I'm currently building a microphone adapter for my Yaesu FT-450 and for my studio mic. Adapter is based on the original one made by a fellow ham OH6HZH. I have been testing his adapter for couple of days now and it just works like a charm with my rig and mic. I'm using my AKG C2000B condencer microphone together with ART Tube MP microphone amplifier in this setup.

As I was buying some components for the adapter project yesterday, I also found the nice foot pedal (black box in the picture) from the local electronic shop. I installed it as foot PTT for this setup and it works like a charm. I have been running it with the "6HZH adapter". It just is a simple micro controller with nice plastic pedal... :-) Looking forward of having my own adapter ready in the upcoming days. More about it later...
