I received my TK-880 day before yesterday. Although the KPG-49D RSS complains about RX and TX being "out of range" receive and transmit on a 442.200 repeater is just fine.OK. Just so you know, while a 450+ TK-840 covers the whole UHF ham band [my 4 do anyways] a 450+ TK-880 does not. Depending on the particular radio, RX will start at 442, or 443. TX goes a little lower. There's a simple VCO adjustment required to fix this.
I ordered a power cable since this one did not include cable or mic. The red and black leads on this supposed correct power cable are backwards! Darn good thing I noticed that before hooking it up to my power supply!!!
