PF9Z - Steppir SDA-100 interface

Hi guys, I did build in a interface for my SteppIR controller SDA-100 for making a connection with my transceiver. So the fine thing is that you now can autotrack the frequency of the radio's VFO into the controller. Feel free for asking me some questions or just write me some email if you need some help. 73s and please hit subscribe!!! Sascha de PD9Z
