1) Make sure TuneMatic is powered up, and the motor is not in motion, or in Autotune, and wait for start-up
messages.
2) Press and hold (INIT) button for at least 3 seconds; TuneMatic will repeat the initialization process as
indicated in (2) above. Once you hear the Morse message; you can then release the INIT button.
NOTE- Reinitializing antenna does NOT erase any stored memories. To erase all memories, see section
(D- Factory Reset) below.
C-3 TESTING ANTENNA OPERATIONAL LIMITS:
You may manually tune the antenna, by using an external VSWR meter, or radio-provided internal VSWR
meter. This will give you a good indication as to the operational frequency range of the antenna, and will help
you determine the expected performance of the system. The make and model of the antenna, and its physical
properties, ground system, and overall installation will determine the usable operational range of the
TuneMatic. It is advisable to check the limits of the antenna system, so that you will know what to expect
during operation. Otherwise the TuneMatic may attempt to tune a frequency that is outside the operational
parameters of the system with little or no success, or not even tune properly.
Using the external VSWR meter, use low levels of RF power (10 watts in AM mode) so that you do not cause
interference on the air, or damage to radio and antenna. While adjusting the UP/DN buttons, check the
parameters of the system, by alternately moving the antenna, and spot-checking the VSWR, by keying the rig.
Start at the highest band , and work down to the lowest. This check will assure you that the system will tune
properly, and to what frequency range it will perform over.
NOTE: You can conduct these tests when TuneMatic is either initialized or not initialized. Remember: you
cannot use any of the automatic tuning or storing features until the antenna has first been initialized.
C-4 - MANUAL ANTENNA TUNING AND STORAGE:
Once you know the operational frequency limits, you can manually store frequencies. It is recommended that
you store at least one frequency in each band that the system (antenna and radio) is capable of covering.
Make sure radio is turned on and operational, You will be manually keying radio at a low power level at various
frequencies for this step. When using legacy radios, be sure radio is in AM or CW mode, set between 10-30
watts output. TuneMatic will send a PWR message if power is out of range. Note that the following steps only
work AFTER the antenna has been initialized.
1) Start at the highest band of operation (lowest/shortest antenna position).
2) Manually move antenna UP while testing VSWR of desired frequency until VSWR is minimized.
3) Press (STORE) button. Radio will automatically key for one second, and measure power ‘window’,
frequency, and VSWR.
4) If power is too low or high, TuneMatic will spell out ‘PWR’ in Morse tone, indicating power is out of
range. The range is 5-35 watts, with 10-20w as the optimal setting. If you get this error, readjust power
to within the specified parameters. If you are using a legacy radio, make sure radio is in CW or AM
mode, and power is set within 10-20w. Radios connected to the factory interface will automatically set
the power level for tuning.
5) If you are attempting to operate the radio outside the frequency limitations of the TuneMatic (between 1
and 60 MHz), it will spell out ‘FR’ in Morse tone, indicating the radio is out of the operational frequency
range. This error message will also spell out if it is unable to read frequency due to low/no power.
6) The TuneMatic will measure the VSWR. If it is too high, it will spell out ‘SWR’ in Morse tone. You will
need to readjust the antenna position (up or down) until VSWR is no greater than 1.5:1 VSWR. It is
best to adjust the position of the antenna so that a ‘dip’ of the VSWR reading before pressing STORE
for accurate results.
