Maybe Ten Tec has the documentation. While some old manuals are on their
download area, they don't have everything there. A inquiry may bring you
a copy or maybe Ten Tec will post it on the download area.
The VO1 capacitor rotates only 180 degrees, so if the calibration marks
cover only half of the dial area, then it was meant to mount on the
capacitor shaft. Also, look at the dial to see if it has a bushing and
setscrew to mount it to the capacitor shaft. If, instead, it has two
small holes on either side of the center hole, and the calibration scale
covers most of the dial area, then it was probably meant to mount on one
of those 6:1 vernier drives. I doubt that Ten Tec intended the MR1 to be
used with a dial cord. That would introduce too many variables and
complexities.

Hi Bob,
Scanning the dial is a great idea --- I should have thought of that ;-)
I'll do just that, get some dimensions, and a couple of JPG photographs to go
with it. Should be able do that sometime this (cold) weekend. Perhaps someone
can assist with posting them where appropriate.
I still don't have whatever passed for documentation for the MR-1. I was hoping
it might shed some light on how to mechanically drive the dial (that is, does
it go on the VF-1 capacitor shaft, or is it string driven with a pulley like
the PM-1?)
Tks!

I bought a Ten Tec TG-38 aluminum box to package mine in. I plan to mount the
modules to the bottom of the box with threaded spacers.
The Ten Tec wiki says that the MR-1 was intended for bread board mounting, but
I'd rather put it in a box of some sort. Just use your imagination. Consider a
large wood file card box, wood gift box, surplus ammo box Pelican case,
sportsman's dry box, etc. If you do breadboard it, as in the days of old, you
will still have to mount the boards on spacers and fabricate brackets to hold
the variable capacitors and switches. You will also need a vernier dial drive
because the VO1 tuning capacitor does not have a reduction gear, at least mine
doesn't.
If you or anyone else has the dail, can you scan it and e-mail it to me. It
would save me the trouble of making my own dial scale.
Thanks and 73,

Last week I happened into the round frequency dial disc Ten-Tec had sold with
their MR-1 kit in ~1969-1970. Now I'd like to assemble the four (VFO, TX, MIX,
AA) modules I've gathered over the years into a (hopefully functional) MR-1.
The hitch is I don't know what an assembled MR-1 looks like (presumably modules
on a piece of wood.) Was there a sketch or drawing published by Ten-Tec showing
how it would look? Google image search didn't turn up anything involving the
four modules and the round frequency dial part.
Very tks,
