4.7.6 Going On The Air<br />

Make sure your transmitter and antenna are tuned and adjusted for the<br />

band and operating frequency you are using.<br />

On HF there are two ways you can go about talking to another station.<br />

o<br />

o<br />

First, you can look at the packets you have just MONITORED<br />

(or in your MHEARD list) and choose one of them to connect to.<br />

You can also "Call CQ" by entering the CONVERSE mode and pressing<br />

the key a few times.<br />

Either way you decide to go on the air, remember that things happen<br />

much more slowly on HF packet than they do on VHF and UHF packet.<br />

HF packet requires patience and careful tuning in order to be used<br />

successfully.<br />

If you are having problems connecting to other HF packet stations, try<br />

working with an experienced HF packet operator in your area and listen<br />

to each other's signals. See if you can copy each other's packet<br />

signals. If he cannot copy your signals, have him listen to your<br />

signal in the CALIBRATE mode to make sure you are transmitting a pure<br />

tone. As mentioned earlier, any distortion caused by overmodulation<br />

or RF feedback will make your signal difficult or impossible to copy.<br />

4.8 Advanced Packet Operation<br />

You <strong>PK</strong>-<strong>232</strong> has many commands and features that are not used for dayto-day<br />

connects conversations. Still, as you become more familiar<br />

with packet, some of these features may become important to you.<br />

4.8.1 Transparent Mode<br />

One of these features is the TRANSPARENT mode. The TRANSPARENT mode<br />

allows any 8-bit binary character to be sent by your packet station.<br />

You usually must use the TRANSPARENT mode to transfer binary and<br />

executable files to and from other stations.<br />

You can either enter the TRANSPARENT mode by typing TRANS at the<br />

command prompt after you connect, or by setting the CONMODE command to<br />

TRANS. Either way, once you enter the transparent mode, any character<br />

you type will be sent automatically after the PACTIME setting. This<br />

way any character can be sent by the <strong>PK</strong>-<strong>232</strong>. Although we recommend<br />

using HARDWARE flow control in transparent mode, SOFTWARE flow control<br />

is available with the TRFLOW and TXFLOW commands.<br />

To get back to Command mode after you are finished with transparent<br />

mode, you must type the COMMAND character (default ) 3 times<br />

within the "Guard time" set by the CMDTIME command (default 1-second).<br />

4.8.2 Sending 8-bit Data in Converse Mode<br />

Sometimes you may need to send a file that contains some 8-bit data,<br />

but not need all the features of the TRANSPARENT mode. In this case,<br />

you may find turning the command 8BITCONV ON is all that is needed.<br />
