[hpsdr] TR relay

[FRANCIS CARCIA]

Hi All,
I am planning to use an opto isolator as an interface to penny Driving a IR IPS solid state switch driving the coax relay coil. This will eliminate any chance of a relay coil transient comming back at Penny. The IPS switch will also control the final bias. I will be running a pair of MRF150s in a three stage modified MRI amp. I have used it on 160 with good reports using an EV664 mic. frank
