My recent experiences with the MFJ-1274 haven't been real fun.  I hope
someone can point me in the right direction.  

First, i purchased the 2400 baud modem kit from MFJ and installed it according to
the directions.  This 1274 is fairly old, but it seemed to go in without a hitch.
I fired it up and tested it on 1200.  It worked fine. I switched to 2400 and 
started to monitor the local dx cluster.  About the only thing on 2400 around here.

Nothing.  I turned the trace mode on and watched gibberish come accross the screen.
Obviously, it is hearing something, but not what is being sent.  There are no 
testing instructions in the manual that came with the modem.  I went back to
1200 and it still works fine.  Any ideas?   I am still trying to find someone with
a 1270/1274 locally that has the 2400 in it working so I can slip mine in
and see if it is my installation or the modem.


2nd problem.  I purchased 1.1.8a from tapr recently.  I decided that maybe
my 2400 baud problem might be related to the 1.1.4 version of the software that
I was running, so I put the new ROM in.  Well, it gets as far as lighting up the
leds that are normally light up for a brief period after the power is turned on.
They never go out and I never get a response on the com port.  

My questions are:  
Do I kneed 1.1.8a or at least something more than 1.1.4 to run 2400 baud?
Do I need to do something to the 1274 to be able to use the 1.1.8a software?
Will the tapr chip work in the 1274?  I told the nice lady what I intended to
put it in when I ordered it.  If it wouldn't work, I would have thought that
she might have know or maybe that was a poor assumption.

I am a fairly compentent technician, having built lots of things, both from 
scratch and from kits, including lots of computer related stuff.  I know how
to put chips into sockets and get them out without bending the pins too much. 8^)
I even used a esd strap and bracelet when installing the ROM, but not the 2400
baud modem. 

So, in a nutshell, do I have two independent problems? Is it all my fault for not
consulting the stars before starting?  etc.

Thanks for any help.
Please reply by email, since this isn't something I would guess is very interesting
to the rest of the earth.  If anyone is interesed in the answers, drop me a note and
I'll forward the results to them.


Jim.

I'm working through the logic to tie a TNC directly into our full-duplex
19.2kB packet repeater.

It's pretty straightforward; DCD from the repeater receiver drives the
TNC to prevent TNC data from mixing with repeated data, and vice versa
to keep received data from grunging the TNC when it talks.

But beyond that, has anyone come up with additional logic to improve
performance?  e.g., is it worth using latches to give one data source
priority over the other?  Are there race conditions to watch for?

Any insight from those who've done this already would be appreciated...

Subject: Problems with Icom IC-245 & Packet
Summary: Help wanted
Organization: Abacus Computers - You Can Count On Us
Date: Mon, 4 Jan 1993 15:22:24 GMT


OK, I'm having some trouble connecting my Icom IC-245 to my new TNC.  Here
are the details:

Equipment:	AEA PK-88, IBM Clone, Icom IC245 

Now, first off, the PK-88 and computer work fine.  In fact, connecting them
to my Radio SHack 2m HT works flawlessly.  However, when using the
Icom.....

Well, I have it wired correctly and I can connect to a local to me
digipeater.  However, it is very unreliable to connect to anything else.
According to some locals who have monitored my transmissions, my
transmitted packets look fine and the other stations are sending back
packets, however, I don't receive them.  

Yes, I do receive them, but on the PK-88, I get "Frame too short" errors.
My PK-88 will try 10 times to connect, 10 times to other station will
respond, my TNC receives but does not decode it, I get a "Frame to Short"
error most of the time.

Now, If I wire the PK88 to xmit through the Icom, but receive via a scanner
I have, all works well.  Also, all works well with the one digipeater here
in town.  However, any other system does not work and I can seldom connect
to them, and even when I do, I almost immediately get a "Disconnected: Time
out, Retry limit exceeded" errors.

So, it seems something about the Icom's receive section does not work well
with packet.  Two theories have emerged among my local packet elmers:

1.	The Icom 245 tx/rx relay is slow and after sending a "COnnect"
packet, it can't get back in receive mode fast enough to hear the response.
Possible the local digipeater has a delay set on it such that it keys the
carrier, and waits a few milliseconds, and then sends out packets...
perhaps even long for my Icom to switch to receive mode.

2.	The Icom 245 Squelch is too tight/loose and does not release the
squelch fast enough to get the first part of the packet through.  Agin,
fits with the digipeater working and not others.

To test these ideas, tonight I will try monitoring the packet channel with
the squelch off.  If I see all the packets properly, then it looks like it
will be 1.  If however, on just monitoring, I get packets incorrect, it may
be two or some other problems.

Does anyone have any suggestions, help, or advise they can offer?  How
about anyone using an IC-245 on packet?

FEC has several advantages.

First is power gain.  4 to 7 dB of FEC gain against thermal ("white")
is typical, depending on the specific coding technique and
implementation chosen and the amount of excess bandwidth available.
Against *non* thermal noise (particularly impulse noise, such as
radars) and when combined with interleaving, FEC gains can be stunning
-- many tens of dB are not uncommon!

These gains are just as though you had added a power amplifier to the
transmitter, put up bigger antennas, or improved your receiver's noise
figure. But it comes from "brains" rather than "brawn".

The second (and related) advantage of FEC is greater resistance to
interference. Interference is really just artificial noise, and since
FEC allows you to operate with a lower signal-to-noise ratio, you can
tolerate more interference from others who share the frequency.  And
because you don't need as much power yourself, you cause less
interference to others. This means you can pack co-channel users
closer together, and this more than makes up for the extra bandwidth
needed by the FEC itself.

This is especially important in spread spectrum, where interference is
the limiting factor in network capacity.

Hi again folks,

Re:  problems wiring up the cable betw my kpc3 and my Yaesu ft-411 ..

After a lot of noodling around and finger-burning and cussing :),  I got it
working.  Mike kb2kyz suggested that I try a lower val resistor (470 ohms).
That, combined with using the *little* submini plug for the PTT stuff
(yes, the book's picture _is_ deceiving!!  grrr..) did the trick.

I'm just concerned that maybe 470ohms is too low, and too much current in
either the tnc or ht might sizzle something..  I'll have to consult the specs
sheets to see if there's some 'max sinkable current' listed somewhere...

Thanks to all who volunteered their help!

You are the grand prize winner!  After checking the pin out of the plug 
on the KPC-3
against my radio (a Yaesu HT), I discovered the the diagram showed the plugs
exactly backwards.  I was so mad I showed my wife (like she cared) and 
asked her
what she thought the diagram was showing.  After losing one set of 
plugs (it wasn't
worth desoldering), I was on the air.  That is the only problem I've 
seen so far however.
I love the unit although that is an extremely frustrating first experience.

My unit was not configured for HT.  If you have a screwdriver handy (as 
opposed to the
manual) you can verify this because the jumper is actually labeled 
"HT".  I debated using
this myself but I switch it between a mobile and an HT.  Changing the 
jumper each time is
more difficult than just building that stuff into the DB-9 hood (just 
keep the leads short).

My own question is how to make a cable for an Alinco DJ-580T.  It has 
that weird stereo
submini mike plug and I can't find a pin out for this guy anywhere.  I 
have heard there's
actually power in that jack however, so I'm not going to experiment.

    I am interested in getting involved in high speed packet and I have a 
number of questions. I would also appreciate any information about experiences
with high speed packet. I don't have an amateur license but I plan to get one in 
the new year. 
 
Can the Kantronics D4-10 data radio support speeds faster than 19200 baud
 (standard speed) through its built in TTL port and data slicer?
 
Is direct connection to the D4-10's TTL interface compatible with Kantronics
19200 baud modem card? (data scrambling???)
What is the current street price of the D4 radio?
Is there a quantity discount?
 
What kind of modem is the Grapes 56k baud radio modem and what are its
requirements for use?
 
Has multiple frequency shift keying been employed on the amateur bands?
******************************
   I know that the Kantronics 9600 baud modem card also supports 19200 baud,
with both analog and TTL inputs and outputs. One could use that modem for 
19200 receive on its analog inputs with a simple wideband FM receiver chip. 
You could then employ what ever transmit capability you could muster up 
(1200/2400/9600) for communication to your local tcp/ip server. The server 
would have a local 19.2k baud user port and a 9600 baud network port. 
1200/2400 baud would have to  gateway into the server.  My question: is there
 anybody that has or is planing to write software that allows high speed/lowspeed 
packet and packet acknowledgments over different speed nets? This would seem 
to be an important capability which would allow high capacity use of the server 
computer  (interactive telnet and FTP)  without bringing the regular packet network
to its knees. With the development of fast digital modulation schemes in excess of
 64k baud the amateur service could provide fast,reliable and cheap 
communications services to individuals without ISDN or dialup slip lines.

This is a real 1200/2400 bps that is RELIABLE.  It is not retry several

I read the FAQ, but I don't understand the distinction between a TNC, a packet
radio modem, and a radio used for packet radio.  Is a TNC the same thing as
a packet radio modem? (I've used phone line modems since 1981, so I pretty 
well understand what a modem is, but don't understand what a Terminal Node
Controller does.) 
What I am mainly trying to figure out is this:  What type of setup will
allow high speed operation  >= 9600 baud?   What bands are used by high-speed
packet radio?  How many people (approx.) operate at these speeds?  What
are the limitations?

According to my TCP/IP manual it stands for:
Serial Line Internet Protocol

It is (as the name implies) a method whereby a user can connect
to a given system via a modem/asychronous line and use the
system interconnections (network commands) as if you were
actually connected to the LAN. Needless to say, it is slower
than the equivalent hardware LAN connection, but is a _very_
handy way to access the power and resources of the net.remote.
