HG-1 WR 80M AND 60M OPERATION
The HG-1WR is capable for 60m and 80m operation. Because of performance optimization circuit boards with
isolation jumpers are used to connect external the 60m and 80m resonators. These circuit boards are mounted
on each side of the case. See figure below.
These boards are identical. On these boards there is a solder jumper labeled 60/80M JUMPER JP1. See figure
below:
These jumpers isolate the banana jack inputs and must be bridged. For 60/80-meter operation create a solder
bridge on both boards. Heat the pads and apply sufficient solder to bridge the pads.
The Banana jacks are mounted on the top of the case and are water resistant. The external resonator can be
inserted approximately 2/3 into the jacks and will fit securely.
Tuning is done with the main resonating tuning capacitor as in 40-10-meter operation.
DIFFERENCES BETWEEN MANUAL AND REMOTE TUNING
When tuning manually the operator tunes for a peak receiver signal by rapidly turning a knob and listening for a
peak receive signal after which he then makes small adjustments to fine tune and to achieve the lowest SWR.
Because of AGC action, if you were to initially tune slowly, you might never notice the increased noise level
indicating a peak signal. Tuning with a remote controller is different. The operator sets the tuning rate and then
pushes either the up (red) or down (green) buttons to tune. Initially the tuning rate should be set fast to detect
a peak, after which the tuning rate is lowered to fine tune for best SWR. This takes a little practice at first. The
benefit is that your hand will not affect the tuning capacitor, and you can do this remotely without touching the
MLA itself.
