I will need to make some audio cables for the new K3 for the LP-PAN to the audio box, and also to the other soundcard.
I think I read somewhere in one of the K3 manuals that it is best to use small coax, as it has better shielding. Makes sense to me, and LMR100 seems to fit the bill, but at $0.64 per foot, I wonder what else is available? Not cheesy RS audio cable, but decent coax? Considering the length involved, the LMR100 isn't going to break the bank. :>) |

The only important thing about unbalanced audio cable is that it the shield has low DC resistance. The calls for a decent copper braid shield. Mini coax like RG176 works fine. So does ordinary RG58. But remember, I said COPPER BRAID, NOT ALUMINUM FOIL! AND -- resistance isn't even that important if you follow the simple instructions on bonding all the chassis together with short pieces of copper. I use either the braid stripped from coax (equivalent to #12 - #10) or an equivalent piece of THHN (house wire). To understand all this, see the Ham Interfacing Power Point and the chapter on solving problems in the shack in my RFI Tutorial. http://audiosystemsgroup.com/publish.htm 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Bob:
If you go to www.cablesondemand.com, they have all kinds of Amphenol cables for sale. I've only ordered from them once (absolutely no affiliation), but the cables I bought seemed very high quality and reasonably priced. They have all kinds of cable, not just audio, but coax and computer cables as well. 73's, John AA0VE Bob - W0GI wrote: > I will need to make some audio cables for the new K3 for the LP-PAN to the > audio box, and also to the other soundcard. > > I think I read somewhere in one of the K3 manuals that it is best to use > small coax, as it has better shielding. > > Makes sense to me, and LMR100 seems to fit the bill, but at $0.64 per foot, > I wonder what else is available? > > Not cheesy RS audio cable, but decent coax? > > Considering the length involved, the LMR100 isn't going to break the bank. > :>) > Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
