How much stuff comes active from the factory?

I don't recall off the top of my head, but GPS was definitely active on the one I got, and it will eat batteries. Pretty sure Bluetooth (another battery hog) was active also. Deactivating those two alone will save you quite a bit of juice.

Beware of dual watch also. While not quite the battery hog that GPS and BT are, it does use more battery since the RX is active more frequently.

Sounds good. Does D-Star compared to analog use more battery?

DStar should use same amount of battery.

There is probably a slight overhead on the vocoder, but not much.

I'm pretty sure APRS is off by default, that needs a bit of setup before activating.

Battery life hasn't been an issue for me. This was the HT I carried for 3 days at Hamvention last year. Charged each night.

On the screen scratching, go on EBAY to BestSkinsEver. Bought their protectors for my D74 and my SDS100. Both still have the first one I installed. Those things are tough. And FWIW, I'm a field mechanic, so my portables are getting dust blown and even misted on when the weather is rough.

I will look into a screen protector

I took my HT apart, it has a huge metal chassis. The antenna connector is firmly attached to the chassis.
Yes, but the SMA center-conductor fingers are still very fragile. As you probably know, if you aren't careful enough attaching SMA connectors, you can damage the fingers. And should you damage the BNC end of an SMA-BNC adaptor, you can get a new one without sending the radio to Kenwood.
Back when I was doing sustaining engineering, we found data indicating that SMA-Female center fingers were not intended for a large number of mate-demate cycles. Metal fatigue, I guess.

I think your memory serves you well. As recall SMA has a relatively low cycle life. Your BNC advice is sound. I just wanted to rely what I saw within the case.

I think it would be trivial for radio tech to replace the antenna sma on this HT.

I have a near endless supply of SMA connectors at the radio shop I intern at.

I've found that any digital mode will eat more battery than analog, simply because of the additional circuitry and processing involved. YMMV depending on your settings.

Regarding Tom's comment about memories...

The TH-D74 has 1000 memory channels. Each channel can be assigned to one of 30 groups. You can then scan just the channels in a group. The groups can be named. You can also link groups together and then scan the linked groups.

I don't use it. Interesting "gee-whiz" feature, but not all that important to me.

I use it occasionally. It's handy when I'm out gallivanting about and feel like listening to the few English SW broadcasts are out there (or if I need to monitor WWV to check the time to verify the computer clock).

I've had mine since shortly after Kenwood introduced the D74. I upgraded from the TH-D72. I'm pleased with it.

I use all the functions, APRS, D-Star and 220 mHz. I have a dual band linear amp in the car. 40W on 2m and 30W on 70cm (but no 220). I connect the radio to the amp throw it on the console and use it as a full mobile.

I use the Bluetooth feature a lot while mobile with a BlueParrot B250XT headset. VXi BlueParrott B250-XT Bluetooth Headset - Walmart.com -- I wired up a foot switch for the PTT and put it on the floor to the left of the brake pedal so I can be fully hands free while driving.

If you have a computer with Bluetooth, you can pair it with the radio and then program it without the need for any cords.. (Although it's incredibly slow compared to using the USB cord). My car stereo has Bluetooth, but I've never managed to pair it with the radio. It would have been nice to use the car stereo speakers to listen to the radio.

It's not bad at all on HF. The internal ferrite loop antenna doesn't work that well. (Even for local AM broadcast stations). But when connected to my tower-mounted 3 element HF Yagi it really shines. Not only do AM shortwave stations come in clear, but it picks up SSB and CW stations equally well. Plus, they're easy to tune. (I don't use the D74 much for HF since I have a dedicated radio for the purpose).

The downsides.... As others have mentioned... It is a bit pricey. Plus the color display can be hard to read at times with the backlight turned off.

There's a black and white screen mode that I saw in the manual.

There is no black-and-white screen mode that I know of. Your choices are a black background or a white background. With either one, the colors are still there.

Yeah the white background is what I was trying to say. The numbers and letters are black and the background is white. The icons are in color.

Just bought one w/ the $50 off Kenwood discount & an additional $20 off retailer discount going on ($480 + tax). So far quite impressed & more than happy with the purchase, relatively speaking though... It's expensive for what it is, there's no denying this; however, it's a super niche luxury item that requires a high margin to be profitable / worth the effort in the market.

My biggest complaints are the super touchy buttons that are easily pressed accidentally by simply picking up the radio if not careful, the poor screen utilization where more info could have easily been fit in when A&B bands are both enabled, and the BS low amperage charger that's included which is reported to be potentially damaging to the radio if you transmit while it's connected.... Price of accessories are also stupidly expensive as well for what they are, but that's kind of par for Amateur Radio... If you're going to use this radio a lot, I'd pony up the extra $25 for RT system's software, as it would have taken countless frustrating hours, over several days, w/ a lot of mistakes to program the 700+ channels & 23 groupings I wanted with the Kenwood software...

Other than that, no major gripes. Learning curve is a little cumbersome at 1st w/ a few annoying bits about how they designed the user interface, but really not a big deal in my opinion. I'm an electronics engineer, so I guess that probably helps a bit ;)

The receiver's front end deals with the massive AM & FM broadcast station that's 1/2 mile away without noticeable issue. Deals with the ridiculously powerful police dispatch VHF transmissions without apparent issues. Both of these sources of noise overload the front end of most of my other radios, even with auxiliary Par electronics filters on the receive antenna cables.

Scanning speed is definitely the fastest I've seen in any amateur radio transceiver I've owned. Definitely not as fast as a modern scanner radio from Whistler or Uniden, but more than fast enough for legitimate use as a scanner radio, so long as you break things down into groups that make sense.

Audio quality is very useable, definitely a several notches up compared to any other HT or portable radio I've owned. The EQ function for both Tx & Rx is definitely a worthwhile option that I've always used & liked on my base station transceivers (especially when connecting to auxiliary speakers).

It's a bit bulky compared to other HT's, but it's far less bulky than any of my scanner radios. The TH-D74A will be replacing 3+ pieces of gear, and a whole lot of hassle, when overlanding out in BFE where there's no cell signal and where I often don't know exactly where I'll end up or go over the following week (which scares my family)... APRS for location tracking, VHF for communications, & general HF / SW listening to whatever, all done with this radio alone, w/ an Icom 5100 mobile & a legit mobile antenna on the car's roof serving as a crossband repeater at basecamp.

The only other gripe I have is the Bluetooth function is not well implemented for audio pairing. With the capable & competent receiver in this radio (compared to just about any other portable receiver I've used), Kenwood should have enabled a "speaker" profile. I've not had luck connecting the D74 to bluetooth speakers so far. Would really be nice to connect this thing via bluetooth to any bluetooth speaker I want.

I'm more of a listener than a talker, but I've been talking a lot more with this HT to see just how "bad" the battery life is to se if it's a deal breaker for taking up North... I'm not impressed, but I'm also not disappointed in the least... With my attempt at "heavy" use, which is likely pretty light for a lot of folks, a fully charged battery lasts a solid 2+ days.

So your saying I should just get an ID51 for much cheaper?
