The JR1MAF PacketCluster Node System (1996.9)
(User Frequencies : 14MHz,50MHz,144MHz,430MHz,1200MHz)
1. The PacketCluster

The software written by AK1A, Mr.Dick Newell to build a realtime network system using the packetradio for the radio amateur. The network consists of multiple node-stations being linked serially and many user-stations connected to one of the node-stations nearby.

In this network,

a. You can get the list of all the stations who is connected to the system in that moment.

b. You can send message to any station who is in the net ringing a bell of his computer at realtime. ...."TALK"

c. You can send message to all the stations connected to specific node- station or all the node-stations ringing a bell of their computer at realtime........"ANNOUNCE"

d. You can send a e-mail to anybody in the net, and also you can send a bulliten for all......."MAIL, BULLITEN"

e. The most important feature of this system is to send a DX information ( frequency & callsign ) to all the stations ringing the bell of the computer at realtime. Thousand of DX'ers are participating to the net just for getting this merit........."DX SPOT"

The software has more and more useful funcions.

To get started, you need to install a terminal software for packet radio into your PC, and connect the cable bwtween the PC and a TNC(Terminal Node Controler....Converts degital signals from the PC into analogue signals just like as a Modem for the Internet). Then connect the cable between the TNC and the tranceiver at Microphone jack and Speaker jack. Once you have set up the system, you just try to connect to the nearest Node station(See the list below) and there you are. Many stations keep it connected all for 24 hours.

4. The history of the PacketCluster in Japan

In 1990, there were six nodes in Kanto-area(Plain area encompassing Tokyo and its environs), being linked each other.(There was some more history before then, but they were a kind of experimentation being stand- alone, like JA7RHJ.) Six nodes were JR1CTA, JH1ORA, JH1GTV, JA1PEJ, JR1MLU and me(JR1MAF). Total numbers of the users were very few, somewhere around fifty or sixty then. In that era, the PacketCluster had not obtained the "citizenship" of all the DX'ers in Japan, and there were lot of debate saying the system would make the DXing worthless and so on. Link status was really unstable then, and we were making a lot of effort to obtain a stable links on 1200MHz, and 430MHz.

In 1991, I succeeded to get a link with a node in Korea(HL9OS) using HF radio(14MHz) as the first-ever trial in Japan. At the same time a lot of DX stations came and got connected to the radio port on 14MHz(14.105MHz) as user, when the band propagates well. As a result, there were some users in JA, who "worked" with DX stations by "TALK" and get QSL card on 430MHz or 1200MHz.

In these situations, little by little, the existance of the PacketCluster spreaded out( I also wrote an article regarding the network for a few times in radio magazine, it had help the people to get close the net. ), and new node born one by one as the users were getting increased. As a next step, link route was spreading out in many directions.

The first problem was to obtain a link route to get beyond of Hakone pass ( Moutainfoot of Mt.Fuji, and is still very high.) to the west. It was very hard to get through via grandwave on UHF. JA1KSO, Mr.Ito resolved this problem by putting up a node on the top of the pass, and after this, the link route was rushed into western Japan.

The next problem was to obtain the route to the northern Japan. By that time, there started to run a couple of nodes in Hokkaido( Northern island of Japan ), and I had a link to JA8IYI via 14MHz although the link was really unstable. A few nodes opened in the Japan sea coasted area( North side of mailand Japan ) were still remained alone, then. JI7DUD, JA0UGY, and JE1CAY made a lot of effort to cut through the problem, and finally, a route from Gunma pref. to Nagano pref. was obtained and the link route beyond the Japan Alps were established. Nowadays, this link goes up to the most northern area of mainland Japan, in the Japan sea coasted area.

On the other hand, the link route which has spread out into the western Japan faced to the historical feud problem between the DX'ers in Tokyo area and the DX'ers of Osaka area. The link was stopped at Nagoya area, and unable to go far west on the grand wave. Meanwhile, many nodes were opened in Shikoku, Chugoku and Kyushu area(Far west from Tokyo and Nagoya beyond Osaka area), and they had a link to JA1BRK in Tokyo area via 10MHz now. Thus, when the band propagates well, the Japan's PacketCluster consists of more than 50 nodes, including the total users of more than five hundred.

Only Osaka area and Hokkaido Island are kept stand-alone still now, not involved with this widearea network covering all over Japan. I certainly hope that the several problems would be resolved, and very near future, the day in which a real nation-wide-network would be completed.

5. PacketCluster in the Internet (Web Cluster)

The PacketCluster which was born in the radio was reaching to the fact that it's difficult to maintain stable links with overseas node stations on HF radio with using 300bps packet, not the PSK, due to the tarffic which was getting increased day by day. The PacketCluster which OH2BUA built and started in the Internet was a revolution, because with that system everbody can get any informations from anywhere on the earth in the world with the 100% of certainty. The PacketCluster in the radio had been changing the value and meanings of the DX-hunting. The new system in the Internet changed them completely. With the new system, everybody can get all the informations regarding QRV of DX staions even if they are working and located in an area where we can never have propagations at that time. Many DXers who had been feeling somthing romantic in DX-hunting might be disapointed. Now all you have to do is just join in a line, waiting for the system will feed you. It appears to me that we would better to change the style of enjoy the radio, including DX-hunting itself.

For me, the DXing is not "DX/Awards hunting, including the DXCC", but is the excellent tools to know the people and exchange friendship with them in all over the world, far away out of Japan. (That is the origin of the word "DX"!!) Therefore, this revolution doesn't force me to do anything. This is the best tool to understand the band propagations for all bands at anytime. The PacketCluster in the radio is the best tool to maintain the friendship with all the menbers of the net by way of TALKs and MAILs.


6. Guide for opening Node station of the PacketCluster (using G8BPQ together)

To have the PacketCluster got more popular and developed, more and more node stations are expected to be born. If you would like to participate with this project positively, following steps will be needed.

Find and confirm the closest node station to your QTH, with which you could have a stable link directly, or via some digipeater station.
Ask SYSOP of that node, wether he could get a link with you or not, and if Yes, how.
Purchase the software of PacketCluster. (from XX Towers. Inc. as below)
Download G8BPQ-related softwares. (You can do it from the MAFNET)
Set the hardwares. (Personal conputer, TNC, Radio, Antenna)
Install and se the PacketCluster software.
Install and set the G8BPQ-related softwares.
Kick the system ON and open your node.

Let's start to explain how you can set up the most simple node system with 2 radio ports, using two TNCs.

(1)SOFTWARE

a. PacketCluster Software

With your Callsign, ask XX Towers. Inc. (by TEL or FAX or Mail)
Price is US$395.00 + shipping charge US$45.00 = US$440.00
814 Hurricane Hill Road, Mason, NH 03048 U.S.A.
Tel(603)878-4600 Fax(603)878-1102

b. G8BPQ Netrom Software

G8BPQ Ver4.08 BPQ408A.LZH (248KB): Download it from here !


(2)HARDWARE

P/C : PC-AT compatible machine with 486 or higher. Uninstall Win95 and install PC-DOS insetad.

TNC : Almost any TNC is OK. (one which has KISS mode is essential) One for the node link, and one for the user port.

TRX : Two set of radio and antenna, for node link and for user port.

ANT : Usually, a beam antenna for node link, and a GP for user port.


(3)Preparation and Installation of softwares

Please refer to the Manual for setting and installing the PacketCluster software itself. You may probably need a help of SYSOP of exsisting node station, as it is a little complicated.

Here I will explain what to do with G8BPQ-related softwares.

G8BPQ had not been needed till a couple of years ago. After DRSI stopped manufacturing PC*Packet Adapter System, which is a on-board TNC as a premise hardware for the PacktCluster software, only way to go is to use normal TNCs around us. G8BPQ works as a device dirver for the external TNCs through COM ports. However, this software does not exist exclusively for the PacketCluster, and therefore, it is a little hard to understand even if you could get it in your hand. So, I will explain what to do with it, providing a download capability of sample files for setting I made.

a. Download the G8BPQ-related softwares, and melt it. Many files will be melt out, but you will need follwoing files only.

BPQCFG.EXE
BPQCODE.EXE
PASSWORD.BPQ
SYSOPH.COM

DEDHOST.COM

b. Download sample files for setting.

(PC.BAT/BPQCFG.TXT/LINK.CON) SAMPLE.LZH (5KB)

c. Edit sample files

(a) Open BPQCFG.TXT with editor, and change "JR1MAF" in line 58 and 62 into your node callsign. Change also ID message (like a beacon) in line 75. After this, excute BPQCFG.EXE in the same directory to create BPQCFG.BIN automatically.

(b) Rename the part of "LINK" of LINK.CON to node callsign with which you get a link. (example : JR1MAF.CON) After this, Open this file with editor, and change the part of "LINKCALL" in line 3, 6 and 7 into the node callsign with which you get a link.

(c) Open PASSWORD.BPQ with editor, and change the password to your pre- ferable password. (AAAAA....A is a default password)

(d) Open SYSOP.DAT in C:\PACKCLUS of the P/C which the PacketCluster has been already installed with editor, and change the line which start with "SET/TNC" as follows;

SET/TNC1 DRSI 32/32

d. Install the files

(a) Copy PC.BAT to C:\

(b) Copy LINK.CON(one you have renamed) to C:\PACKCLUS\CONNECTS.

(c) Copy BPQCODE.EXE, SYSOPH.COM, DEDHOST.COM, PASSWORD.BPQ to C:\PACKCLUS

(4) Kick it ON

a. Using a terminal software, do as follows;

(a) Set MYCALL (Your node callsign).

(b) Set KISS ON.

(c) Set the communication speed between PC and TNC at 1200bps.

(d) Connect TNC and radio for node-link to COM1, and for user port to COM2.

b. To start the system, enter "PC" at DOS prompt.

c. To connect with a link node, enter "CONNECT LINK" (the part of LINK is a callsign, renamed at above (3) c. (b) Example : JR1MAF)

It will run OK with above procedure.
Using 2 port TNC (KPC-4, KAM, etc.), you can provide 4 ports in total with COM1 and COM2
With using COM port expand board, you can increase ports more.
Above setting is the most simple and standard. If you get used to it, you may change many setting according to DOC files for BPQ.
