Well, I've used Yaesu-990 for PacTOR (and AMTOR and you name it),
and on PacTOR the rig hardly got warm... Full power, 110W. Maybe
it was 980-specific problem?

[Setting Yaesu for PacTOR took me less than 1 minute, BTW! :-]

Subject: HF modem software on DSP sound card
To: [e-mail]

Hello fellow DSP experimentors,

After quite an effort, I now have a beta version ready for testing
my HF DSP modem software for a PC sound card. The sound card's DSP
runs the real-time modem code, while the host PC does bit-assembly
and the user interface. Presently only AMTOR is supported, but new
modes will be released in future.

Please note that this software will only work on PSA-based PC sound
cards, i.e. those using the Analog Devices PSA chipset that includes
an ADI 2115 DSP chip, i.e. Cardinal, Orchid... This is a minimal budget
alternative for a very useful DSP platform for PC's.

This is free software, available via anonymous ftp from:

UCSD.EDU /hamradio/packet/tcpip/incoming/psator.zip + psator.txt

Enjoy,

To: [e-mail]

I bought an older MFJ-1270 (Release 1.1.2 12/30/85) at a flea market thinking I
could use it with NOS.  After reading the manual it seems like there is no
command to put it in KISS mode.  Is there a combination of commands I can use
to put the TNC in KISS mode.

If this is not possible I wonder if the ROM can be upgraded?

Hello
       Does anybody know where I can get more info on the pa0hzp OPTOscc
card, or even better where I can get pcb's etc??.

Thanks in anticipation

Try ftp.funet.fi and the /pub/ham directory tree.

Subject: Permanent NOS Server
To: [e-mail]

Hi everybody,

I am an avid user of NOS in the local TCP/IP .ampr.org network, but I face a
tiny problem, so I decided to solicite some help from more experienced readers
of this list. Here we go :

I have a 80386/33MHz PC running NOS and a PK-232 connected to an Icom IC-229
transceiver. Now, this setup works OK, exept that the poor PC (hihi) has
developped a kind of fondness for the network and is always connected to it.
As a result, I do not have a PC for my other occupations (unfortunately I am
in computer business, so a PC has to be used in other cores also, except our
hobby).

I thought of using a dedicated PC for that, and I am currently looking for one
(OF COURSE for free, you don't pay for a PC in this business). However, I can
not ask my supplier (or should I say "my beneficiary") for an expensive, top
of the line machine. An 80386SX or DX with 1 MB of RAM and maybe a 40 MB disk,
is all I can look forward to. Perhaps, this will be enough for plain vanilla
operation, but I have also heard that you can use this PC as a server, and
connect my normal PC to it, as a client via a null-modem cable and SLIP
connection. That sounds like a very promising idea (remember : ignorance is
the source of happiness), however I am a bit confused over the whole setup.

Could some helpful soul give me some hints? Like for example :

1. Besides the fact that by following this setup, I can live with a lesser
machine, what other benefits will I have?

2. I presume that the two PCs will form a small network. Do I need an IP
address (from my coordinator) for the client as well as the one for the server
(I suppose that the IP address of my current PC will be given to the server
PC), or is the client IP address used only internally, therefore I should not
bother my IP coordinator?

3. What sort of client software can I use? I've heard that there are some
Windows-based client programs. Any hints please? Comments?

4. I initially thought of using network cards between the two PCs, but the
cost is high. Given that the radio is the bottleneck, how faster would it be,
if cards are used instead of SLIP connection?

5. Have I understand it correctly, that I could then add a modem to that
SLIP-using serial port and have access to my mail, when I am away from home
thru a notebook (using the same client software)?

Needless to say, that any advice will be greatly appreciated.

By the way, if my questions seem silly for the list, I wouldn't mind personal
answers at the addresses below (nor will I be offended).

Just to back up Drew's comment: on my path with W5XO (Porltand, OR to
central Texas - an excellent one hop path) we often observed the link
on 15M running at full 750 baud data rate for many hours at a time.
This is with low power (50W) and avarage antennas (tribander/dipole).
