Both methods work well. Be sure the unit is mounted to some sort of heatsink,chassis, etc. I'm using a Fury GPS receiver to drive the EFC on an LPRO-101. You won't get much range out of either adjustment. Leave it powered on for a couple of hours before trying to adjust it. I usually set the trim pot in the middle of it's range and use the EFC pin. I think it's a 28 or 30 turn pot. EFC is 0-5v. The unit will self-bias to around 2.5v if the EFC pin is open.
