I want to know if theres a setting for the up and down buttons how they function on the MD-1 Microphone when using it on my FT-990 as far as using the memory channels. On both of my FT-840 radios when memory is selected I can use the up down channel buttons to scan through memory channels but on my FT-990 when I push the up down buttons it just changes frequencies not the whole saved channel. My FT-840's I can click through all 100 memories its nice to be able to do but that 990 its like turning the VFO Im thinking if my 840 can do it there has to be a way the 990 can be setup to do it also any help would be appreciated....Thanks Tony
