Hello and welcome to KM5TZ's website.
Here you will find details on some of my Ham Radio projects, BMW car projects and other stuff I work on...
I enjoy building my own ham equipment, restoring vintage tube gear and fixing up BMW's. Although I don't do much with it anymore, I have a small business repairing and reselling electronic test equipment.
Above is one of my favorite receivers... a Racal RA-17L that I lugged back from the UK (back in the days when you could show up for a flight with just about anything). I checked it in at the baggage counter and received it at the other end with absolutely no problem! I completely rebuilt this one and upgraded the audio output section (stock output is only 50mW) to a 6AQ5. It has exceptional AM performance. I worked for Racal after graduating University which might explain my connection to it but by then technology had moved past vacuum tubes.
The speaker above the receiver is an early RME speaker, it's a really great sounding speaker for AM.
