Midland D-200, the radio becomes
digital!
D-200 is an analog/digital transceiver operating on the
446 MHz frequency.
It's an innovative equipment that allows to communicate
with two different communication protocols: DPMR446
and PMR446. The digital brings many advantages
and offers new important functionalities: first of all, the
quality of the communication is much clearer and this
allows you to hear limpid conversations at a greater
distance than the analog system. Another remarkable
feature is the audio digital processing that considerably
reduces the sensitivity to noises, such as the opening of
the squelch or interferences.
Furthermore, the digital band is really new and therefore
it is not so overcrowded like the standard analog band
but more accessible.
Digital radios offer a range of innovative features: let's
start for example from the number of channels that is
double – 16 – than a standard PMR446; digital radios
also give the possibility to make individual and group
calls.
In particular, D-200 is equipped with 3 customizable
buttons with which you can make 3 different types of
calls: standard, individual and group calls.
Another function to emphasize is the powerful digital
scrambler that makes communications impossible to
be intercepted by prying ears and ensures maximum
privacy in conversations. The scrambler can be enabled/
disabled through the optional programming software.

Main controls and parts of the
radio
1. Antenna
2. Encoder: rotate clockwise or counter-clockwise
to select the desired channel.
In PMR446 channels the radio will confirm the
selection with a beep.
DPMR446:
in DPMR446 channels no beep will
be heard. This sound message can be disabled
through the programming software.
3. Power/volume knob- turn clockwise to power
on and increase the volume level. Turn counter-
clockwise to decrease the volume level and
power off.
4. Speaker
5. Built-in microphone
6. Led indicator: RED: TX; GREEN: RX.
7. PTT: press this button to transmit and release it
to receive.
DPMR446: in DPMR446 channels the pressure
of the PTT button corresponds to the group call.
By means of the programming software, you can
match the pressure of the PTT to the sending of
the standard call (call to All).
8. Function key 1: Hold down this button to
activate the Monitor function (PMR446 channels).
DPMR446: in DPMR446 channels the pressure
of this key enables the single call sending. To
transmit, keep it pressed.
9. Function key 2: not programmed by default
(PMR446 channels).DPMR446: in DPMR446
channels if you hold down this key, D-200 will
send a call to the group you belong to (group
call).
10. External Speaker/Mic Jack- allows the
connection with external devices such as
headsets, microphones.
Transmission
To communicate, all radios in your group must be set
to the same channel.
DPMR446: we underline that in the digital protocol
you can communicate only with radios having the
same vocoder (voice encoder).
The vocoder is an electronic system inside the radio
that is able to decode audio signals. D-200 uses AMBE
2C vocoder.
