When you buy MFJ PRODUCTS from an Authorized MFJ Dealer like JMR Sales or from MFJ they offer a one year unconditional warranty called the "NO MATTER WHAT" warranty. MFJ will replace or repair a customer's MFJ unit (at MFJ's option) for one complete year. A technical help support line is also offered toll-free for customers needing help or advice with a ham radio project. This applies to MFJ products only !! You must have your receipt to take advantage of this warranty.
