4.1 Connect your 4 and 6m TCVR to the Linear inputs using a short, 50 Ohm coaxial cable.
4.2 Connect your foot switch to the PTT RCA socket(red) on the rear panel , using a screened
cable.
Low current and voltage input, connect it to PC serial port PTT output circuit on case DIGI
modes.
4.3 Connect your aerial (4 or 6m)to the OUT socket of the Linear. VSWR must be better than 1:2.
4.4 Using a flexible cable at least 6mm
grounding point of the transceiver.
4.5 Connect the power cord to the mains and switch on the equipment. The ON led glows and the
WAIT led start blinking for a period of abt. 180 sec, during the heating period.
The readiness of the Linear is indicated by the OPR LED. If the PA was out of use for a longer
period (2- 3 month), it would be advisable to keep the PA heated without driving for a few
hours.
4.6 When the OPR LED is light push on the OPR switch. The PA is ready to work.Select the band (
4 or 6m) with the band switch.
4.7 Using the tuning mode of the TCVR (CW) give driving power to reach 200-400 mA indication on
the Ip bargraph. Tune for maximal output power with Plate and Load knobs. Increase the
driving power until maximum anode current, than carry out fine tuning using knobs. You can
indicate the reflected power on RFL LED bargraph.
REMEMBER THIS AMPLIFIER DOES NOT REQUIRE MUCH DRIVE POWER. SO START WITH
LOW DRIVE POWER, AND NEVER USE MORE THAN 100W INPUT POWER!
4.8 Check the grid current. Reduce the driving power or make fine tuning in case the grid current
would exceed THE SPECIFIED VALUE!
4.9 During SSB transmission the peak power of the TCVR may exceed the allowed maximum
driving power of the transceiver! Use The POWER knob on the TCVR in this case.
