In the spring of 2009 I purchased N8LP's LP-Pan Panadapter and needed a better computer in order to run the SDR programs like NaP3 which could utilize that hardware. I decided I would build myself a speedy computer to do just that. I researched and purchased all the parts necessary and then on July 3rd I broke my right leg really bad. I was in a wheelchair for 4 months after spending about 16 days in the hospital. During all this the computer parts just got shoved under the bench and left there for about 7 years! Recently a friend put it all together and I have a nice (essentially new) XP Pro SP3 computer with 4 GB of RAM. Since XP is really not supported anymore, I decided to utilize this computer for my digital operations thus keeping those separate from the computer I use for Internet surfing, email, etc.
|Serial PTT Circuit|
|Completed Wiring of the Circuit|
It did not take much time to wire up the parts and you can see the completed Serial PTT circuit on the right (click on any image to see it larger.) I chose to use the RTS line but I could have used DTR just as easily. I only need to tell the WSJT software the COM Port number and click on the RTS button to allow the software to communicate with the microKEYER II.
A quick check of the circuit by telling the WSJT program which COM port to use and plugging the cable into the Footswitch input of the microKEYER II and, VOILA! I can now key the K3S from the newly-built XP Pro computer - SUCCESS!
