Post help with bly89 schematic Reply with quote
Hi,

I am now going to try my luck with this schematic. There is however a modification i would like some help with. I would like to implement a gain control, and would like some help with this. The amp will be driven with a 1watt drive. could i some how limit this input to act as a gain control. I dont want to put any unwanted load on my 1 watt drive (i.e the transmitter) i aslo dont want to upset the 50ohm inpedence.

thanks adam

Easiest way to control power output will be to
alter supply voltage. An adjustable power supply, so to speak.
