You Wrote: "Couldn't get to K0BX's website late at night, perhaps pilot error, give it a try." The problem is the URL listed in your e-mail was incorrect. The zero in k0bx was an "o" instead of a zero. Please try: http://www.qsl.net/k0bx The goto CW Keying. BTW, the 4N33's are hard to find, but the 4N32 are easy to find. Work the same. But I have had better luck using the transistors but then everyone yelled at me as the transistors do not give as much protection to the port. But check out: http://www.megalink.net/~n1rct/rit2/pttfsk.html If you have problem getting or using the 4N33/32.
