I have a JR xr3 FM ! had it for 9 years, I can buy rx's for it for about $25 in discontinued bins at run down LHS's, has all the epas, 3 channels and a 4 model memory baby! and you all run synthesized channel spread spectrum processing or the like now, so I can use my crystals and you bail off my channel lol.. We will see how it works with the MMM and 6s, may have to join the new century
