Monitoring 146.520 shirt. This is our 2m national simplex calling frequency t-shirt. A national calling frequency in the USA is a radio frequency that is widely accepted and understood to be a place to start communicating with other hams.
The 2m national simplex calling frequency is sort of a universal (within the USA) place to make contact when you are not sure where to start. It is particularly useful when traveling to a new area where you don’t know the repeater frequencies, offsets and access tones. It’s also a great place to get assistance in an urgent situation.
The t-shirt is a Jerzees shirt, 50% cotton, 50% polyester which means it's machine washable and won't shrink. It's medium weight at 5.6oz, so its not flimsy but also not too heavy. Standard unisex t-shirt design, so it makes a great gift. Please see the sizing chart to determine your size.
The transfer is permanent, but we recommend turning the shirt inside out for machine washing to prolong the life of the shirt.
