8. Power and Frequency measurement of
MF/HF Radiotelephone
MF/HF DSC signal is not transmitted by pressing a PTT switch, because of its emission
mode of F1B (J2B). Tone signals (1700Hz +
85Hz) must be input to the radiotelephone.
To measure the output power of DSC signal, follow the below.
The radiotelephone must be set to the frequency to measured and to F1B (J2B/TLX).
1. Pressing [#/SETUP] key reveals “Setup menu” screen. Select TEST and press [ENT]
key. Then, the following “Test function” screen appears.
To execute the test function, cancel “PROTECTION”. Enter “652111” from the
numeric keys.
2. Selecting TONE and pressing [ENT] key reveals a submenu.
Choose MARK or SPACE on the submenu, and turn the signal “ON” by pressing
[ENT] key. For example, choose “MARK”.
3. Transmit power by turn ON the handset PTT switch of DSC-60, and measure the
frequency and power.
4. To measure other frequencies, turn OFF the handset PTT switch and change the
frequency of MF/HF radiotelephone. Repeat steps 3 and 4.
5. After the completion of the measurements, turn off power for DSC-60.
