Asking for a friend...
who's having trouble sending a digital signal from the digital output of microcontroller to a transceiver. The signal looks good at both the uC and the end of the connector cable (a ~1.5m coax cable), but when it's connected to the transceiver it disappears. The input on the transceiver is a transistor with a resistor in series.
Any observations as to what might be happening? Wish I could provide a schematic but apparently it's "confidential", I can probably make up a simplified version once I actually see the circuit. Thanks.
