow you to do it anyway, and it will work. I’ve done this numerous times with various Kenwood VHF and UHF handheld and mobile radios without issue. 780’s / 880’s / 863G’s, etc, etc.

I’ve also tried it on various Kenwood HT’s. Some you can “push” to operate way out of band, others not so much. For example I have a NX-320 450-520 band spilt radio. The PLL won’t lock below 443 when I tried out a sequence of test frequencies. It does seem, from my experience, the narrower the band spilt the better luck you have running farther outside the official range.

If a radio is available, some come in various band spilts so be VERY careful, with the 400-470 band spilt that’s perfect for Ham and GMRS. This seems to be more frequently found with the FM/Digital mode radios. Those are the ones I watch out for on my favorite auction site. Of course you can’t use digital voice on GMRS, at least not yet so you’re stuck with FM, but perfectly legal on the Ham bands.
