What If.... ?
If you have trouble connecting, take a few minutes to verify each of the following items.
Verify that:
o
The PK-88's AFSK Output Level control, your microphone gain and deviation are set
properly as shown and discussed in Chapter 2.
o
All cables and connectors are properly installed.
o
Your radio's volume and squelch are set for local conditions.
o
You are in Command Mode. (Type
o
If the
on again. You should get the normal sign-on message.
o
TONE is set to 3 (or 2) for VHF, 0 or 1 for HF.
o
HBAUD is 1200 if on VHF; 300 if on HF.
o
CFROM is set to ALL.
Ask one of your area's experienced packet operators to listen to your transmissions and
monitor with his TNC. Both you and the distant station should set MONITOR and MCON to
'5' or '6', enter Converse Mode and send some packets. Each station should display pack-
ets sent by the other.
o
If only one station is 'hearing' properly, verify the modulator and transmitter of that
station and the demodulator and receiver of the other station.
o
Experiment with the TXDELAY timing parameter for the sending TNC.
o
Set TXDELAY to 60 for a long delay. If this solves the problem, decrease TXDELAY to
the lowest value that works all the time.

Automatic Operation
The PK-88 offers a variety of automatic operating features including beacon operation, digi-
peater function and auto-answer messages.
Your Packet station can be a digipeater for relaying packets to a more remote destination.
Functions like CONNECT MESSAGE take care of situations not easily solved in modes other
than Packet. See the 'Command Summary' chapter for full details on the PK-88's com-
mands.
4.5.1
Beacon Operation
The PK-88 can send an automatic beacon message at specified intervals. A beacon text
can contain special announcements, or 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 bea-
con.
o
Set your beacon text using the BTEXT command.
o
Set the beacon timing interval using the BEACON EVERY or BEACON AFTER com-
mand.
For example, to transmit your beacon at 15-minute (15 × 60 seconds) intervals, type:
BEACON EVERY 90
cmd:
BEACON EVERY 0
