Motorola SABER, MX1000, Stornophone 7000, etc.
- under construction
SABER hand-held radios can be improved and enhanced in a number of ways.
Some of these modifications are described on this page.
|
Most Motorola SABER radios can be programmed for frequencies that are not
within their normal range, as long as these frequencies are not too far off.
This can be useful for making the radios suitable for HAM radio use.
The problem however, is that the outer limits of a frequency section (split)
are hard-coded in the RSS. A description on how to modify the RSS for
out-of-band programming can be found
here.

|
Submersible versions of the SABER, and possibly other versions as well,
have their built-in microphones covered with a piece of tape, in order
to protect it against water. Such a piece of tape often degrades
the speech quality. As amateur radios generally do not have to be
submersible, it might help to remove the tape.
In some cases it may be necessary to adjust the VCO modulation of
the radio using the RSS. If this doesn't help, the microphone
might be bad or the COPE board (i.e. the display and the controler of
a SABER II or III) might be faulty. Try whether an external microphone
produces a clear sound first.
If the external microphone is clear and the internal one stays mum,
try swapping the display board. This board carries the DTMF generator
that sits on the microphone line.

The channel selector of the international versions of the SABER,
such as the MX1000, has just 10 positions, rather than 12.
Furthermore, the range of the channel selector might have been limited
by means of a (mechanical) locking ring. The number of channels can be
increased by moving this ring to a different position, or by removing
it altogether.
If the locking ring is removed completely, the number of positions
of the channel selector of any SABER type is increased to 15.
With a bit of tweaking it is possible to use the extra positions,
but not for every zone.
A good description of how to tweak the radio's DCT file
can be found here
