MB7000 256 channel 12.5KHz spacing

Combined UHF 99 channel talk-through system.
(Circa 1990 plus)
256 channel AM / FM VHF/UHF
1990ís boot mounted mobile system. One
of the much later sets based on the CM7000. which comes fitted with two CH650 99
channel portable sets (less batteries) transmitter-receiver units.
One is receive only on UHF 99 channels.
One is transmit only on UHF 99 channels.
And one Cleartone CM7000 boot mounted set VHF 143 Ė 156 MHz AM / FM
set. All this in one black crackle
finish enclosure boot mounted set, to give talk-through VHF-UHF and UHF-VHF. 2
metres Ė 70 cms.
The accompanying control boxes are very flash in red-green/red white with no
protruding knobs, all flush touch buttons. If
the control box to boot set lead is missing, a standard VGA monitor lead female
to male will work instead.
There are four EPROMís to change. One
in each portable set. Two in the
main set. I have not yet run the
sets on 2m & 70 cms yet as the EPROMís are not yet available.
The control boxes that stand vertically, not horizontally, work OK.
Beware! There are horizontal
control boxes (red-green coloured) but they had design faults, were unreliable
and were replaced with the vertical mount ones.
Cleartone CM7000 is just the two transmitter-receiver CH650 portables in one
boot mount case with grey push button control box for UHF talk-through only.
