About Modo

Gerry Moersdorf (Modo) KC8ZUL


 Hi. I’m Gerry Moersdorf and welcome to my site.  I am a major fan of  ham radio and all types of electronic equipment.  I’ve owned several  companies in the industry. Software Results and Applied Innovation where  we worked with some pretty cool stuff.  I also have some pretty big  AM 1,000 watt rigs I restored and updated and put out some serious signal.  My callsign is KC8ZUL and I live in Delaware, Ohio.

My Motto:

If it isn’t heavy enough to kill you if it falls over, don’t use it.

The KC8ZUL station is located in Delaware, Ohio. At 975' above sea level it is a great place to work other stations all over the country, and the world. This is also the location of my collection of restored AM broadcast transmitters

The Early Days, Software Results, Applied Innovation.

 I’ve owned several companies in the electronics industry. We did a lot of interesting work, together with great folks, building great products. See even more companies, and projects below.
