Final notice: I decided to build a few
speed pulse generators for others on this forum but both batches sold out quickly. So I got my hands on a huge parts stockpile and I am building 8 units this weekend but 3 of those were already sold even before I finished the assembly. So if any of you still want to enable all NAV functions all the time via the speed pulse generator and you can't or don't want to go through the hassle to make one of these devices for yourself, then you can PM me and I will give you one of the units I am building until my stock runs out. I don't plan to build another batch any time soon - too much else to do right now including the ever-growing honey-do list which has suffered while I solder away in the computer room each night on these circuits...
