Just got this beast in today.
Initial impressions - One helluva scanner.
My unit appears to be defective in that it turns itself off and on seemingly
radomly.
Would much rather have a mechanical on/off switch than the little push button
thing.
Is a beast to program - Spent an hour or so just figuring out how to enter a
single freq, and though I have it set in English mode, alot of the menu and
LCD display are still in Jap.
Yes, it is the full functioned Jap version.
It appears it will be a major project to program 100's of freqs.

Haven't had a chance to try the flash tune, but the freq counter was
registering all my various wireless devices, though it didn't register my
cell phone or cordless [suppose they are a bit out of its range].
One major turnoff is its mega annoying noisy squelch tail - A shocking
ommision in a receiver of this class.
Otherwise, the audio sounds great and is quite loud, though once again it
takes a bit of work even to turn up/down the volume or squelch, requiring
both hands to do.

Was wondering if anyone suceeded in making a serial port/2.5 mini patch cable
to enable it to be programmed via computer.
I dl'ed the software, and it looks pretty damn good.
I can see where this will be a major headache saver, and will plop down
another $40 to get this cable if I can't make one myself.
My old digital camera uses a cable that connects to the serial port, and
terminates in a 2.5, just like the 2000 needs, but it didn't work.
I suppose Alinco made some kind of proprietary pinout scheme to force people
to pay a ridiculous price to buy their 'special' cable.
