(It's been a few months since I last sent this out...)
I have a quantity of 4N33 Opto-isolators for sale - useful for building a
PTT or CW keying interface between the rig and your PC's serial port.
Better than just using a simple transistor switch as it isolates your
computer from any nasty voltages that might come from the radio on the
keying line.
Price:
$.75 each (any quantity), plus $.50 postage
Send an e-mail indicating how many you want and I'll send my mailing address.
73,
