RX/TX sequencer

Lukas Fässler has designed and built an RX/TX sequencer based on a PIC16F18325,  that is available on github: Much like the beacon keyer presented here earlier, this RX/TX sequencer is a simple but useful little device. Its typical use is in ham radio applications when a separate power amplifier (PA) and/or a sensitive low-noise pre-amplifier (LNA) is used. […]
