I have loved RTTY since I was a young ham. Had a Western Electric RTTY machine in my bedroom as a kid. My parents house was a pier-beam type of construction and when that machine was marking time it would set up a standing wave on the floor that would shake that end of the house. Fortunately, my parents loved the kid’s radio hobby – I was pretty lucky…<\/em><\/p>\n

The story of the evolution of the amp is explained in the page below. But it’s still a work in progress. I sure hope that this year I can complete it before the fall contest season heats up. Unfortunately, it was not until I had the amp for a few weeks that the RTTY “bug” bit me hard – otherwise I don’t think I would have ever selected the SB200 as a platform for an RTTY amp project.<\/em><\/p>\n
