I’m still tinkering around with my superhet receiver. The plan is to eventually turn it into a full transceiver, but I keep getting sidetracked. I did knock together a mic amp based on one of n6qw’s designs.
Here is the schematic.
Here is how it turned out.
It seems to work okay. I connected my d104 mic to it and hooked it up to the scope and the scope pattern looks good. I’ll eventually get around to putting it on the radio and testing it for real, but I keep getting sidetracked with other interesting projects.
