Hey Josh, Just tried and succeeded in wirelessly connecting my new D75 to an ancient (think Windows 8.1) HP tablet with 2GB running Winlink. It was flawless. Thx for succinct instructions on the menu structure. It is also not lost on my spouse that I'm using an expensive HT to connect to a 2nd hand tablet from 10 years ago! My field runs & POTA will now be wireless thanks to Bluetooth & you.

My first email back in high school was over packet radio. TH-28 VHF w/ a kantronics TNC on 1200 baud. 9000 uhf baud backbone half way across the state to hit the internet. I had a TRS-80 (trash 80) with a 10 in floppy drive. Circa 1996

Nice radio, but for now I'll stick with my $30 BAOFENG and Digirig for my portable Winlink Packet. It works like a charm. Thanks for the video!

Until I can get an HT that is literally push email icon and connect to winlink app on phone or APRS button and connect to a APrS map, message app…. I’m not interested in these. I’ll mess with all this jank if it’s a jank radio.

I honestly don't understand how they make money on these ridiculously expensive handhelds. Even if you use something like my ft70d, you're only pushing 300, maybe 350 bucks for a full-fat APRS and winlink setup with a digirig and a cheap android phone. Or, just grab a raspberry pi, which plenty of folks have floating around, and you have a complete VHF/UHF packet radio setup, all for less than _half_ the cost of this radio. Like, it's nice that this radio has a tnc built in. It's nice that it has 222MHz. But it's not "spend an extra $400-500" nice.

@@b4ux1t3-tech do you really need this explained to you? Hobbie is full of retired white dudes, some of which have plenty of money. This radio is also attractive to a young tech buyers who come from the IPhone age where we don’t want a bunch of stuff cobbled together to send a text message. World is full of tons of people that are not like you. First radio that has a small screen with a map and AIS messaging like I can get on my motorcycle with nothing but an antenna, I’ll buy at any price. Something small. Doesn’t need to be 5 watts either for digital. A single cable off unit amp for mobile would be sweet. I can already do it with Mesh/lora and my phone….

@@Qwiv don't get me wrong, I know that there are folks with plenty of money in the hobby. But regardless of how much money you have, I don't see the value add here. Like you said, if it was literally "does the whole shebang in one package, applications included", I would actually say that's very worth the price of admission here. But... It doesn't. Haha. It takes the place of equipment that is _much_ cheaper. Not a little bit cheaper. _Half the price_ cheaper. That's what I mean.

Nice video on the updated radio and how you got the Packet stuff working!

"They sent a meme...thanks..." 🤣 I thank them for your reaction, it was priceless.

2:40 that’s actually me with ANY price radio. If I had a $700 radio I’d probably have it in a diamond coated bulletproof display box. As you would a 59’ Les Paul.

HRO has a couple of th-d75a’s left. I snagged one.

Thanks a bunch for this one. Ive been messing with my d74a with no success and i thought it was just my configuration, but it might be just the remote station isnt connecting well.

For what it's worth, the D75 battery life is slightly better than the 74 but you need to break it in. (charge to full, discharge to empty, rinse repeat) I've found that with my D75, I get 7-9 hours of APRS/Packet/D* a day.

Wonderful!

Followed this to a tee on my D75 but still no luck. When I click "Start" there is no transmitting happening on the radio. It's the correct COM port, no errors there. It shows bluetooth has connected on the D75. But no TX. Edit: Finally uninstalled both COM devices, reset the radio, uninstalled/reinstalled Winlink. Basically, I went nuclear and reset EVERYTHING. It finally started working. What a finicky setup. haha

First thing you do is put on a screen protecter. I have to say Kenwood menue is more intuative than Icom.

Hey Josh, thanks for this. I have the radio and love it (only 2m/70cm in JP), but battery drain is nuts. Carry a spare, for sure. Hopefully Kenwood can straighten it out and update via firmware update? Ganba 73 JQ7BJB

I use the Mobilinkd TNC4 for Winlink communication. I highly recommend it. Besides using the TNC4 with Windows, I can use it with RadioMail on iOS devices. The interface is identical to WinLink Windows. I would be interested if the Kenwood works with RadioMail on an iPad or iPhone.

Great video by the way

It may have already been said, but the symbol rate for 2M is 19.6 kilobaud. There are a number of reasons why 1200 baud has been traditionally used for 2M, but the FCC isn't one of them.

Both the D74 and D75 do KISS over Bluetooth, but I could never get the D74 to work with a cable due to some never-fixed firmware issue. Wonder if it was fixed in the D75.

If it's ever in stock anywhere, I'll grab one immediately and this vid will be useful. Money burning a hole in my pocket, they're on ebay for $1000, but I'm not paying that. So in the meantime, I ordered an Icom IC-9700. I need new toys, NOW.

SSTV over Winlink lol The battery on the D75 is 20mah larger than the D74, which really means that it is essentially the same. And battery life doesn't seem to have improved over the D74, sadly. I beaconed APRS for about an hour yesterday and it ran my battery down pretty quickly. After watching this, I think I will try to setup Winlink at the hotel in Orlando this weekend. It'll be fun to do it over RF with the Ed Fong antenna.

Battery life seems to improve significantly if you condition the battery by letting it drain to the point that the HT shuts itself off due to low battery, then recharging to full, about 5-6 times. After that, turning off all the bells and whistles while they’re not actively in use also helps. Bluetooth, excessive APRS beaconing, backlight timing seem to be the juice-thirsty culprits. Another thing to be aware of is that the battery remaining indicator might not be super accurate, and seems to go into the red quicker than it probably should. I believe that this has already been reported to Kenwood.

@@HamRadio2 yeah, regardless of the model, less power draw leads to longer battery life. :) Don Arnold has had his D75 a week or so longer than most of us, and has been (I believe) keeping track of the battery performance from fresh out of the box, and as he’s been conditioning the battery. He shared on a D75 FB group the information about the battery actually lasting longer after conditioning. I don’t have numbers, but I’m assuming he’ll share some with us at some point soon if he hasn’t already. For what it’s worth, my D75 battery (after conditioning) seems to be doing better than my D74 ever did. I’m testing with one band on D-STAR and the other beaconing every 5 minutes on APRS, but haven’t been keeping track of time before the battery dies. Might be interesting to start keeping track.

@AlGordon

As a quick follow-up to this: I caught Don on 30C this morning and got some numbers from him. He's getting around 8 hours after breaking the battery in, running APRS beaconing every 5 minutes at 5W, and the other VFO doing D-STAR or analog voice. Closer to 10 hours if he configures for less aggressive power draw.

Thanks for your reply to my Telnet comment. As you stated, the connection was made over WiFi and not the TH-D75. I discovered that having a problem pairing my TH-D75 on Bluetooth. I’ve tried connecting with two PCs, a laptop and a desktop, and in both cases the TH-D75 connects but does not pair. The PC drops the connection after about 3 seconds. I tried connecting using my wife’s Mac just to see if it would hold the connection and obtained the same result. Any ideas?

Can you get flat audio like you can on TH-F6A/F7E? For Vara FM WIDE or M17, or 4FSK AX.25 (supposedly you can push 19200bps 12.5kHz via Nino TNC and MMDVM in near future)

My Packet Channel Selector table came up empty. I discovered I had to hit the "Update Table Via Internet" to get it loaded. See timestamp ~14:30.

I’m looking to get either the Icom ID-52a or the Kenwood TH-D75a, which one would give the 👍 up!

We need a community-programmable, handheld SDR. For this huge amount of money, packet and only one digital speech mode ist not enough.

Is it well known that jankopotomus’s wall wart charges a th-75? Just tried it, seems to be. Charging away!

If you're asking the question, I'd say "no". Your D72 is full duplex. The D75 is not. It comes down to either a) there's features on the D75 you can't live without that the 72 doesn't have or b) you want the latest and greatest.
