the ESC key switches between HCW (human CW) and CTX (computer texting) modes.
You will want the HCW mode.
To operate:
1. turn on the DMX-40
2. Press the frequency button so it says External
3. Make sure you are in HCW Mode (HCW: Collecting Data...). The ESC switches
between HCW and CTX.
4. Start tuning around looking for stations to decode on your transceiver.
5. You will use your normal routine to transmit. Note it is a good idea to have a dummy
load on the antenna connector of the DMX-40 so it will not pick up your signal. If it
still picks up your signal, you have a serious issue with RF in your shack, and you
need to attend to that.
6. Don’t forget to press SPACE at the beginning of a NEW CODE STREAM.
3. Decode and Encode#
If you do the complete setup as shown in Figure 8 above, you will be able to use both
your key and the automatic keying functions of your DMX-40, as well as the
microprogramming functions for customizing your operation mode.
Please review Sections I and II of this Quick Start Guide. Section I explains basic
function, and Section II explains the various CALL and ANS functions for automatic
operation in transmit mode.
Once you have these bases covered and understood, you can "break in" with manual
keying at any time, and you can also train yourself for better timing by keying to the
decoder while in receive mode on the DMX-40.
Note that transmit mode on the DMX while in External Mode simply means it is focused
on transmitting CW to your rig, and receive mode means it is listening to your rig’s
receiver output. This means that you will be using function keys or the CALL and ANS
buttons to transmit, just as if you were operating in QRP mode. But instead, you are
transmitting at a much higher power via your external rig, and (one hopes) you have a
much better receiver feeding the decoder.
To operate,
1. Turn on the DMX-40.
2. Press the frequency button so it says External.
3. Make sure you are in HCW mode (HCW: Collecting Data...). ESC switches between
HCW and CTX.
4. Tune around the band looking for a spot to call CQ or for someone calling CQ, etc.
