Transmitter Alignment


If you did the receiver alignment, above, you may find that little or no
transmit adjustment is required on most bands.

Set the POWER control for 2.0 watts.

Switch to 80 meters and set the VFO for about 3750 kHz (mid-

band).

Enter tune mode and adjust L3 and L4 for maximum power as

indicated on the internal wattmeter. (Use a more sensitive analog
instrument if available.) Limit tune-up time to 5 or 10 seconds.

i

Since some inductors are shared between two bands, you must

always align the remaining bands in the order indicated. Always use
this procedure if you re-align the filters later.

Switch to 20 meters (14100 kHz). Set C21 and C23 to their mid-

points. Adjust L8 and L9 for maximum power output. (This step pre-
sets C21, C23, L8, and L9 before final adjustment in the next two
steps.)

Switch to 30 meters (10100 kHz) and adjust L8 and L9 for

maximum power output.

Switch to 20 meters (14100 kHz) and adjust C21 and C23 for

maximum power output.

Switch to 15 meters (21100 kHz) and adjust L10 and L11 for

maximum power output.

Switch to 17 meters (18100 kHz) and adjust C32 and C34 for

maximum power output.

Switch to 10 meters (28200 kHz) and adjust L12 and L13 for

maximum power output.

Switch to 12 meters (24900 kHz) and adjust C44 and C46 for

maximum power output.

This completes transmitter alignment.
