Tips for eXtreme CW Operators
Introduction
To survive in an otherwise QRO world, QRP operators and
those with restricted space for antennas learn to become patient; dedicated; and
tenacious. Without these qualities, they would give-up.
It is for this reason that such operators invariably make
excellent eXtreme CW (XCW) operators.
eXtreme CW may be defined as the use of conventional morse code
communication under difficult operating conditions. Such difficult conditions
may be due to very weak signals; continuous or intermittent local interference;
or due to co-channel interference (for example, from intruders in the
IARU CW-Only segments).
Basic Techniques
XCW techniques include:
- the judicious use of slow CW (down to, say, 12 wpm);
- full break-in operation to send characters/words during breaks in QRM;
- very accurate netting (+/- 20 Hz);
- very narrow receive bandwidths (<100 Hz);
- sending 'XCW' so that the other operator knows that you're keen to get the
message through;
- message repeats; and,
- repeated 'R' to confirm message receipt.
