Страница 3: ...o a bypass condition This overload condition can be reset by momentarily putting the STBY OPR switch in the STBY position Caution This amplifier must be disconnected from the power mains before removing the cover See the warning on page 10 TECHNICAL SPECIFICATIONS AL 1500 Input Circuit type Pi network slug tuned coils Maximum VSWR at resonance 1 3 1 Minimum 2 1 VSWR bandwidth 20 of center frequenc...

Страница 4: ...it board mounted on the front panel side of the filter capacitor board that provides time delay to insure the cathode of the 3CX1500A7 8877 has reached proper operating temperature before high voltage and RF drive power can be applied This board also samples the peak grid current and removes drive if the grid current is excessive The timer portion if this circuit board uses IC1A as a com parator t...

Страница 5: ...RIODIC MAINTENANCE The high voltage present on the plate choke and air variable capacitors attracts dust and dirt out of the air stream It is particularly important that the high voltage areas at the bottom of the plate choke and the insulators on the air variable capacitors be dust free These areas should be inspected every few months if the amplifier is operated in a dusty environment Unplug the...

Страница 6: ...0V operation in Japan Caution Do not use the 220V wiring unless the line voltage is always below 220 VAC The Standard USA voltage is 240 VAC not 220 For 220V operation see Fig 3 follow the first three steps above then follow the steps below 1 Slide the RED boot back on the BRN WHT wire 2 Clip the terminal connector off the wire and slide the RED boot off 3 Remove the restraint from the GRN wire an...

Страница 8: ...ors 3 Use shielded audio type cable with standard male phono plugs to connect to the RELAY jack on the AL 1500 This jack has positive 12V DC open circuit and supplies 100mA of current when pulled to ground 4 Connect a short ground lead from a good earth and RF ground to the GND terminal 5 The 12V connection on the rear panel provides 12V DC at 100 mA maximum to operate external dial lamps or acces...

Страница 9: ...rupt electrical continuity to the water supply line Install a jumper around any insulating water connections you may find Use heavy copper wire and pipe clamps It is best to ground all equipment to one point at the operating position and then ground this point as described above TUNING INSTRUCTIONS Proper tuning of a grounded grid linear amplifier is best accomplished with an understanding of what...

Страница 10: ... It should be 75 mA Place the CW SSB switch in the SSB position Plate current should now read 250 mA Return the CW SSB switch to the CW position Note The no drive currents will vary up to 25 due to component and line voltage tolerences 8 Apply only enough drive to indicate a grid current of 50 mA or an Ip of no more than 500mA Tune the PLATE control for maximum output power or grid current It is n...

Страница 11: ...OCEDURE 1 Place the SSB CW switch in the SSB position 2 Adjust the exciter gain control to permit voice peaks to reach the same value the peak output meter read on CW when fully loaded The plate and grid currents should remain well below 50 of the CW values during normal modulation SSTV FM RTTY PACKET AMTOR The plate current should be limited to 800 mA maximum The grid current should be limited to...
