4.4.4 Digipeater Details<br />
You may wish to connect to a packet station that is beyond your direct<br />
radio range. If a third packet station is on the air and both you and<br />
the station you want to talk to are in range of that third station,<br />
the third station can relay or "digipeat" your packets. You simply<br />
set the "digipeater" routing when you connect. Here's a sketch that<br />
shows how digipeating can solve problems:<br />
WX2BBB<br />
/ \<br />
WX1AAA _______/ \_________ WX3CCC<br />
You are station WX1AAA - you want to have a packet QSO with WX3CCC.<br />
But there's a mountain between you and WX3CCC; you're out of simplex<br />
range of each other. However, you know that there's a packet station<br />
located on the ridge - WX2BBB - which is in range of you and WX3CCC.<br />
Instruct your <strong>PK</strong>-<strong>232</strong> to set up a connection to WX3CCC using WX2BBB as<br />
an intermediate digipeater. When you initiate the Connect, type:<br />
"CONNECT WX3CCC VIA WX2BBB."<br />
WX2BBB has turned off his station, but you can still contact WX3CCC by<br />
going around the mountain through WX4DDD and WX5EEE as shown:<br />
xxxx<br />
/ \<br />
WX1AAA _________/ \__________ WX3CCC<br />
. .<br />
. .<br />
WX4DDD . . . . . . . . WX5EEE<br />
This time, type the connect command like this:<br />
CONNECT WX3CCC VIA WX4DDD,WX5EEE<br />
Type the digipeaters' call signs in the exact order of the intended<br />
path from your station to the station with which you wish to connect.<br />
You can specify a routing list of up to eight intermediate stations.<br />
In practice this does not work very well, and Networking Switches such<br />
as NET/ROM have replaced digipeating for the most part. Still, it is<br />
sometimes necessary to digipeat through one or two stations.<br />
4.4.4.1 Are You a Digipeater?<br />
Your packet station can be a digipeater for other stations. You don't<br />
have to "do" anything - your <strong>PK</strong>-<strong>232</strong> will digipeat other stations -<br />
unless you tell it not to! with the DFROM command.<br />
If your transmitter is keyed when you're not using it, or during lulls<br />
in your own conversations, you're being used as a digipeater by some<br />
other stations. This won't bother your chat with your partner.<br />
If you wish to monitor the other stations that are using you as a<br />
digipeater then set MDIGI ON.<br />
