Wow. Looks more like an episode of Miss Marple with all the detective work of what is going on right down to the transistor with internal resistors and the redulting partial switching of tx and rx. A lot of effort and brain power going into that rig.
Hi George yep she’s certainly coming along and I am feeling a lot more confidant. I need to track down some of the parts and it could be a while before they get here as I’m looking for equivalents for the KEC switching transistor as I can’t find any UK suppliers as they only seem to be available in Asia. The 2SC2078 I have now ordered but not sure when it will arrive.
