SharkRF openSPOT3, Руководство пользователя

Страница: 49 / 131

The openSPOT3 transmits an unmodulated carrier wave by default, so you'll only be able to hear it using a radio
which is capable of CW/SSB demodulation. You can turn on Audible CW ID , so the carrier wave will be
modulated, and you'll be able to hear it on a regular FM receiver. Note that if Audible CW ID is turned on, the
openSPOT3 transmits the CW ID without going to RX between dits and dahs, so you won't be able to transmit
using your transceiver while the CW ID is transmitted.
Before the openSPOT3 starts to transmit the CW ID, it waits at least TX delay seconds after the last received call.
An incoming call (both from a radio or from the network) will interrupt the CW ID transmission, so enabling the
CW ID does not interfere with the openSPOT3's normal operation.
Other modem settings
If Advanced mode is enabled, you can tweak various other modem parameters at the bottom of the modem
page.
The Call hang time setting specifies how many milliseconds the openSPOT3 will wait after the last valid frame
has been received to consider a call has been finished with a timeout.
If the BCLO level (BCLO - Busy Channel Lock Out) setting is not 0, then the openSPOT3's modem will only start
a transmission if it's RSSI meter does not measure a signal strength above the specified BCLO value in dBm.
