I need a 21 MHZ module and a 24 MHZ module for my Ten Tec Scout. I have a SPARE 7 MHZ module that I would like to trade for a 21 MHZ module. I will buy a module or trade the 7 MHZ module PLUS some BOOT to get the 21 MHZ module. Does anyone have a 24 MHZ module to sell ? Thanks for reading and please email me directly. 73, John, K5PGW
