Radio shack Multivoltmeter 22-820 read out is OF and I do not know how to interpret it.
I don't know, maybe it is faulty or maybe it is telling you what you are trying to measure can't be measured on that range. I suggest you learn more by measuring a few known values to see what happens...
I have a Radio Shack multimeter and it was a complete waste of space from day 1 and no better after it had been "repaired" by the Tandy boffins. The readings vary wildly between summer and winter, often only half the display works and sometimes it doesn't work at all until it has been switched on for a while.

Need a schematic for a victrola radio model vta 750
The fashion for nostalgia radio with a modern sound has brought about a clutch of models from only a few manufacturers.
I have only encountered one such that was basically an in-house cabinet with bought in internals, the quality of which was probably reflected in the price and as this was from the lower price bracket the internals were from different sources and badly matched.
I know of no reason to assume other models would be substantially different because although popular they haven't sold in the high numbers that would justify purpose built internals and so the chances are an experienced audio engineer would probably recognise the circuit board as being from a popular hi-fi and be able to provide you with details.

These radios are great but why put talkback on a radio when itll only work on am..we use fm mainly in the uk..is there anyway of modding it so itll work on fm please
The short answer is no -- the difference between AM and FM is too great though some CB radios were made dual mode, like the President Veep I used to own.
Some CBs that found the way into Britain were powerful sidebanders that offered similar capabilities to unlicensed CB-ers to that official radio hams had to sit exams to enjoy. Some radio hams found it cheaper to have those top-line CBs modified for use on the 11 metre amateur band.
It would be no help to you to obtain a standard FM CB as when the UK was forced to legalise CB radio under the Treaty of Rome, they legalised it at a different frequency as the American frequency was already allocated to radio control, bleepers and other things. Special CB sets were manufactured for the UK market.

Motorola D700 (Ex Dolphin Tetra) Radio
HI.... yes ....it is possible to program them in DMO, this is done in the RSS,.... so I am advised directly from inside Motorola .... but a copy of the RSS is just not available.... ... if fact Motorola seems to officially deny the D700 ever existed ... good luck in finding a solution.
