The K-PO NM-532 P4 is wired for Standard 4 Pin Cobra/Uniden Radios.


These radios need the wire connected on Pin #4 for sound to come out of the radio's speaker. If you unplug the microphone on a radio like this, you will not have sound out of your speaker.

    Our Policy

    Returns and Refunds are generally not offered by Scott's Radios. I operate a small business and do not have a return policy like some giant online retailers.

    If a return must be made, a 50% restocking fee will apply to the total purchase price.

    I do unbox and test on camera all products returned.

    Please be sure what you're ordering is exactly what you're wanting to avoid the restocking fee!

    I will not ship, in good faith, a radio that is found to be defective during my testing.

    USA Based 10-Meter Radios from Stryker, President Electronics USA, Connex, General Lee, Ranger, and Galaxy are strictly Factory Warranty Only. Customers will need to ship their radio to the designated Warranty Repair Facility.  Shipping cost is normally the responsibility of the radio owner.  

    Shipping back is normally paid by the Warranty Repair Center.

    Scott's Radios LLC will not, in good faith, modify any 10 Meter Radio in a way that would cause damage and lead to a premature failure.

    Scott's Radios LLC does not offer refunds or accept any returns for any reason on the USA based 10-Meter Radios.

    Blown Driver/ Finals, Regulators, Protection Diodes, will be considered operator error and a repair will most likely be at the expense of the radio owner.

    10-Meter Radios from K-PO, CRT, Alinco, Superstar, and Anytone do not carry any after the sale warranty. This is not the choice of Scott's Radios LLC, but we do also accept this policy when buying these radios in bulk for resale.

    Scott's Radios LLC does provide a YouTube video for all New 10-Meter Radio Sales.

    Since these radios are more affordable, the customer must decide if paying more (in most cases) for a USA based 10-Meter Radio (With Warranty) is the best option for them.

    I do recommend all in the radio hobby invest in a quality Antenna Analyzer. Most radio failures are caused by an operator using a mismatched antenna system, or questionable linear amplifier setup.

    “Remember Your Antenna/Feed line” is the most important piece of any radio station.

    “Avoid the myth that power is the most important factor.”

    I'm are here to help in any way I can if an issue does arise.

    I want all of my customers to have years of enjoyment out of all of their radio equipment.
