    I am new to the QRZ forums.

    I was trying to change the microphone connector (RJ 45) on my Radio Shack HTX-212, BUT I misplaced the old conector.
    I do not have the proper wire order (assignments, color).

    I may have to buy the wife a new radio if you can not help!

    Need help !

    No.

    I get a few newcomers to QRZ, that ask their questions directly to me via Private Message -- I do not answer these messages.

    Rather, I post their question in the QRZ Q&A forums where they belong.

    I believe that the Radio Shack HTX-212 was OEM manufactured by Kenwood.
    As I remember, it was based on the Kenwood TM 2x1 series of radios (221/231/241) -- of that period (mid-1990s).

    The Radio Shack used a 6-pin modular connector on this radio, while the Kenwood radios used the 8-pin Foster circular microphone connector.
    Manuals and part listing can be found on Radio Shack web site, under Support !

    CONSULT and READ the G4WPW Micorphone Connector web site for a PICTURE of 6-pin connector !

    6 pin modular connector

    pin 2 - BLACK (Ground for PTT and MIC)
    pin 5 - YELLOW (Microphone)
    pin 6 - RED (PTT)

    8DEY ... so Greg has 11,698 posts ... big deal since I would bet that 11697 of them have good informaton. Greg is one of the most helpful guys on this site. So is Steve, WB2WIK and Glen, K9STH. It is pretty obvious you have not followed Greg with his wealth of info.

    I have a RadioShack HTX242 and it has a 8 pin, not a 6 pin modular jack. All eight leads are used. I have sent RG4WPW corrected information to fix his website.
    Pinout follows:

    1 Tone
    2 Gnd (mic shield)
    3 Ck
    4 Con
    5 Mic
    6 PTT
    7 5V
    Data

    Forgot to mention.. you need to be careful about interpreting the pinout order. On the RadioShack, if you hold the new connector with the latch away from you so you are looking at the "flat side", with the connector pointed up (cable coming in from the bottom), pin 1 is on the left. Not everyone numbers them this way. I think this is consistent with the "Icom" numbering convention as listed on RG4WPW site.

    Pinout follows:

    1 Tone (yellow)
    2 Gnd (mic shield)
    3 Ck (black)
    4 Con (green)
    5 Mic (white - center conductor of shielded wire)
    6 PTT (orange)
    7 5V (brown)
    8 Data (pink or red)

    FYI: I'm in the process of replacing my connector as well. Be sure you get the right RJ45 (stranded version, or you will have intermittent connections) they come in both varieties.
