The only thing I don't like about my Kenwood is that it's software interface is PC based. I had that when I bought the radio but I've long since switched over to Mac. So I can't program anything with my 71 currently. Not that I'd really know what I was doing anyway. But what about the dual transceiver part Ken was referring to? I can't find any details on that for the Kenwood. Only complaint I found during a search was the lack of "DTMF" what ever that is.
Most radio software is Windows (or even DOS for some radios we keep around) based. RT Systems is what a lot of people buy for Yaesu radios and it's Windows only.
The FTM radios can read and write to an SD card that I believe you can import directly from it into the radio. So presumably this file could be edited on a Mac with any spreadsheet.
Chirp software runs on macOS and covers most typical radios, Kenwood or otherwise. You do lose a few features and file types from the Kenwood software but it covers 99% of what you need to do I'd think. I think Chirp can even now directly read some types of Kenwood programming files but I have not tried that yet. Where Chirp usually lacks compared to OEM software is setting features or memory organization like using groups or scanning, which can sometimes be hard to reverse engineer by the volunteer who did it for Chirp. It just depends. But for straight up editing memories it's usually just fine.
Where Chirp really excels is that it's universal for most radios so you can use just one software and it can pull in frequencies from common sources like Repeater Book or Radio Reference if you subscribe to those. This is a
major benefit if you want to tailor your radio to a new location and want to get in the local repeaters with offsets and tones.
DTMF is Dual Tone Multi Frequency. It's what we old timers know as "touch tone" dialing. The TM-D710 can do DTMF. I don't really know what they're referring to. It's useful to access repeaters which sometimes require codes to control. The codes are a series of tones. It would sound like the string of tones you'd hear when you push the buttons on a telephone if you can imagine that. Pretty much all radios have been DTMF capable since the 1990s. It's usually a part of the microphone. It's what all those number buttons are there to do.
Dual transceiver means the radio can do receive and transmit on two frequencies at the same time. The TM-D710 does that, too. Although no radio can actually transmit on both exactly at the same time radios like the TM-D710, FTM-300, etc. can listen to two frequencies at the same time. They only have to pick a side to transmit on at a time and lock the other one out momentarily.
See how there's two frequencies? That's why that is. Now for most of us the second or B side is set to APRS frequency of 144.390 in the U.S. So that leaves the other side, primary or A usually, as the one we use to talk.
Your TM-D710 is in every way as good as a FTM-400, FTM-300, etc. with the exception of being able to do Yaesu System Fusion and it doesn't have the touch screen. It can do everything else on analog FM and APRS functions.
Just need the bracket to install the antenna
