40m DSB Talkie Walkie

I usually regret posting about something before I even know its working, I mean this blog is littered with the dead corpses of so many projects it probably should be called Robs Graveyard. Anyway, I thought i would post about where I am at with the 40m DSB Talkie Walkie. Other than having one small thing to test, everything has worked as designed.

Shock horror I know, but mayby after 5 years of killing parts, I am finally getting the knack. I have compacted the boards into 2. Yeah i could fit it all on the one board and in a future edition I might just do that, but for now I see a lot of advantages in keeping all the digital stuff on its own board with header interconnects.

All i am left to do is to send them off to China and have them made, build, test and make QSO’s with it. Wish me luck.
