    Hmmm... I thought I knew that larger gauge wire had higher inductance...

    Odd... in audio speaker cables, when you start to get thicker than 12ga the inductance starts to rise and
    the HF response starts to droop. Which is why "jumper cables" or "welding cables" are not recommended
    for speakers that run into the higher freqs.

    I'll look at ur link.

    I would like to see the speak cable data....
    That goes against the formula for inductance.

    Thanks Sue....I was out of pocket the last day or so and couldn't respond to the follow-on questions.. BW

    I'd like to see this data also. Note...there's a difference between solid wire and multistrand wire conductor of the same equivalent gauge for an AC type signal/circuit. Depending on the weave or lay type of the multistrand conductor 'bundle', the fundamental conductor parameters can be different. You also need to consider the operational frequency range of interest and any 'sneak' paths for unwanted currents.....but now I'm being a 'purist'... BW

    Hello All,

    I am back from the Xenia Hamvention. Bottom line:

    I had a great time and it will take a week to clean the mud from the outside and inside of my truck. The flea market was brimming with treasures looking for a new home and I have never seen so many vendors at Hamvention before. I sold 2/3 of the stuff that I brought with me brought home a few things that I didn't know that I couldn't live without.

    Now it is time to finish this project up.
