I have a TM-V71A and like it. It' a real dual band radio and can 'do' both bands at the same time (two receivers). It has bells-n-whistles that are handy and some I've never even tried yet. The '71A is basically a TM-D710 without the TNC and a different styled control head. That control head can be left on the radio or remotely mounted. It is capable of 'doing' APRS but doesn't have it "built-in" like the '710 does. The same free software from Kenwood can control both radios.
How big/small is it? I don't have the measurements handy but they aren't hard to find. I have mine 'separated', the radio under a seat, the control head on the dash. Size isn't a problem. It's maybe slightly smaller than a common CB radio, but not a 'miniature' radio.
I like Kenwoods programming scheme. It seems logical to me, sort of arranged in 'layers' or 'steps'. Most of the controls on the control head have two functions. How long you hold that button in determines the function. And there's another button that changes the function labels. Not quite as much to remember, sort of.
What are some of my dislikes? There are two 'sides' to this radio and they can be set up for different bands or the same band on both. That's not a dislike, but remembering which 'side' I'm on, or not paying attention to which 'side' I'm on is aggravating at times. That's more my fault than the radios, just not paying enough attention. I wish that @#$ head had a 'sunshade' built onto it! It doesn't, so I just made one of my own. It keeps the sun/glare from making the screen so hard to read at times (dash mounted). If Kewood had asked me I could have made a much easier to use (but more expensive) mount for that control head. That's another 'personal' thingy, the supplied mount does work.
Poeple complain about the Mic not being connected to the control head but to the radio's body. That's a 'plus' for me. I can put that control head almost anywhere that I can run one cable. How about behind the sun visor, for instance, with no mic handing in my face. The mic cable is the same as a telephone's cable so making an extension is about as easy as the nearest Wal-Mart. (Kenwood is 'proud' of their cables, you know?)
Oh well, ain't nothing perfect (except me, naturally).
Best advice is to get your hands on one before buying, see how you like it.
(Oh yeah, it has a green or orange/amber screen. I like the green.)
I've been using mine for several months now and really like it. It has features that I have not used (like the remote control with your HT thing...) I don't use cross band repeat yet, mostly talk on our 440 repeater to some of the local guys. Once in a while I get on the two meter repeater. I have to remember to turn the volume down on the one I'm not using though, or it gets kinda confusing. :blink: The transmit audio on it is LOUD, even on the medium setting. I need to turn it down to low. Most of the guys around here use the Yaesu FT-8800, so it was kind of cool to have something new and different from the rest of the crowd.
Press F(unction) then Low, it'll enable "Mute", which turns down the volume on the non-PTT selected channel when there is a transmission coming in on both side. Your PTT selected channel takes priority over the non-PTT one.
