I'm Having Trouble Connecting
If the station you are trying to connect to is connected to someone else, you may see the
following message:
*** BUSY from (Callsign) DISCONNECTED
If you see this, simply wait a few minutes and try again or try connecting to a different
station from your MHEARD list.
If the distant station cannot hear you, you may see the following:
*** Retry count exceeded
*** DISCONNECTED:
A number of different things can cause this to occur. It may simply be that the station you
are trying to connect to is out of your transmitter's range. It is possible however that
something more serious is wrong, so you should check the following before proceeding:
o The Loopback Test in section 4.2 functions properly.
o Your PK-232's AFSK Output Level control, your microphone gain, and deviation are
set properly as discussed in Section 3.5.1.
o All cables and connectors are properly installed.
o The RADIO 1/RADIO 2 switch is set for your cable-to-radio setup.
o Your radio's volume and squelch are set for local conditions.
o You are following the correct procedure for Connecting. Remember that this proce-
dure is slightly different for AEA PAKRATT programs than it is for terminals or termi-
nal-programs.
o The "HBAUD" parameter is set to "1200" for VHF/UHF Operation.
o The "VHF" command is "ON" for VHF/UHF operation.
o RESET the PK-232 with the RESET command.
If none of the above correct the problem, ask one of your area's experienced Packet oper-
ators to listen to your transmissions. Both you and your partner should set MONITOR and
MCON to 6, and then send some packets. Each station should display packets sent by the
other.
o If only one station is "hearing" packets, check the modulator and transmitter of that
station and the demodulator and receiver of the other station.
o Experiment with the TXDELAY parameter for the sending TNC. Try setting TXDELAY
64 for a long delay. If this solves the problem, decrease TXDELAY to the smallest
value that works all the time.
If none of the above allow you to connect to other stations, then you should contact
Timewave Technical Support before proceeding.
4.4 More Packet Features
Now that you have worked a few Packet stations, it is time to learn a little more about the
other packet capabilities of the PK-232. Rather than explain all the features in detail, we will
leave the specifics to the command descriptions in the Command Summary Appendix.
