modem should also cause the transceiver to switch to Transmit. At this point, the

potentiometer on the modem (just to the right of the display) can be adjusted to set the

power level of the transceiver. A transmit power of 15 to 40 per cent of the rig's rated

power is recommended. (i.e. 15 to 40 watts with a 100 watt rig). Keeping the power at

this level does two things. First, it minimizes distortion due to clipping. Second, it

avoids excessive heating in the rig finals, since PSK is a 100% duty cycle mode. A

power meter is very handy for making this setting. Once the potentiometer has been

set, press F8 again to return to receive mode.

You should now be ready for transmitting PSK.

Pressing F10 will place the modem in transmit mode, but with a PSK idle tone being

generated (unlike the CW tone in TUNE). If you are ready to give it a try, Press F10. At

this point, anything that you type on the keyboard, will be converted into Varicode

characters and transmitted using PSK modulation. Pressing F10 again, with toggle

back to receive. When in TX mode, "TX" will appear at the top left of the display.

8) Macros

If you want to set up macros (pre-recorded strings of characters for subsequent

playback) before proceeding, now is a good time to do it.

For those already familiar with PSK operations, macro setup is similar to many of the

popular PSK programs.

Macro recording is initiated by pressing Ctrl plus the function key that you want to be

associated with your macro. Let's go through an example of entering your callsign into

EEPROM memory and setting up a CQ calling sequence, as shown below. (I'll use my

callsign in this example, but of course you should use your own!.)

a) Record your callsign into EEPROM ...

Ctrl-M

b) Record the CQ calling sequence into the F1 macro ....

Ctrl-F1 Ctrl-S cq cq cq de Alt-M k Ctrl-Q Ctrl-Z

Now play the macro by pressing F1 and see ...

Tx comes on, "cq cq cq de n2apb k", Tx turns off

You can also record the other station's call sign "TheirCall" in RAM (not in nonvolatile

EEPROM) by pressing Ctrl+T, TheirCall and Ctrl-Z to end the entry. To insert the other

station's call sign into a macro, simply use Alt+T in the macro. Then, when you play the

macro, the other station's call sign will be inserted into the macro. This way, whenever

you enter a new call sign using Ctrl+T, you do not need to re-record the macro to use

the new call sign.
