On the SOTA “Joining in” webpage (http://www.sota.org.uk/JoiningIn) there is a picture approx halfway down of a Yaesu FT-817 resting on the stock microphone. However, it looks as if there is a rotary switch mounted on the mic.
I have searched the web for modifications to this mic and not discovered anything that looks close. I wonder if anyone out there knows what this is and would care to enlighten me!
Sorry for being just plain nosey!!
Be safe and have fun all.
Many thanks and 73
