Re: Boombox protections? Work Boomerbox performance kicks?

I have replaced the ferrite bars in radios a few times when they got broken, like a dropped transistor portable, and a table clock radio that somehow had the bar broken. I just took the bars out of other radios that were about the same size and put them in.

I was thinking the radio wouldn't tune right if the bar was too much bigger or smaller than the original, finding out later that you can go bigger for more capturing power, just re-tune the trimmers on the tuning cap to peak the signal around 1400 khz.

Heck, if a ferrite antenna bar is broken, you can glue it back together and it will work fine. I've only read that, haven't tried it yet that I can remember.

You can even wind your own open air loop on cardboard, it could be even better, still more capture area. Older radios still need lots of turns to get the hundreds of microhenries like a ferrite loop has, while newer loops for newer and DSP tuners are smaller, I have a plastic one that's 14 turns on a 8 inch loom, just a magnetic pickup loop that's untuned apparently.
