Ok, with my arduino woes out of the way, i can now focus on the transmitter part of the 3 band CW rig project. Cannot rush these things and i might even get this rig working before i die, well we all have goals to shot for. LOL.
So what do I need and how are we going to go about it. For a start I am a paddle guy, single lever paddle to be precise so I need some form of built in electronic keying. A fixed speed is all i need, say 15wpm, most of the people I work from parks are slower cw types so 15wpm is a nice speed. Memory keying would be nice as I will be using the rig mostly for WWFF or SOTA a basic CQ macro and CQ Sota and CQ WWFF are all i need build in. It needs to provide the sidetone and finally this needs to be able to key the transmitter on and off as well.
As far as arduino keyers go, the Arduino CW Keyer by K3NG is probably the duck nuts. Fully feature rich and does everything other than be the other half of your contact. I looked at it, tested it and its bloody awesome, but i really do not need all that complexity so I have decided to roll my own.
So i assembled some bits and bobs and started to write some code. I have it sending nice perfect 15wpm code already using the Piezo as the speaker. I probably will not release this code. I think if you want a full fledged keyer use the one by K3NG and if you are like me and just need a simple keyer for your project, then its time to man up and write some code. It is really not that difficult at all.
