Ameritron 811h 10 Meter Mod

Insert Gt Keygen Software. Also for sake is the ALS-1300X which includes a 10/12 meter mod kit. Ameritron Al-811 linear amplifier gives you plenty power to bust thru QRM.

• HF POWER LINEAR AMPLIFIER INSTRUCTION MANUAL The Ameritron AL-811H is an economical 800 watt PEP output linear amplifier that operates reliably from 160 through15 meters. The AL- 811H uses four 811A tubes in a class AB2 grounded grid circuit. Heavy duty power supply and RF components provide long service for components. • NOTE: Fuses supplied are for 120/110/100V operation (Models AL-811H/HY). If you are rewiring the AL-811H for 240/230/220V operation, you must use 8 ampere fuses. The AL-811HX export model is pre-wired for 240V operation and is supplied with 8 ampere fuses.

• The AL-811H is a grounded grid linear amplifier developed by Frequency Coverage Ameritron using low cost 811A power triodes. It operates in Domestic model (AL-811H): 160, 80, 40, 30, 20, 17 and 15 class AB2 for SSB and CW. • The interlock switch stays closed to allow AC line voltage to ALC line disconnected. The ALC line can then be connected reach the power transformer as long as the AL-811H's top cover and the ALC control on the amplifier can be adjusted to a point is in place. • The exhaust air flow is over 20 CFM.

Do not 'assist' the appropriate setting indicated by the chart below. Note: the AL- air flow unless the fan exceeds the AL-811H fan CFM by a 811H transformer allows operation on 100V line voltage in factor of 2:1. • Connect the RF output of the transmitter or transceiver to Connect the shortest possible ground lead from a good earth the RF IN connector on the rear of the AL-811H with 50 ground to the GND terminal. The best leads are solid ohm coax.

• It should be 75mA. Instructions on page 4 for wiring details. NOTE: The no drive current will vary up to 25% due to Set the AL-811H front panel switches as follows: component and line voltage tolerances. During POWER/OFF-ON to OFF tune up, limit Key to 7 seconds.

• Ameritron offers a high Ameritron for details on the QSK-5. The AL-811H will operate with full output on all WARC bands except 24.5 MHz The AL-811HX/HY will operate with full output on all WARC bands STANDARD FREQUENCY COVERAGE. • PERIODIC MAINTENANCE The high voltage present on the plate choke and air variable Remove the cover and connect a jumper wire from ground to the capacitors attract dust and dirt out of the air stream. It is anode connection of the tubes.

Particularly important that the high voltage areas at the bottom NOTE: This is a safety wire that must be installed when of the of the plate choke and the insulator on the air variable. • AL-811H SCHEMATIC Power supply shown wired for 120V operation *. • AL-811H INPUT CHART BAND C3 (pF) C4 (pF) 28.75T (405-1287) 1300 (250-1130E) 100 (250-0100) 23.75T (405-1237) 500 (250-0500) 750 (250-0750) 13.75T (405-1137) 500 (250-0500) 120 (250-0120) 20/30 330 (250-0330) 9.75T (405-1097) 270 (250-0270) 15/17 120 (250-0120) 6.75T (405-1067) 150 (250-0150) • PARTS LIST (ctd.)
