Homebrew MC1350P based SSB Rig - #9 Quick Progress Update

A short video looking at some minor changes to the audio and mic amplifiers. Also added was some switching circuitry to allow the BPF and follow on RF amplifier to be shared between the RX (antenna amplifier) and TX (RF pre-amplifier) circuits. The plan now is to start working on the RF power amplifier. Looking at the feasibility of using BLE1043 LDMOS devices.
