A number of years ago I picked up a TAC-310SX at a hamfest and spent literally days figuring out the programming scheme. I wrote a spreadsheet program that would calculate the eprom data for both VHF and UHF units and have since that time used it with half a dozen radios. If and when I escape the mid-Atlantic blizzard and get home, I can send you the spreadsheet or do the calculation for you. If you want me to burn the eproms, I can do that for you as well.
