X-BBS-Msg-Type: B
the newer afsk rtty scenario, mean the higher of two rf emissions? Why does
SCS
refer to the higher frequency rf Pactor emission as mark? Why do several
definitions I found for afsk identify the higher of the two generated rf
frequencies as mark?
Can someone refer me to some authoritive source that verifies or belies the
quoted "tune"? I am approaching a conclusion, possibly false, that I was lead
astray some years ago by an argument from authority. I realize that a
definition for a published rf data channel and a tty term may hold little in
common and I may be out of line relating the two, too closely.

Other than I will have, in fact, eschewed obfuscation! Surely there is
sufficient without me adding to it...

Subject: FT-2600 mic to TNC
Has anyone hooked up a Yaesu FT-2600 to a TNC through the mic connection ? I
am need of info on what wires to use from the connector.
The reason I was asking was that the manual ( Yaesu ) shows the following
pin-outs for the 2600 mic plug....
1 SW 1 (multi function switching)
2 Cloning
3 +9 V
4 Ground
5 Mic Input
6 SW 2 (multi function switching)
No PTT shown
So do I use the mic input and ground only ?
I am planning on using either a KPC-3+ and/or a BP-2M TNC.
I have heard that the data port on the back of some radios doesn't have
enough umph to work a TNC.....
thanks for any help you can provide.

You are welcome to connect to the internet accessible AR-Cluster at KC0DJO
in Duluth Minnesota.
The IP address is 209.32.226.63
At your first check in you will be asked for your Call, Name and QTH. Please
enter your QTH in the form: Chicago IL or Oslo Norway so that we will know
where all our new friends are from! You will also be reminded to
SET/LOCATION, that's optional but recommended. If you set your location,
then the AR-Cluster will calculate beam headings for you to various
prefixes. For HELP on these commands you may type
HELP SET/NAME
HELP SET/QTH
HELP SET/LOCATION
To see what you have entered type: SHOW/STATION your_call
You can correct any errors using the SET commands.
For more information on AR-Cluster including a Logon Tutorial and Command
List go to this website:
http://www.cestro.com/pcluster/index.shtml
Ideally you should use your logging program to make your telnet connection.
Its a huge advantage as then your logging program will monitor the dx spots
and alert you to contacts you need.
However, here are very simple instructions for using software already a part
of Win95/98:
First connect to your ISP as you normally do when using the internet. Click
Start then click Run. In the box enter "telnet 209.32.226.63" (without the
quotes of course). Now click OK.
You should now be connected to the KC0DJO AR-Cluster.
Enter your call. If what you type does not display, then you will have to
turn on local echo. In the Telnet window click on Terminal / Preferences..
and check Local Echo and then click on OK.
Now proceed as earlier described to sign on.
Try some common commands as:
SH/DX
SH/C

Subject: Internet over packet?
While browsing information about packet radio, I found a site at
http://www.wa4dsy.radio.org/. This site was connected to the Internet
at 56k.
I was wondering if there was any way to modify this type of setup
so I could access the Internet from one TNC connected to my laptop
and another connected to a Linux box here at home. The Linux box
has a 28.8 modem and is a 486.
What is the minimum speed that both TNC's should support in order
to keep myself from tearing my hair out waiting for Web pages to load?
What other concerns should I watch out for (besides no business-related
stuff)? Maybe something which blocks out inapporiate language or maybe
a filter that blocks porn too?
And how do I make this setup work in Windows too? All I've seen is AX.25
stuff for Linux, which the laptop doesn't have.
