Hi Andy and list members,

Yes, there was a major post this morning on here with links to two new
products. I was rather expecting some comments on it, especially since what
they are doing is providing a "system" that allows a server stations to
permit a client station to access directly into the internet via HF.
Including web browsing. I do not support this on heavily used HF
frequencies, but maybe it could be used on some unusued frequencies such as
daytime 160/80 meters.

This concept sound similar to the capabilities of JNOS2 with its new HF
connections via the SCS modem and other modems. Anyone else here know any
more details or figure out some kind of comparison.

The thing that I do like about it is that it appears to eliminate the
achilles heel of the Winlink 2000 system in that you avoid having several
additional layers of servers between the client to another client or even
the internet. With Winlink 2000, if they go down, the entire system goes
down world wide which makes it too fragile, in my view, as the ultimate
emergency solution. I am not suggesting that Winlink 2000 has no value,
because it can be used to jump over a failed area of the internet. The
assumption being that the internet (and Winlink) will always be operational.
So you need to insure a fall back system if you want serious emergency
communication.

Rick Muething, KN6KB could have put a keyboard mode into SCAMP but
specifically has said he will not do this. I believe his  reason is that
since it is a wide band mode it should not be used for casual keyboard use.
My hope is that after they release the mode into the GPL, others may be able
to develop it further.

Any particular reason you don't operate MFSK16 a lot? I consistently find it
better than most modes. Especiall for such a narrow mode compared to the
wider versions of MT-63 and Olivia. Which modes do you find work best for
you? Especially for lower band QRN at night?

73,

Rick, KV9U

Thanks for  the test Rick .  Did  SCS announce something new at
Friedrichshafen ?

I agree that Scamp needs a keyboard component.  I am not sure about MFSK16,
its been a couple of years since I experimented with it .

By the way, after you faded.. V73AX popped up , CQing !

The band sure dropped out. You signal was around 589 or so and after sending
the message, my machine must have tried to check with you to see if you got
it and since it did not get anything back, it resent the data a second time.
If you note, under the program preferences, the "frame size" is 150 so that
is fairly large for a text type of message. Maybe we could try this again
some time and use a shorter frame, say, 50?

I wonder if it then would pause and check for receipt of that frame and
resend or time out if it does not go through? Although it only sent the
message twice, it appears to try 3 times then to see if there is a further
chance for data flow. Since it could not hear anything more it then did
indicate in the status box that the message "failed" so it did not know that
you had received it.

While the system is somewhat crude by today's standards, it seems like a
useful program. I had a short Q with N3IJ shortly thereafter but he faded
out. He was using only 2 watts though and was extremely weak initially and
right in the noise but still printing 90% or so.

I did find that the program prevents proper operation of my GUI interface
for the TenTec Pegasus here. I must boot the Peg first and then the FNPSK
program or else it either won't allow it to connect properly, or if it does,
it causes odd behavior such as uncontrolled VFO movements.

I wish we had something more like SCAMP which is really slick the way it
connects and does everything for you, but does not allow for keyboarding.
And SCAMP needs a much better protocol for the typical weak signals similar
to what we experienced tonight. I wonder if MFSK16 would have been any
better? It would seem that that is a mode that could be used as an
alternative to the PSK modes for very difficult conditions as long as you
did not have severe polar flutter or similar doppler that messes up slow
baud rate modes. Everything is a trade off, isn't it:)

There are days that I almost succumb to buying one of the SCS modems since
there is such good support for Pactor I, II, and III with everything from
Winlink, to the NTS system, to now even JNOS2 and then the latest thing that
SCS announced today. But then again.....

73,

Rick, KV9U

Rick and I did have success!


Here is what I received

NUM:  1 PREC:= HXG:= STATION ORIG: KV9U  CHK: = 12 PLCE ORIG:= VIROQUA WI
TIME FILED: 2349Z CDT  DATE: 22 Jun 2005
TO:= K3UK
TELEPHONE:=
MESSAGE TEXT:= HI ANDREW X HOPE YOU ARE ABLE TO COPY THIS MESSAGE OK
SIGNATURE:= RICK KV9U


Band faded so I am not sure if Rick received an ACK.

This has promise.
