I love my Alinco DR235; have it loaded up with milair/satcom freqs as it rx am/fm modes; great for listening to combat air patrol freqs. Receives up to about 289MHz.

Alinco's new tri-bander with DMR, GPS, and digital audio recorder.
50w on 2m, 45w on 70cm, and 5w on 220. Kinda pricey. But kinda interesting esp since I'm into DMR.

Looks just like the anytone 578 in a different case.

The front is not exactly the same. The function buttons are arranged differently. Alinco doesn't have Bluetooth. The mic is different. But who knows what's inside. The Anytone is Part 90 certified, which could be interesting to some people.
That’s why I said in a different case. Compare the two on features and they are exactly the same. I bet you could even put Bluetooth in it.

It might be interesting for someone to buy one of each and open up the cases. But I don't care that much.

I have an old Alinco DJ-280 HT that is 220 only. I can hit the few local 220 repeaters around here without much effort if I hook it up to one of my outside antennas.

I read over the thread quickly and I might have missed this but I haven't seen anyone talk about transverters. I wanted a real 220 radio and even an old one was overpriced. So I looked at the Q5 222 transverter and I bought it. Mine does about 45 watts he makes a higher power one. He set it up to use the 6 m band so that for whatever reason I might want to or need to I can use the entire band with. I've had it about 3 months and I hadn't actually used it yet. Built like a tank. I've got to drive about 400 miles to pick up an assembled antenna that I want to use and I hadn't done that yet have plans to do it soon. It's not cheap but neither is it an old radio and I'm going to use it with whatever radio has 6 m on it that I happen to own. I have a 220 repeater near me and people don't use it I can call out on it and usually get somebody to answer me back but you won't hear any talk on it. And I pick that up on a j-pole 220 and that's a vertical antenna and I really need a horizontal and that's the one that I'm going to pick up so that I'll be able to get get out as far as I can. But the one I'm using right now is the the 9000 I used it on the lowest wattage and I can cover 60 miles easily. A side note the tyt9000d has some hardware changes in the future they have a new board awaiting approval by the FCC. They did not say what changes they made. The current one is modifiable so you can build a repeater out of it.
So if you're really interested in having a radio the transverter is currently the only way you can do it and do it well. I believe that the flex radios actually have a facility to use a transverter for direct conversion. I'm also using ham radio deluxe and I believe that also will directly convert the signal for proper display.

When you say you can "cover 60 miles easily" on 220 MHz using the TYT-9000d, is this on simplex hill-topping or via your home base station? 60 miles is a stretch for any VHF/UHF band, barring a high elevation. Or are you referring to the talk-in range of that 220 repeater?

I was speaking of using the radio from my home to a repeater using my j-pole, using the radio's lowest power setting. I'm not in a valley might be up a little bit

The product description says mic does not need to be removed to do packet. I could not see any other port.
There is mention of use for a repeater and it also says it is not intended for 100% on and if it's used that way the power automatically drops to mid range.
This is unrelated with the exception of our imagination. About 3 months ago I was told by TYT they had a new 222 motherboard on the desk at the FCC awaiting approval. I could not pry the changes made to it out of them. I was whining about the lack of equipment.
If it's not a tyt I will buy it unless it's one of the new boards with some benefits. I own two of the tyt 222. Heck they don't really need any new designs just make some more of the tried and true models.

DollaRS TO donUTS, this radio will never see the light of day
I have no idea why you would say that. HRO had it available to buy on their website (even though out of stock). It wasn't even one of the "give us $25 and you can be first in line when this new radio is released" reservations. Do you think they just made this product up?
In any event, I got an email this morning that mine shipped. I'll make sure I post pictures of the empty box when I get it.

You should have taken my bet.
When you get it, I'd like to know if the control pins are exposed in the back. DB9 etc.

An inexpensive way to go just might be an ANYTONE 878UV.
I went to a workshop and the young man asked me if I would like him to program my 878. I said yes, as I could always write over it if needed. When I got home, I noticed that I could rcv/xmit on 220 MHz. Remarkable, since the owners manual does not offer any hint/endorsement/instructions for utilizing the 878 on 220 MHz.

If you plan on transmitting with that radio on 220mhz, it would be wise to put it on a spectrum scope and make sure the TX is within Part 97 specs. Those are SDR radios, and can be programmed very broadly, but it doesn't mean that it has the proper filtering for 220mhz. I can all but guarantee (because I own a 878+), that your radio does not have that proper filtering for 220mhz TX. You could find yourself in hot water for harmful interference.
The mean power of any spurious emission from a station transmitter or external RF power amplifier transmitting on a frequency between 30–225 MHz must be at least 60 dB below the mean power of the fundamental. For a transmitter having a mean power of 25 W or less, the mean power of any spurious emission supplied to the antenna transmission line must not exceed 25 µW and must be at least 40 dB below the mean power of the fundamental emission, but need not be reduced below the power of 10 µW. --97.305(e)

There's a reason for that...you can damage the radio. It's deaf on 220, barely puts out any power on 220, and like I said you can damage the radio.

My 878 is not deaf on 220 MHz. It transmits well enough to have me hit a 220 MHz repeater 35 miles south of my QTH, 4 X 5.
I've been checking into that net for more than 4 years; the 878 shows none of the maladies you have alluded to...
