5.2.3 ADMINISTRATOR (Level 2)
NOTE ! This is for information ONLY.
Level 2 access shall only be available for administrator in connection with
configuration of the Transmitter during Commissioning
When logged in to the PC as “Administrator” you may, in addition to “General user” as
specified above, have full access and ability to configure and make adjustment and
monitoring of the Transmitter such as :
Setting Carrier frequency
Setting RF power output
Setting Modulation type - Morse, Audio or MSK (option)
Setting Modulation depth
Setting Morse tone frequency and Morse sequence (ID)
Setting Keying rate
Setting of four (4) different Morse messages
Selection of type of timer and setting of time
RESET of Main or Reserve Transmitter, if failed (Alarm)
Setting User name and Pass words and selection of mode for Reserve Transmitter
Reading event log that records all system events, such as restart, parameter changes and
error events.
(The JTM-30C has a built-in non-volatile memory sufficient for storage of the entire transmitter
configuration, and enabling stand-alone un-attended operation. Saving the configuration in
solid-state memory is controlled via the PC interface).
5.3 Color and number information on the PC
Readings in the PC windows.
The numbers in the windows are not absolute values, but approx. information only for
quick status overview.
5.3.1 Power (WPEP)
The “Power (WPEP)” window is an indication to check that the Transmitter is
generating RF output to the Antenna. When the Transmitter is switched ON and under
normal condition the background of the window is GREEN, and will be GREEN as log
at the RF Power output is 70% or higher than programmed “RF pow. (%)”.
E.g. if “RF pow. (%)” is configured to 50% and the number in the “Power (WPEP)”
window is above approx. 35 the background is GREEN, but the background will turn to
YELLOW if the number in this window is below approx. 35.
The equipment is still operational if the background is YELLOW, but RF output is
reduced due to poor Antenna tuning and/or due to poor cleaning of the Antenna
Insulators.

5.3.2 Current /A)
This window shoes the DC current supplied to the Transmitter.
Under normal condition the window is white, and will be white as log at the DC current
is less than 15 Amp. If the DC current is higher than 15 Amps the background turns
RED indicating excessed DC current indicating that the DC drain current to the
Transmitter is too high.
5.3.3 Power Amplifier Temp (C)
This window shoes the temperature (Co) at the Output RF Transistors
When transmitter is switched ON the background of the window is white and will
indicate the temperature on the Output Transistors. During operation the temperature
will increase, but normally not exceed 65 Co.
If the temperature for some reason should increase above 80 Co the background
becomes RED.
The RF Output Amplifier will operate normally up to 90 Co. If exceeding 90 Co the RF
Amplifier will shut-down. When after the RF Amplifier has cooled down to temperature
below70 Co the RF Amplifier will operate normally again.
5.3.4 Antenna VSWR
This window is inserted to have control over the impedance matching and Antenna
Tuning. During ideal conditions the VSWR should show less than 1,5.
The Transmitter is considered operating correctly as long as the VSWR shows below 2,5.
After finishing fine tuning of the Antenna Tuning Coil adjust the Impedance matching
to minimum VSWR.
If the VSWR figures exceed approx. 3,5 the background first turns YELLOW, which is
an indication the Antenna Tuning and/or Impedance matching is not optimal.
The equipment is still operational if the background is YELLOW, but RF output may be
reduced due to poor Antenna tuning and/or due to poor cleaning of the Antenna
Insulators.
If the figure exceeds approx. 5,0 it is an indication the equipment then the
Antenna Tuning is not correct and/or problem with the Antenna or Antenna
Insulators.
5.3.5 Ambient Temp (C)
This window shows the temperature (Co) at the Exciter (temperature inside Transmitter
cabinet).
5.4 Operation from PC locally or via Internet (Single Site Mode)
When starting the PC program
This in order to avoid possible unwanted change of configuration, which was set
during commissioning of the equipment, it is of importance to dedicate a separate
User Name for the OPERATOR.
