Shortwave Radio

Hi, I've got an ICOM 600 with the diodes clipped to open up all the ham bands (have a General Class). Though an old model, it works very well unless the engine is running. With the engine running and alternator going, I get massive RF interference. I'm sure there's a fix for this, but don't know it. And ideas would be appreciated.

Thanks,

Karl

I agree, chokes on the power leads, and make sure all connections are tight. Fidgety connections can also generate RF interference.

Okay thanks. So, just to be clear, I'll place these filters in the power leads (plural means both pos. and neg., right) and I can put them in the line just ahead of the radio itself?

Oh, and can you recommend a particular RF filter?

I'd go to a place that sells car audio, and see what they have in stock. I've seen simple snap together magnet assemblies that should suit your needs.

Since they are really rather simple devices, I wouldn't concern myself too much with brand name, but rather ease of installation (snaps on easily), and moisture tolerant (the snap on ones I'm thinking of are basically 2 magnets in a plastic housing).

These aren't magnets, but ferrite cores.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
