Mode
OFF
This parameter determines the transmission mode during beacon operation. There are four
possible beacon modes:
OFF: The beacon mode is off, the transceiver is in ordinary manual operating mode
CW: the kit simply sends stored message 1 repeatedly, according to the configured Keyer speed,
and with message start timing determined by the Frame and Start parameters (see next sections).
WSPR: the kit sends WSPR according to the configuration parameters in the following sections.
FSKCW: the kit sends stored message 1 repeatedly in slow FSK CW, where “key-down” is shifted
up 4Hz and “key-up” is transmitted at the carrier frequency. The symbol duration is controlled by
the keyer speed, interpreted as the number of seconds for a CW “dit”.
If beacon mode is enabled (not OFF), the radio starts operating in beacon mode on power-up.
While beacon mode is operational, it can be canceled immediately at any time by pressing the
“exit” button. Remember that you should not have a GPS connected, when in ordinary CW
transceiver mode – it would key the transmitter since the GPS and paddle share the same
processor I/O signals – though if GPS protection is on (See Keyer menu), the radio will
automatically enter a “Practice mode” where no RF is produced.
Beacon mode is entered upon leaving the configuration menu system, if the beacon is enabled by
having this parameter set to a value other than OFF.
Frequency
14,097,140
This parameter determines the transmission frequency during beacon operation. In WSPR mode,
this is the frequency of tone 0.
It should be noted that the WSPR sub-bands on the bands are only 200Hz wide. You also need to
specify the correct frequency so that your transmission is inside the appropriate 200Hz sub-band.
QMX uses a 25MHz TCXO reference which is normally within a few Hz, so accuracy of the
transmission frequency is not normally an issue, even with no calibration.
Note that these are the actual transmission frequencies, there is no CW offset, no RIT, no other
modifications. The specified frequency is also DIFFERENT from the “USB dial frequency”
specified at WSPRnet http://wsprnet.org – the “USB dial frequency” is 1500Hz lower than the
actual transmit frequency, so that the decoded audio is at 1500Hz.
Therefore, ensure that for WPSR transmissions, you choose a frequency in one of the WSPR sub-
bands according to the following table (applicable only to the bands available in your QMX
version):
