PK-88 OPERATING MANUAL
PACKET OPERATION
4 - 7
PK-88 - 54
EVERY sends your beacon text at regular intervals. AFTER sends your beacon once after
the specified interval after the last packet activity on the channel.
A beacon frame may be sent directly, and also sent via the digipeat addresses specified by
the UNPROTO command.
Thoughtful beacon timing avoids cluttering the channel with unnecessary transmissions.
Used with discretion, automatic beacons can be useful to verify propagation conditions
and show usable radio paths. However, excessive beacons can be a source of interference
to traffic flow. Use your beacon with consideration for others on the channel.
If you set the BEACON timing at a value considered too small for busy channels (less than
'90'), you will 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 may too short; your beacon may be bothering other chan-
nel users and need your attention.

Will You Accept Connections?
CFROM determines if call requests are accepted or rejected, which calls are accepted and
which are rejected. You can also use synonyms CONOK ON and CONOK OFF in place of
CFROM ALL and CFROM NONE. CFROM has four arguments: ALL, NONE, YES and NO.
ALL and NONE are used alone in the following manner:
o
ALL – the PK-88 accepts connect requests from all callers;
o
NONE – the PK-88 rejects connect requests from all callers.
YES and NO require a list of call signs:
o
YES (list) up to eight call signs whose call requests will be accepted;
o
NO (list) up to eight call signs whose call requests will be rejected.
CFROM's default argument is ALL. If ALL, the PK-88 will accept connect requests from any
station that sends you a connect request.
Type
CFROM NONE
or
CONOK OFF
to reject connect requests from all stations. If the PK-
88 receives a connect request when CFROM is set to NONE, your monitor displays:
*** Connect request: {call sign}
Your PK-88 sends the calling station a DM packet, or 'busy signal.' The caller sees:
*** {MYCALL} busy
*** DISCONNECTED: {call sign}
You can set the CFROM field to accept or reject call requests from specificstations.
To accept calls from one or more stations, type
CFROM YES
(plus a list of calls signs).
Connect requests will be accepted only from listed callers.
