At the time this page is being designed, there is no information online about this transceiver. This is a Kenwood P-25, Model TK-5820K. Its original intention is to be used for commercial purposes, but will function perfectly in the UHF amateur band.
Currently, there are few of these available and tend to be priced on the high side. As more become available, prices will drop accordingly.
Success programming this transceiver was by trial and error, but with some prior programming experience. While general programming is straight forward, some features are hidden in plain sight, as Kenwood has their own terminology.
Information and instruction for this radio is being offered on an intermediate level. It is assumed that you have some programming experience, but may need to know some tricks.

Enjoy! I hope this information is helpful for you.
A RECENT DISCOVERY - I have several Kenwood commercial radios and through doing a frequency check with a Tek-Tronics analyzer, all these radios were sustantually off frequency by as much as 1kc. That's beyond acceptable. In the Kenwood software, there is a simple alignment tool. Now, all the radios are within 1, or 2 cycles from dead on frequency. Why were they so far off? I have no idea, but they were, by the same amount. Gives wonder to factory standards. I also want to mention that alignment of the P-25 radios are more complicated. The analog models are very simple to correct.
