.Receiver Noise Level
|
||||
|
||||
- If it is not already highlighted in green, click the *Monitor*
|
||||
button to start normal receive operation.
|
||||
|
||||
- Be sure your transceiver is set to *USB* (or *USB Data*) mode.
|
||||
|
||||
- Use the receiver gain controls and/or the computer's audio mixer
|
||||
controls to set the background noise level (scale at lower left of
|
||||
main window) to around 30 dB when no signals are present. It is
|
||||
usually best to turn AGC off or reduce the RF gain control to minimize
|
||||
AGC action.
|
||||
|
||||
.Bandwidth and Frequency Setting
|
||||
|
||||
- If your transceiver offers more than one bandwidth setting in USB
|
||||
mode, it may be advantageous to choose the widest one possible, up to
|
||||
about 5 kHz. This choice has the desirable effect of allowing the
|
||||
*Wide Graph* (waterfall and 2D spectrum) to display the conventional
|
||||
JT65 and JT9 sub-bands simultaneously on most HF bands. Further
|
||||
details are provided in the <<TUTORIAL,Basic Operating Tutorial>>. A
|
||||
wider displayed bandwidth may also be helpful at VHF and above, where
|
||||
JT4, JT65, and QRA64 signals are found over much wider ranges of
|
||||
frequencies.
|
||||
|
||||
- If you have only a standard SSB filter you won’t be able to display
|
||||
more than about 2.7 kHz bandwidth. Depending on the exact dial
|
||||
frequency setting, on HF bands you can display the full sub-band
|
||||
generally used for one mode (JT65 or JT9) and part of the sub-band for
|
||||
the other mode.
|
||||
|
||||
- Of course, you might prefer to concentrate on one mode at a time,
|
||||
setting your dial frequency to (say) 14.074 for FT8, 14.076 for JT65,
|
||||
or 14.078 for JT9. Present conventions have the nominal JT9 dial
|
||||
frequency 2 kHz higher than the JT65 dial frequency on most bands, and
|
||||
the FT8 frequency 2 kHz lower.
|
||||
|
||||
.Transmitter Audio Level
|
||||
|
||||
* Click the *Tune* button on the main screen to switch the
|
||||
radio into transmit mode and generate a steady audio tone.
|
||||
|
||||
* Listen to the generated audio tone using your radio’s *Monitor*
|
||||
facility. The transmitted tone should be perfectly smooth, with no
|
||||
clicks or glitches. Make sure that this is true even when you
|
||||
simultaneously use the computer to do other tasks such as email, web
|
||||
browsing, etc.
|
||||
|
||||
* Adjust the *Pwr" slider (at the right edge of the main window)
|
||||
downward from its maximum until the RF output from your transmitter
|
||||
falls slightly. This is generally a good level for audio drive.
|
||||
|
||||
* Toggle the *Tune* button once more or click *Halt Tx* to stop your
|
||||
test transmission.
