Hi,
Do you know where to find the MC13055? According to Motorola in Sweden,
they don't make it anymore, but I hope to find it somewhere :-)! I'm
planning to use the IC in the ARRL Handbook 2Mbit datalink, and if
I can't find it, I'd like to get info from people who have replaced
it with some other. MC3356? MC13155? NE604? NE605?

Subject: [Q]: FBB(5.15)+BPQ(HF&VHF)+modem. Modem does not answer...
To: ham-digital@ucsd.edu
Hello and thanks for reading this posting.
We are having trouble with FBB(5.15) + BPQ(HF&VHF) + modem. Modem does not
work properly in answer mode (it does not answer incoming calls) but it works
in originated mode. Modem is internal 2400 and works very good with other
terminal programs (Telemate 3.10). The computer is IBM PC-AT (10 MHz).
If you can help us, please send an email to me. I'd love to hear from
you!
MANY thanks, in advance.

Subject: a scary idea for the DEC Rainbow
To: ham-digital@ucsd.edu
Maybe I'm missing something obvious, but why not just kermit into
a unix host and use the DEC box as a dumb term? For SLIP to be useful,
you would really want a multitasking OS, wouldn't you? Unless you
made a SLIP TSR thing just to run a telnet or ftp daemon (although you'd
still need a multitasking OS if more than one person wanted to log in)...
sounds like an interesting hack though, if just for the sake of a hack,
but I thought hacks were supposed to be insant *looking* solutions to *real*
problems...

I'd say "rather aggressive" is mild (:>). Not only is there bad
spreading but (assuming your attenuation numbers are correct) your
receiver gets to see +40+33-280+33=-174 dBm. Since the moon itself is
about 200 Kelvin at 10 GHz (though with only a 33 dB gain antenna it
will not fill your aperture) and if the receiver has a 1 dB NF you get
about 0 dB C/N in 1 Hz of bandwidth. Shannon has to be reckoned with
and I'm afraid you are now about 7 orders of magnitude away from a goal
of 10 Mbps.
I think you'd stand a better chance with a series of troposcatter links
across the path.

Hi Dennis, There is no such thing as a registration for GP.
It is a very versatile and comfortable software, and it is *FREE*,

About the english version, may be writing a line to Ulf, the autor

John..
It is like the KPC-4 only built in a slightly larger case than the KPC-3.
It has two modems 1200 baud and 9600 baud. You can operate both at the
same time and it does have the ability to operate as a KANODE with
cross-banding. I have had mine for about a month operating 1200 baud on
two meters and 9600 baud on 440. I am using it with KAGOLD software.
I am very happy with the performance. I would recommend considering
the 128K memory (approx $25 US) option if you need a large mailbox or
several NUMNODES.
73,
Bob

>>I don't recall RSX being particularly derived or inspired from CPM...
Sad how history can get rewritten by someone who thinks their
favorite OS was the first one in the world, especially considering
1/ The obvious 10-year chronoclasm between the emergence of RSX-11
and the emergence of CPM, and
2/ because CPM was a TOTALLY OBVIOUS port of OS8/PS8 from the PDP8,
since the names, command syntax, etc were identical. (Come on,
PIP, TECO (with another name,) ...)
3/ if you look at the Intel and motorola chip dynasties, you find
8088/80286/etc were early implementations of PDP8 micros, and
CPM-DOS etc looked much like OS8.
Motororola 6xxx series were modeled more on the PDP11, including
the hardware for good multitasking.
Most of the monstrosities of Windows, etc on the PC result from
building on the wrong foundation, that of a single-user computer
and system.

I am considering the KPC-3 also, my only concern is that
1200 baud will be obsolete soon, but I am a packet newbie,
so I don't know if 9600 is prevalent here in the states.
Still, at $115 US, it is a low risk proposition.
9600 baud TNC's are about $225.
What is the net wisdom?

Just thought I would throw my two cents worth your way I owned a
MFJ-1270B which is the same as the 1274 without the tuning LED I switched
to the KPC for taking on the road for size and pwr reasons . I would say
that they are both excellent machines I had my MFJ for 4 yrs and it is
now digipeating on a Hill in PEI. Now the choice should be made based on
what you plan on doing with the tnc if you are only going to do VHF work
with it then then the KPC-3 is the way to go . If you plan on dabbling
in HF packet ax.25 protocol then get the MFJ . For the same price you
get one mode on HF . Hope this muddies the waters a little :-)

Greetings,
Would some kind soul please tell me how to get a copy of XPCOM?
My understanding is that this is a RTTY (possibly other modes) terminal
program that is highly regarded by some. I beleive it was written
by KF7XP.
If someone is aware of an FTP site where it can be found please let me know.
Otherwise, I'll try mailing a note to the callbook address for KF7XP.

I'd like to see the dx "coming" ie aas night falls DX should sweep toward

I thought the same. Is the slushware included in the OS/278 source?
I need to modify the serial printer port driver so that it goes bidirectional.
(The radio TNC will go on the printer port and the SLIP will go on the
comm port.)
Alternately, I've a serious need for a 6120 disassembler and disk editor.

Makes two of us; I can probably get KA9Q with BIOS calls, if I get it going
at all, but using the 6120 I/O would make things more efficient and perhaps
even more interesting (!) as well...
