as green, yellow or red. After 10 seconds go up or down for 100 Hz and try it
again for 10 seconds, so you get a good average You try to get it green or at
least yellow. When you are done, go to another reflector and connect. Then
pus the Echo button on the right of the reflector number. Talk a few seconds
and the release the PTT. Your transmission will be played back from the
reflector and you can hear how you sound to others.
If your frequency setup was right you should have good audio and you are
done.
TX buffer size:
Before being transmitted through the built-in 70 cm/ 2 m transceiver the
signal is being buffered.
You will not need buffers or only a small buffer, if you have a stable and fast
internet connection
However, if you use mobile networks (H+, Edge, LTE etc), drop outs in the
data stream can be substantial. In this case you pick buffer sizes of 1 or 1.5
seconds. This will delay the transmission a little but will close the holes and
thus eliminate many interruptions.
Remote Control:
The DV4mini can also be controlled additionally by another computer.
Computer 1:
This is where the DV4mini USB stick is plugged in. Start the program
“dv_serial” in console mode.
Computer 2:
Start dv4mini.exe - the control panel software. In order to find computer 1 its
IP address needs to be entered in the field “distant
DV4mini IP/URL”
and you
activate
Remote Control on/off.
Now computer 2 can control computer 1. You will get all displays and full
control over all settings as if you were sitting in front of computer 1.
