Timewave PK-232MBX - 7.3 Transmitter Adjustments

PK-232 MBX – OPERATING MANUAL AMTOR AND NAVTEX OPERATION
4/91 7-4 89
After you have an FEC AMTOR station tuned in, you should start seeing the copy on your
screen. If you have tuned in "chirping" ARQ AMTOR stations, you will not print anything
until you enter the ALIST mode. If you just want to receive, see Chapter 10 on SIGNAL
IDENTIFICATION.
7.3 Transmitter Adjustments
Make sure your PK-232 is adjusted for your SSB transmitter as described in section 3.5 and
3.5.2 of this manual before transmitting.
These are very critical adjustments. If your PK-232's AFSK level and transmitter microphone
gain are not adjusted properly, other stations will not be able to copy your signals. Check
your plate or collector current or the power output of your rig before going on the air.
7.3.1 Going On The Air
Make sure your transmitter and antenna are tuned and adjusted for the band and operat-
ing frequency you are using. Before you transmit, you must decide if you are going to
"call CQ" or answer someone's CQ call.
7.3.2 Calling CQ in FEC AMTOR
If you plan to make a CQ call, you must do so in the FEC AMTOR mode. This is required
since an ARQ AMTOR transmission requires another station to "Link-up" with. If you are
using an AEA PAKRATT program, see the program manual to place the PK-232 into FEC
AMTOR transmit.
If you are using a terminal or terminal program, the following will place your PK-232 and
transceiver into the transmit mode.
o Type FEC then press the <Enter> key to key your transmitter and automatically
enter AMTOR FEC transmit mode.
As soon as you type the <Enter> key you will be transmitting! At this point you are also in
the CONVERSE mode and anything you type will be sent in FEC by your transmitter.
o Type in your CQ message. Make sure you include YOUR Callsign, your four-character
Selcall (MYSELCAL) as well as your sevencharacter Selcall (MYIDENT) so others can
respond to your CQ call.
An example is shown below:
CQ CQ CQ CQ CQ CQ CQ DE N7ML (NNML) (VTMFFFF)
CQ CQ CQ CQ CQ CQ CQ DE N7ML (NNML) (VTMFFFF)
CQ CQ CQ CQ CQ CQ CQ DE N7ML (NNML) (VTMFFFF)
CQ CQ CQ CQ CQ CQ CQ DE N7ML (NNML) (VTMFFFF)
SELCALL NNML (VTMFFFF) K
<CTRL-D>
o Type <CTRL-D> at the end of your CQ call. The <CTRL-D> puts both your radio and
the PK-232 into the receive mode.
o Wait a bit to see if you get a response. If not, you can repeat the above procedure.
