Dave,
Like you say, it is the chicken and egg situation, and that goes for
most of us because there are few places that have other users. You have
to get a nucleus of promoters in your area who can explain to other hams
all the benefits of why they would want to go to a new technology.

Hi Zack,
I have asked this question too and recently took a chance with a Black
and Decker MAXX SST series power inverter. They have several different
sizes and my daughter wanted one for her laptop in her car and found a
deal on the internet under $20 each, if you buy two and with no shipping
Practically speaking, there were two issues that the Winlink 2000 owners
tried to address:
1) Have a workable sound card mode. SCAMP = Sound Card Amateur Messaging

2) Have busy detection built in.
There was no time as a beta tester that I did not have the busy signal
detection. The

One of the QSO's was with a member of this list K2MO.
In fact it's been weeks since my WinLink system has
been used. Everything has been KB2KB.

Hi Rud;
Had similar problems with a Sony laptop when I was setting it up for
Echolink and digital modes.
Open up the volume controls on the computer and see what I muted and what is
open, and adjust the levels
as well. If you mute the microphone input and just use the .wav input , it
Remember, this was a couple of years ago. Plus, it really doesn't
matter if it is kb2kb interfering with a pmbo session or two pmbo
sessions. There was obviously no busy detection nor did the
interfering operators listen first. It was still pactor on pactor
interference and that is the point.
Hi John,
I did enough testing with snapping fingers to convince myself the internal
mike is shut off when the external input is connected. g Also, when it
does work I can see some signals in the waterfall and they move if I tune
the rig. I know wish I had tested this last week because I might

Hello Rud,
have you tested in software adjustment (menu Mixer in the Configuration window)?
If you don't success, let me a message ([EMAIL PROTECTED]) , we will see what

From what the Winlink 2000 owners have said in the past, they want to
control at least two frequencies per band in order to maximize access to
their scanning automatic stations.
There is no question that they consider the Winlink 2000 system to be
much more important than contacts between two
The negatives of D-Star seem to me:
1) It has lower audio quality than FM voice, especially for average to
strong signals. This is very disappointing to me.
2) The design to cripple the text data portion on the 2 meter/440 bands
is most unfortunate. They would have been much better off to

If PSKMail existed back then, I wasn't aware of it. It was not our
goal to replace Winlink, but rather to provide it with a better
transport protocol that could use PC-hosted soundcards instead of
hardware TNCs and would not QRM other stations.
So why do we not have such a thing today?
Not really Andy.
Pactor is a LSB mode whereas 65A is a USB mode.
with 1kc between the two. Should not bother each other.

How do I change from a real signal to quadrature? I know I have read how to
do this but cannot find a reference that goes beyond multiplying by cos/sin
to get I/Q.
I seem to recall a trick with alternating sign sequence of 1's. I actually
implemented the cos/sin technique but get 0s in

I've seen you mention these negatives about D-STAR several times on various
lists so I've felt compelled to respond.
I grew up in a rural area of Wisconsin similar to where you live. In a low
density area of population is difficult to support many things out of the
mainstream
How do I change from a real signal to quadrature?
Look into gMFSK sources, search for Hilbert transformation.
Basically, one filters the input signal through two low pass filters,
one results in real, the other in imaginatory component.
Also, do I remember that after the conversion the

I think that you have more of a seller's interest in D-Star and I have a
buyers interest. You spend a great deal of time promoting D-Star and
wanting other hams to adopt this protocol and even doing presentations
to a number of groups. Which is of course your prerogative and interest.

You may be thinking of mixing the real signal with cosine and sine signals at
1/4 the sampling rate. The sequence can be +1, 0, -1, 0 and 0, +1, 0, -1 for
cosine and sine or +1, +1, -1, -1 and +1, -1, -1, +1. In the first case,
computation can be minimized if the next stage is a FIR filter as
The testing that was done on DRM showed that the worst multipath spread is on
NVIS paths and is about 8 ms. They originally could accomodate only about 5 ms
