Thread-topic: LF: 137.5kHz WSPR Tuesday evening - reports appreciated
The IRF510 gate voltage is set just below 3V with a resistive pot. The drive is not a square wave though, so I suppose this could be part of the issue?
Hello Roger,
 
Try higher gate voltage (> 8V) and square wave input signal. That way you will switch the FET fast enough.
