I want 5 of these 900 radios when they come out.
I have been wishing for one ever since I got into this hobby!

As for HT cases, I have done some hobby casting of 2-part resins. I could probably make 1-2 pre-production castings for a handheld.

I like the Idea of a simple mobile, 12w would be plenty.
One thing I would ask for is heavy duty. I am in Public Safety, and I don't use standard ham radios any more because they don't "feel" as rugged asmy Icom F5061.

Also, Grounded mic hook to activate scan or a priority channel.

Also, need to have CTCSS and DCS Normal and Inverted.
Since there are not very many 900 repeaters around most of the US, A alpha-display with 12 charactor would be nice. 32 or 64 channels.

The TNC port on the back is a must!
Once these come out hams everywhere are going to want to build repeaters out of them.

I always thought alinco would come out with the first 900 ham radio.
We need to start using this band more before fcc takes it from us.
Did I say I will take 5 of them?!
Where do I sign.

If he wants to disassemble a 900 mhz device, his best bet
would be the 900 mhz wireless landline phones. It got everything he would need, in terms of parts (IC), etc. all he has to do is find a way to move the frequency to the ham band and increase the power output.

I hope that helps..
btw, let me know when he builds his 900 mhz radio. I want
2 of them :-)

Not having the ability to PC program them is a mistake.
900 is a very volatile band with new repeaters and frequency/PL/DPL changes occurring almost daily.

Alinco announces a 900 MHz portable at Hamvention:

Can a DR-935 mobile be far behind?

.........

He is worried that the production rigs might not get FCC approval, but I tried to reassure him that the FCC mostly would want to make sure the rigs don't leak RF or spurious signals... there don't seem to be enough 5kc deviation devices in that band for interference to be much of a problem in the first place.

...........

Would that it were that simple.  This is a fairly intense and costly process.

A better tack would be to offer a kit.  No need for FCC approval!

That would be GREAT!!  Or, maybe a "DR-29" or whatever?  Thank you Alinco!

I may be mistaken, and I really don't want to throw cold water on your plans, but I believe that if more than a single identical transmitter is built, it has to be submitted for FCC type approval.  At least that is the rule for HF band amps.

Other than that, I would also be interested in seeing a 900 mhz rig on the market!

If someone ever makes one, I'll take one too  Grin

Speaking of 33cm, and sorry I don't know more about this but maybe someone can comment: Are there any brands of 900 MHz cordless phones that share 33cm ham freq's? I thought I read an article about a guy using a phone in that band on the national calling frequency, that couldn't be correct right?
