Tuning with the HG-2 Controller (HG-1 Remote Tuner Retrofit)
1.
If possible, turn the receiver AGC off or set it to slow; bypass any external or automatic antenna
tuner and set the mode to SSB (it’s has the loudest background noise).
2.
Turn the HG-1 Remote Controller to SBY (on) and set the Rate
control to Max.
3.
Note: Applies to HG-1 Remote only. There are no limit
switches on the Remote tuner. The HG-2 Controller samples
the motor current. When the capacitor reaches its CW or
CCW limits the limit light turns bright indicating you have
reached the end of capacitor rotation limits, thus alerting the
operator to change tuning directions.
4.
Using the red Up or green Down buttons, tune for a peak
receive signal (use your ears or the S meter). The maximum
peak will be brief, but obvious. You may have to momentarily
push the Up or Down buttons to get close. (The red Stall LED
lights if either the lower or upper limits are reached
–
slight
flickering is normal).
5.
Once you receive an obvious peak signal, reduce the Rate control and alternately make small
adjustments using the Up or Down buttons for the strongest peak signal.
6.
Note, when checking SWR, transmit a low power carrier. You should be able to achieve an SWR of
2:1 or better. In rare cases, you may want to use an external tuner to touch up the SWR.
7.
Set the receiver to the desired mode and turn the HG-2 Remote Controller off.
HG-1 WR REMOTE LOOP TUNED MLA
Outdoor deployable
This remote is designed for harsher outdoor and fixed installations. It is a durable, easy-to-use, remote tuner
upgrade to your existing HG-1 MLA using its radiation and induction loops and mast. It features end-of-cap
travel limit switches for long life. It uses the new HG-2 universal controller. To maximize reliability found in the
harsher environmental conditions outdoors, this remote
tuner uses a lower RPM motor and no reduction gear. For
this reason, there is a shallow learning curve to get used
to remote tuning. SWR is as low as the manually tuned
HD-1 which uses the identical tuning capacitor. We
recommend, for convenient and quick tuning to lowest
SWR, using an auto tuner, such as those found in the KX2
or similar transceivers.

Tuner)
1.
Make sure the HG-1 MLA is placed in an
obstruction free area.
