Homebrew sBitx burn in complete - on to the SWR meter and RTC
|
Hi all -?
After a fun weekend working the 13 Colonies (clean sweep on HB sBitX- I think I win that section of the contest!) - I am turning to the final bits and bobs of the build, the SWR bridge and the RTC.? I build the directional coupler today.? ?I ran in to trouble trying to compile the swr_bridge.ino for the ATTYiny85.? I initially couldn't find the correct board manager.? ?If interested I posted the answer on the swr_bridge.ino thread. I should have the SWR bridge working tomorrow.? The RTCs arrive tomorrow and that *should* also be straight forward.?? I've ordered a couple of wood project boxes from Bezos and plan to shield with copper tape, N2CQR style - thanks Bill. Socketry is the worst part of a homebrew project! Here is the directional coupler.? I'm getting good at building these - I led a Vienna Wireless Society Makers group project in a stand-alone swr/watt meter project a few months ago - using essentially the same bridge circuit with my own AtTiny code. 73, Dean KK4DAS |
