First thanks to all those who encouraged me to wet my feet . Hope the wetted feet enjoy PBP before they turn their toes upwards....! Dave, my callsign as a Ham is ON4KJ since 1958 ( merely CW and contests )!! Have a look at QRZ.com and you'll find out somewhat more about, OS5N is my vanity call. IF I can find your e-mail, I'll tell you somewhat more about me! And now I'll get my wetted socks off! What comes next to PBPro? Hardware platform, what is " crossgrade " about, is " compile upgrade " a must etc. Take into account I still handle the soldering iron, and dispose of some discrete elements from an earlier live! But can't afford K$. Retired, and no Gov. in Belgium for instance, we dont know what will be next !!!! Thanks for reading me. All proposals will be welcome to make up my mind definitely. Jos.
