Hello Folks, I need some info. I have a nice HT 32B rig and I know there is an SX 101A receiver made to match it with the knobs with what I call finger flats on the them like rig, or the HT44 / SX117 series gear....I would like to know the series number such as Mk 1,2 3 etc.... I have an HQ 180C that I would trade on one.... Thanks for reading.... 73, Sam
