Keying interface for PC
Jim, N5IB
A few days ago I was reading Terry's (WA0ITP) description of a keying interface he made in order to use N3FJP contest and general logging software to send CW . His interface connected to a PC's printer port.
<http://www.wa0itp.com/cwinterface.html> With the demise of real serial ports and printer port on laptops, I decided to make an interface using a USB to serial adapter module that I had on hand. As long as it brought out the needed modem control lines (RTS in this case) it ought to work. I made a quick toner transfer PC board, and exercised my recently acquired 3D printer to make an enclosure. Attached is a PDF document of the project. It works fine - and just in time to get ready for November Sweepstakes. Additional support information can be found at <https://qsl.net/n5ib/> 73, Jim, N5IB

Question Related to My NS40 Transmitter
Bobby Drummond
If I add a 12 or 15 volt regulator in series with the 2N7000 oscillator transistor (to keep the voltage on it lower than the final's new voltage) and supply 24 volts to the IR510 circuit, will it handle the extra voltage? I assume it might need a better heat sink if so. I would also insert a DC switching circuit in series with the power to the transmitter so I would only be switching low voltage and low current DC voltage to effect the same thing as direct key switching. What would be the approximate power output from the transmitter be in that case? 73 de AK4JA

Back on the bench: built the SSCPO!
Picked up a SSCPO at the last convention and, need to have a code oscillator (and also dying to do something electronic!!), I built up the kit last night. It worked right off the bat and it sounded great with the built in key. I intend to build in a jack so I can use it with external keys. The only 'tweak' I had to make on the kit is to add two flat washers between the two spacers and the key strip to add some needed clearance between the key contact (i.e. the head of the screw holding the knob in place) and the pc board connection. A fun build and a great sounding code oscillator. 73 Bob Groh, WA2CKY
