- Select *WSPR-2* from the *Mode* menu. The main window will
|
|
reconfigure itself to the WSPR interface, removing some controls not
|
|
used in WSPR mode.
|
|
|
|
- Configure the Wide Graph as suggested in the screen shot below.

- Use the mouse to set the width and height of the main window as
|
|
desired.
|
|
|
|
- Select an active WSPR frequency (for example, 10.1387 MHz).
|
|
|
|
- Click *Monitor* to start a WSPR receiving period.
|
|
|
|
- If you will be transmitting as well as receiving, select a suitable
|
|
value for *Tx Pct* (average percentage of 2-minute sequences devoted to
|
|
transmitting) and activate the *Enable Tx* button.
|
|
|
|
- Select your Tx power (in dBm) from the drop-down list.

=== Band Hopping
|
|
WSPR mode allows those with CAT-controlled radios to investigate
|
|
propagation on many bands without user intervention. Coordinated
|
|
hopping enables a sizable group of stations around the world to move
|
|
together from band to band, thereby maximizing the chances of
|
|
identifying open propagation paths.
|
|
|
|
- To enable automatic band-hopping, check the *Band Hopping* box on
|
|
the main window.
|
|
|
|
- Click *Schedule* to open the *WSPR Band Hopping* window, and select
|
|
the bands you wish to use at each time of day.

|
|
- Band-switching occurs after each 2-minute interval. Preferred bands
|
|
are identified with time slots in a repeating 20-minute cycle,
|
|
according to the following table:

|
|
- If the preferred band is not active according to your band-hopping
|
|
schedule, a band will be selected at random from among the active
|
|
bands.
|
|
|
|
- If the box labeled *Tune* is checked for a particular band, _WSJT-X_
|
|
transmits an unmodulated carrier for several seconds just after
|
|
switching to that band and before the normal Rx or Tx period
|
|
starts. This feature can be used to activate an automatic antenna
|
|
tuner (ATU) to tune a multi-band antenna to the newly selected band.
|
|
|
|
- Depending on your station and antenna setup, band changes might
|
|
require other switching besides retuning your radio. To make this
|
|
possible in an automated way, whenever _WSJT-X_ executes a successful
|
|
band-change command to a CAT-controlled radio, it looks for a file
|
|
named +user_hardware.bat+, +user_hardware.cmd+, +user_hardware.exe+,
|
|
or +user_hardware+ in the working directory. If one of these is found,
|
|
_WSJT-X_ tries to execute the command
|
|
|
|
user_hardware nnn
|
|
|
|
- In the above command +nnn+ is the band-designation wavelength in
|
|
meters. You will need to write your own program, script, or batch file
|
|
to do the necessary switching at your station.
