Tested the MOSFET/Cobra 148GTL with the Autek WM-1 watt meter and 50 ohm dummy load:

AM: 5w dead key swinging to 20w+.
SSB: 24w

The MOSFET barely gets warm with short keying. If you key up for 1 min, it does get a bit warm. That is with the bias at the stock EKL device/3.85v setting. Didn't get any 100k resistors yet; prolly tomorrow. Looks fine on the scope - too . . .
