[WriteLog] 4N33's For Sale

[Marty Tippin]

(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,
