Tony,
Thank you for your great contributions to our hobby. A 40-30-20 RXTX was my introduction to the world of SDRs. Many hours were spent learning how to set up and effectively use my RXTX in CW Mode. A modification engineered by members of this forum allowed me to use my RXTX in CW Mode with HDSDR utilizing semi-break-in with a real time side tone, making it very useful during many CW events.
My 15-17-10 RXTX has been sitting here patiently waiting for this new sunspot cycle to mature so that I can put it to work.
Enjoy your retirement and your place in the history of ham radio,
73,
Jody - K3JZD
