MF/HF Radios
Set Number
As you may wish to test several radios under the same MMSI, each radio can be given its own
individual set number for recognition. Default number is 1. Press
“OK”
to confirm or press
↑ or ↓
to change to another number. Then, press
“OK”
and go to the test you wish to perform.
Receive DSC
In the Receive DSC test mode, the test box will receive the radio’s MMSI number and DSC data
transmitted, and at the same time measure the frequency of the transmission.
Connect the wire antenna supplied with the test box and use the setup below. The test box
antenna should be able to “see” the transmitter’s antenna.
Select
“Receive DSC”
and press
“OK”
. Then select whether the test box is going to receive
the call on one of the
“TFC”
channels or
“MF/HF”
distress channels. Press
“OK”
and select
frequency. Finally, press
“OK”
again and activate the transmitter.
The test box remains in receive mode until a DSC call is received. A press on the EXIT button
can interrupt the mode, provided that the test box has not started to receive a call, in which case
you have to wait for a few seconds. MMSI number, data and the MARK/SPACE frequencies are
presented in the display and stored in memory, provided that the checksum is OK.
Test results are displayed line by line. Press
↑ or ↓ to toggle between the lines.
If the MARK/SPACE frequencies do not appear on the LCD display, the signal is most likely
outside the limits 1770-1800 Hz / 1600-1630 Hz, or the signal was unstable during the header
or that the header was too short (less than 11 bit). If data are shown as 255, it's because they
were received in error.
