Plain-language answer: An SDR transceiver uses software-defined processing for both receiving and transmitting.
Why operators care
Transmit capability adds strict requirements for clean conversion, filtering, timing, amplifier linearity, control reliability, and regulatory compliance.
Set it up correctly
Verify supported modes, output filtering, latency, duty cycle, interface stability, and the behavior when software or network control fails.
The common mistake
Treating transmit software as a harmless display setting instead of part of the RF control chain.
Operating boundary
Current regulations, service documentation, satellite status, software versions, and the complete station’s continuous-duty limits control. Online reports are observations, not guaranteed link performance.
