Combined UHF 99 channel talk-through system.
(Circa 1990 plus)
Cleartone MB7000
256 channel AM / FM VHF/UHF
mobile system.
1990’s 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 – 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 – 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 EPROM’s 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 EPROM’s 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.
