My bike is a bit of a boatanchor. It was made in Japan. I bought it 22 years ago when I was in Spain. I’ve used it in Spain, The Dominican Republic, the UK, Portugal, Italy, and in the U.S.<\/span>

Of course, my thoughts have turned to putting some sort of HF radio on the bike, probably just a receiver. I still have a little handle-bar AM radio that I added shortly after I bought it. The handle bar mount is still good. See above. I’m pleased to see that it looks very simple, with discrete components. The AF amps are obviously off to the left of the speaker. To the right of the speaker we obviously have the RF and IF circuits. There are some nice tuned transformers there (from the “Chop Shing” company), and three transistors and a diode. What would the standard lineup be for a simple AM radio of this type? Maybe just an RF amp in the front end, a local oscillator, one stage of IF amplification and the diode as the detector? <\/p>\n

What do you guys think? Make use of some of the existing circuitry? Start over?
