I have made this mod, and I have the following suggestions: (a) you can get a "map" of the board via FAX or snail mail from Alinco -- this helps a LOT (it's impossible to read component labels) -- Alinco is in Torrance Calif, in the phone directory. (b) Throw away C40, it is impossible for a mere mortal to do what they are suggesting. Replace that SMT C40 with an axial .01uf cap (non-polarized, anything kind you want, I used a tant.) and some insulation tubing over the leads (it needs to stretch 2 inches across the bottom of the pcb. Alinco claims this mod makes 1200bps unusable, untrue, I use my modded 1200 on both 1200 and 9600 bps without noticable degredation of performance. Regards, Paul
