| November 23, 2011 - An APRS iGATE was installed using N9CHA-4 as the call sign on 144.39. The installation resides along side the Winlink RMS node. Chris KC9NVV, Mark KC9GHQ and Greg N9CHA installed a Win2000 computer which was donated by Steve NØXC. The system is running the latest version of UI-View and is configured to "gate" local APRS users into the network. A Netgear FS105 5-port switch was also installed to allow internet access to both the Winlink RMS computer and the iGATE. An Icom IC-2AT FM HT is being used for the transceiver along with a TNC-X as the TNC. The iGATE is utilizing the VHF antenna mounted to the tower on top of the Government Center penthouse. |
|
| March 29, 2011 - The Winlink RMS was installed and placed into service by Mark KC9GHQ, Chris KC9NVV and Greg N9CHA. The system in running at the Polk County Government Center in Balsam Lake. Callsign: N9XH-10 on 145.01. |
| January 16, 2011 - A UHF beam antenna was installed and placed into service for the UHF link between the tower shack and the radio shack. The radio shack radio was changed from an Icom IC-2720 to a Kenwood TM-V7. This radio was donated by Bud KB9ZAZ's estate. |
Packet Mail Addressing
A packet bbs such as W9ABA has a very powerful mail handling capability. It is very simple to use with the list, read, send, and kill or delete commands. But in addition, there is a behind the scenes programming that can forward and reverse forward messages to full service packet BBS stations.
The simple mail message is sent using the send command. ‘send callsign’ will start a message to callsign. The usual subject and text prompts follow. This message stays at the bbs until the recipient connects, reads, and kills the message or the sender connects and kills the message. Only the sender, the recipient, and the bbs sysop have the privilege to read and delete the message. Local messages can be forwarded on to a local tnc pbbs. Send a message to sysop to arrange local forwarding.
More complex addressing can be used to send messages to distant packet stations. h-addressing or hierarchical addressing can route a message to a full service bbs and beyond. In a simple form, send callsign@bbs will instruct the bbs to forward this message to the station bbs. An example will be send n0mr@n0mr. That message to n0mr will go to the bbs n0mr.
A more complete address would be mailto:callsign@w9aba.#wcwi.wi.usa.noam. An example would be n0mr@n0mr.#nemn.mn.usa.noam or kc8emf@kb8hhq.#upmi.mi.usa.noam. That address includes the callsign, bbs, area, state, country, and continent. These addresses will not work as internet e-mail addresses.
Even more distant mail transfers can be made throughout north and south America and even Europe and Asia. All you need is the proper address. In this area, any address that is outside the area of MN, WI, and MI will go to N9PMO and be sent out from there.

| July 23, 2010 - Both Alinco radios and KAM XL TNC are powered by the MSR2000 Repeater power supply and battery backup. The DC power distribution panel, RigRunner 4002, is connected directly to the 90 Amp/Hr battery terminals. Should a power failure occur, the packet system will continue to operate. (The N9XH-10 APRS equipment is also powered from this DC power source.) The Astron 20 amp supply has been disconnected but remains at the tower shack on stand-by if needed. |
| June 23, 2010 - A KAM XL Dual-Port TNC was placed into service along with VHF and UHF Alinco transceivers. Both VHF and UHF are operating on AX.25 1200 baud. Cross connects between the ports on the TNC are now possible. It was determined the most efficient use of equipment and spectrum was to install a dual-port TNC so that during communication events, an operator in the PCARA Ham Shack could easily access the N9XH packet network without causing possible interference to a control operator on 2 meters. The UHF link into the network eliminates the potential interference and makes data through-put sustainable. |

| Software: Winlink 2000 (WL2K) is a worldwide system of volunteer resources supporting e-mail by radio, with non-commercial links to internet e-mail. These resources come from Amateur Radio, the Military Affiliate Radio Systems (MARS), and other volunteer organizations. The system provides valuable service to emergency communicators, and to licensed operators without access to the internet. |
| Software: Outpost is a Windows-based packet message client that lets you send and receive packet messages with almost any Amateur Radio Bulletin Board System (BBS) or TNC Personal Mail Box. Outpost was designed for the ARES/RACES packet user community. The thinking behind it was to create an intuitive, easy-to-use program that lets ARES/RACES organizations focus on the "message," not the "medium," as they pass packet traffic to and from an Operational Area BBS. |

Let's Enjoy This Stuff!
I'd like to preach about a few ways to DO packet as sometimes so much
stuff goes past us in emails, we don't always have a chance to digest it.
I've heard comments from some that say to me i that i need to try to
explain some stuff. So here goes... There are a few ways to setup a packet station.
One way is to just hook a TNC to a radio and computer with a simple
terminal program such as Hyper terminal, Winpack, Outpost, etc. This works fine if you ONLY use TERMINAL programs on your TNC. IF you want to use Winlink programs WHICH WE WANT YOU TO!!! (RMS Packet,Paclink,Airmail) also, that gets a bit more complicated.
You see, Winlink programs are a different animal. They are fancy high
level programs that, when they are started up on your computer, go into
your TNC and start changing stuff. That is what the .INI files in each
program are for. These programs change your TNC from TERMINAL mode to either KISS mode or HOST mode. Plus, they talk to your email program
in TCP-IP or some such nonsense and allow you to send email over packet. Complete with fonts, attachments, and formatting. Whoah baby!!!
Doing this enables the PROGRAM to do all the thinking and just use your
TNC as a dumb modem. If you just run Winlink programs on your computer, and NOTHING else, you will probably do fine.
Problems happen when you SWITCH between programs. WHY??? Because Winlink programs for some strange reason don't exit pretty. They go in, change your TNC to KISS mode, and then when you exit out of them, they LEAVE the TNC in KISS mode. And you are sad because your TNC wont initialize, and you want to run your TERMINAL program!!! So, to get it back, You either hard reset your TNC, and reenter a bunch of parameters or do some weird tricks i wont describe here.
But what if you want it ALL? You want to run Outpost, Paclink, RMS
Packet, Winpack, ALL at the same time. Enter AGWPE ------AGW Packet engine. What this wonderful program does is allow you to run all of these
programs on ONE TNC. Plus, if you want a program to control more
than 1 TNC, you can do that too, by setting up multiple PORTS on
AGWPE. I use the packet engine on my computer, and run Outpost,
Paclink,Winpack,and RMS Packet.
If i wanted to run a separate radio and TNC, and do APRS on a different
freq., AGW would route those packets also through another AGW port.
Then, I could ALSO have an APRS program like UIVIEW running also. That might
just happen soon!
The guy that wrote AGW has written a bunch of companion programs that
are
made to work WITH AGWPE: I'm just going to name a few. Go to the AGW
site and explore. AGWTERMINAL, AGWMONITOR, and one i just found out about that I REALLY LIKE---AGWUIDIGI.
WHY do i like UIDIGI? Well, two things you lose when you use the
packet
engine is the ability to have a mailbox and the ability to be a node.
(however, there are now AGW programs that give YOU a mailbox too.. I
prefer Outpost.. but that's just ME )
But AGW UIDIGI gives you the ability to DIGIPEAT. Say D-I-G-I-P-E-A-T.
It allows others to use your station to get to others. AND vis versa.
Which in our area is a GOOD thing. In an emergency, having redundant
digipeaters can mean the difference between having a reliable route or
not. If you are a portable station at some shelter or hospital, you
want OPTIONS!!!
THATS why I preach redundancy. If we all had 200 foot towers with
Stationmasters on them we could do with less. MAYBE!
I cant get to Ed's place by bouncing through WIPOLK all the time. But
if i could DIGI through Fred's or Johns station, maybe that would do it.
This message is way long, and i have so much more to say. (QUICK, SOMEONE STOP MARK... He's talking about PACKET again...!!!)
Just to whet your appetite, much of packet has moved to APRS. and we haven't even BEGUN to explore that. MORE than just vehicle tacking. Quite a mode and because of the extensive network out there, your
little station gets alot of bang for your buck. And then there's IGATES. But
that's for another time. And then there's OUTPOST. My all time favorite packet program.
Well, this has been fun. Lets enjoy this stuff.
