I have had many rci 2950 and rci2950dx,and got them from Copper un modded and untuned,i dont use them on 11mtrs,i use my Brownings for that.And i did get the e-chip or jumper...as people call it...I have also ran the rci5054 and also the 100 wtt 5054,and yes they also have the rci2950dx with the tone board from them and a small cost...73 de JW
