D 104 mike cord.

[Knightt150]

 Dose anyone know where I can purchase a new (well shielded) mike cord for my D104. The one I have is not shielded at all, it works well on the lower freqs  but not on the 10 meter band.

2 wire, 3 wire, 4 wire??

Try your local musical instrument store.

Thanks Pete: There no musical store close to where I live you would think someone makes mike cords.

I will keep looking maybe someone will come up with one there is a lot of D104's out there.

There are numerous places where you can buy bulk shielded cable, generally 100 or more feet, with single or multiple wires, and shielded.

If you're just looking for 1 wire shielded cable, find a old phono-type cable (phono plug to phono plug). Chop off the  plugs and you have a cable. Home Depot, Lowes, Best Buy, Radio Shack all sell these types of cables for under $10.

If I am not mistaken several places sell mic cord furnished by Bob Heil.  Check with one of the dealers that carry his stuff.  I believe it will be what you want, but don't take that to the bank, ask them before purchasing.

Heil used to advertise the cables... I looked at the website & couldn't find them.  Call 'em!

It's not a cable, it's....."Heilwire"!

Use a minimum 3 wire BRAIDED cable for mic hi, gnd, PTT and shield.  Dont use the shield to carry any current.  Best for RF to have a high percentage of shielding.

The cable you have may use twisted pair which can work quite well.

Ebay or a musical supply house as noted.

A quick check on e-bay for coiled microphone cable produced dozens of choices....some less than ten bucks with free shipping.Good Luck

If the D-104 is mounted on PTT stand as shown below a coiled cord from some old CB mike would work fine. Most of them have a shield and 4 or 5 additional conductors.



If the D-104 is just mounted on a non-PTT stand, a coiled cord probably would look ugly to some. In this case, a non-coiled cable with a shield and one or two conductors are needed. See picture below; D-104 2nd from left.

Is there a specific part number for the stand side of the D104 jack?

I have a few,  would like to build an adapter to XLR,  but wasn't sure what,  if anything,  the common part number would be.

Thanks in advance.

IIRC, the practice in broadcasting was to ground the shield at one end only. Is that still current?

If you want a straight cable, have you considered making your own? I needed a 6 ft XLR cable. Took one "twisted pair" from a scrap piece of ethernet cable. I used the center center conductor from RG-58 or RG-8X to pull it through the coax cable. I also used the same technique to pull 2 conductors + a thin shielded audio cable through some RG-8X. The end result was a double shielded cable made from a scrap piece of coax. Works fine - no noise or RF problems.

I use Belden 8412.  Extremely well shielded with a black and white conductors.  Used a lot in broadcasting.  Nice rubber covered cable with good flexibility.
