Thanks Drew. I didn't make on L band last field day but will be set up

D-STAR radio needs not only the AMBE codec chip but also linear codec, GMSK
modem chip and control cpu. (see
http://d-star.dyndns.org/IC-2200H/IC-2200H052.jpg UT-115 is same as UT-118.)
So, I think D-STAR rig is over $100 higher than normal analog rig, (Analog
part of D-STAR rig is same as normal analog rig.)

I believe you are correct there, a rebadged ID-800, according to what
I've read.

Only the other manufacturers can answer that. The situation
certainly hasn't stopped ham experimentation, and there has been at
least one somewhat D-STAR capable radio built (there were issues, but
they were related to the specific components chosen). There is a
software based D-STAR demodulator
(http://groups.yahoo.com/group/dstarsoftware) that apparently works
quite well, when connected to a 9600 bps capable radio. Of course, a
DV Dongle is needed to recover the audio, but the software will
decode the headers and the low speed data stream. Transmit is just a
matter of the author getting around to writing that capability. At
this stage, he has been focusing on improving the receive performance
of his demodulator.

You have a point. The true single source issue is not ICOM, it is
really DVSI. We can fix the ICOM part ourselves over time, with DV
adapters and surplus FM radios with direct discriminator/modulator
access. The controller might be trickier, but not beyond our
capabilities, given time.

We are stuck with AMBE... for now. Perhaps in the future, there will
be a way to incorporate other (i.e. open source) vocoders alongside
AMBE. However, the developers will also need to push to get the
vocoder into silicon fairly rapidly, once it's performing acceptably,
so a manufacturer can produce the chips in the millions for
installation into radios. The ideal vocoder will have readily
available and unencombered software (for running on a PC) and
hardware (i.e. DSP chip for installing into a radio) implementations.

In an ideal world, yes. I believe we need to work with what's there
now, and at the same time push for a better future.
>Bruce echos most of these issues on his page:

Unfortunetely, he does get a few critical technical details wrong, if
he is interesting in writing a vocoder compatible with D-STAR. Such
a vocoder needs to (1) compress voice down to 2400 bps (not the
5000-6000bps he states for VHF), and (2) provide FEC, as the D-STAR
protocol itself doesn't provide FEC. The difference in bit rate
between 5000 and 2400 bps is a world of difference for
performance. Of course, we can always use LPC-10 and sound like Daleks... ;)

Actually, according to Dan Henderson, N1ND - ARRL Regulatory Information
Manager - Field Day Manager you are only allowed one QSO per FM satellite in
the ARRL rules.
I asked for and got an "official" clarification stating if you work L/U on
AO-51 then V/U would be a no-no, or vise versa. The quote was "You can have
only one QSO per satellite ..... Doesn't matter how many transponders,
etc."

remember... although arrl and amsat rules are similar, they are not
identical. for amsat field day, you may make one contact on each
single channel transponder. if both transponders are turned on for a
particular satellite on field day, you can make one contact on each.

Hi Colin,

Well, those prices seem high but I guess the recent price increase
pushed things up to compensate for the drop in the US dollar.
The 91AD was less than $350 at Dayton so your price seems too high. I
got a 92AD for $516 ... I just checked the price of the 91AD at HRO
and it is $434.95, so you need to shop elsewhere I guess.
But to be fair, you need to use the Universal site properly. The LIST
price for the 91AD is $524 - you need to push the button and see that
their price is $399.95 ... I don't want to start an argument here
but a big part of your argument surrounds cost and you are
presenting VERY inflated prices to back your argument.
I understand all of your other points but do not believe that these
are show-stoppers. If you are quoting Universal prices, you may live
near Columbus .... they apparently have a D-STAR system on down there
so you can check things out.

Hi,
There is what appears to be an updated version of 12.8 available. It is
still listed as 12.8, but the SETUP program is dated 9 Jun 08. After
backing everything up, I installed this version, and then restored my SQF
and other configuration files. The only issues I had noticed previously
were with the available maps, and SuM. Both are now working correctly, and
nothing new seems to be broken.
Note that unlike past upgrades, the installation program detected the
previous version and required me to uninstall it first. Perhaps the new
installer? So be certain to keep copies of the configuration files.

I have been following the pros and cons, plus the usual gripes,about the
recent bunch of cubesats with some interest.Thes are a few points that ought
to be taken into account:-
1) transmitted telemetry should be in a format that can be decoded,
understood and have meaning to the Amateur Radio community.
2) it should have a valid amateur radio call sign if its to be allocated a
frequency in the Satellite section of the Amateur Bands.This will make sure
that builders are aware of what Amateur Radio is all about and might even
encourage some to get a call sign.
3)all beacon frequencies should be kept clear of linear/single channel comsats
i.e. 437 and above and channelised to eliminate the Compass/Cute1.7 situation.
RS30 doesn't exactly fit into this stuation because it not a cube sat,but it
does fall foul of item 1and to some degree 3) as well)
I will now sit back and await the flood? of remarks positive or
negative!Regards Robert G8ATE
