10. FWD
Output power indication. Used for tuning the Linear. The indication calibrated
for 50 ohm aerial impedance.
At other values the accuracy may be +- 10%.
11. REV
Will indicate the relative reflected power on the right side meter. Helps to check
the aerial.
12. Ig2
The concerning grid current can be checked (max 50mA
13. STBY
The PA can be driven only if this button is on OPR, otherwise the TCVR power
by-passes the PA. In case the overload protection is active, release the switch
and push it again.
14. PLATE meter
Indicates always the anode current of the PA. The green mark is the limit for the
base current, while the red shows the maximum allowable current.
15. POWER meter
Multifunctional meter. Forward or reflected power, anode voltage or grid
current indications can be selected.
16. TUNE knob
Tuning knob of the anode cavity. Use for tuning the PA.
