Mods, feel free to move this if I'm in the wrong place.
We have an old Zetron Model 10 encoder that we're trying to get to work again. Does anyone happen to have a book for this thing? (we can't find it)
I can get it to tone out single tone pairs (I think it's set for a standard 100 call group) (e.g. 22 gives a long 630Hz tone), but I need more than those 10 tones... (or a bunch of new reeds for our old pagers...)
Those old Zetron encoders (100 call) were limited to a single code group. When you ordered them you had to specify a code group or the X group (custom). If you want to change groups, Zetron will then have to blow you a new prom, but alas you will be limited to one group only again.
