Yesterday I finished building the Brendon TCVR. Now I only need to find a suitable Dynamic Mic to test the radio. I have already tested the receiver and it works very well. The first station I heard was LA9XV.
I have ordered parts to build a simple audio oscillator to align the radio before going on the air. I'm also waiting for the linear amplifier kit to arrive but will test the radio at 1,5W before adding the amplifier.
I found the building instructions easy to follow and I especially liked the test procedures after each building step. This way the builder can be confident that the previous sections are working before a new section is added.
