Alan, good video! thx.
SSB installation and troubleshooting is sometimes tricky. I made my engineer's degree in electronics and telecommunication and are an active HAM radio user since many years, but - even beeing a kind of professional in this area - it took me some time to get my installation working fine. There are quite a few factors that might influence transmitting, also outside the active HF elements (e.g. compressor of the fridge...:-) ).
most important - imho - , if the ground is ok, are "connections", good soldering at the connectors and the right cables, and understanding that the antenna starts at the tuner :-)
