USER'S GUIDE
o If only one station is "hearing" properly, concentrate on the modulator and transmit-
ter of that station and the demodulator and receiver of the other station.
o Experiment with the

value that works all the time.

Automatic Operation
Your PK-232 offers a variety of automatic operating features including beacon operation,
digipeater function and auto-answer messages.
Your Packet station can be a digipeater for relaying packets to a more remote destination.
Functions like the "connect message" take care of situations not readily solved in modes
other than Packet. See the "Command Summary" chapter for full details on your PK-232's
commands.
4.6.8.1
Beacon Operation
Your PK-232 can send an automatic "Beacon" message at specified time intervals. A
beacon can send special announcements, or send the "mail for" list in a bulletin board
operation. The values "0" to "250" set the beacon timing in 10-second intervals. "0"
turns off the beacon.
Set your beacon text using the

Proper beacon timing avoids cluttering a busy channel with unnecessary transmissions.
In the early days of Packet-Radio, the beacon was very useful to show your presence
on the empty Packet channels. With the growth of Packet-Radio, many users feel that
the beacons have outlived their usefulness and may be a source of interference to good
traffic flow. Use your beacon with consideration for other on the channel.
If you set the BEACON timing at a value considered to small for busy channels (less
then "50"), you'll see:
WARNING: BEACON too often
This warning appears in the Command Mode each time you type a command to remind
you that your beacon interval is too short; your beacon may be bothering other channel
users and it needs your attention.
