If you don't get any other offers, I'm only about 10 or 12 miles from the
975-footer in Aurora, Illinois that took down an Air Angels chopper during a
night flight last year, killing the crew and the 13-month old infant they
were transporting. I could probably buzz out there over the weekend an

Hey
If you want a simple kit the partical Basic controller kit is very
reasonable.

Charles,
You can't "convert" a 28 VDC Astron power supply to a lower voltage, unless
you replace the power transformer and regulator board, and possibly the pass
transistors. Since the Astron linear power supplies use a series-pass
regulator design, the pass transistors could burn up if expected

Hi Fred,
It would probably be more accurate to call it a cross band

audio and COS/COR working together.

Ted , Have You checked with http://www.brinkleyelectronics.com/
I think You have know them for Years , If they Don't I am sure they will
know someone
Good Luck

Thanks Skipp...I was thinking there was more info on changing the base
station to a repeater and as Oliver said "Sir, I want more !".

Checkout the Astron page on the repeater builder website. There is a lot
of info on general linear supplies using the LM723 regulator chip.
You should be able to change the zener reference diode, and tune it down
to 13.8v and deliver the same current.

There ought to be an analog mode...if there isn't, Icom made a HUGE fubar!

Got to lay off the brandy so early in the morning... :-)

Skipp, where on the /sonic page is the MSR2000 info? I know I had a couple

gentlemen:
I hope all are recovered from the Dayton experience and dried out by this time.
my feet are still damp but, its a price i pay for schmoozing with all the folks
I saw at Dayton.
To the business at hand:
I searched all over but no one knew about this particular radio.
I have 2 vhf Maxon
At this point if you need to use the amplifier your best bet is to just
reduce the output until the desense goes away and call it good.

How about this - record a clean D-Star transmission (not decoded, just the
"raw" output from an FM receiver) on a PC with a good
This brings up the question of how one actually does testing of a D-Star

actually get measured. Having read that the D-Star boxes Icom sells are

To complete an MSR2000 and provided you have the correct modules for a
