Owners Manual and Detailed Operating
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio electronics technician for help.
This manual is divided into chapters which are arranged in logical, operational order. The items in Bold
are important notes, Italicized bold are even more important, and Italicized bold underlined notes
are critical informational statements. Section "G" contains a quick start guide for users already familiar
with the product.

Not used. 3) Coax connections- The two SO-239(UHF) connections are identified as follows: RIG - Connect this to the radio through the supplied 3’...
  • Page 4 Connect 3’ RF coax jumper from HF radio to RF connection labeled RADIO of TuneMatic, c) If applicable, connect HF amp to RF connection labeled ANT of TuneMatic and HF amp RF OUTPUT to antenna. If you do not have an HF amplifier, connect antenna lead to this connection of TuneMatic.

    The sum symbol on the remote will flash on and off during antenna movement. 5) Once current limit is reached, antenna will stop moving, and the TuneMatic will spell out ‘C L’ in Morse tone. 6) Antenna will move all the way to the bottom (lowest/shortest) position of travel until it reaches the lower motor current limit position.

  • Page 6: Re-Initialization

    Power to TuneMatic is interrupted during antenna movement – If the TuneMatic power is disconnected while the antenna is moving, it will cause the pulse count to lose track of where it was last. TuneMatic detects this loss of power, and automatically puts TuneMatic into the uninitialized state. This process assures you that the antenna pulse count integrity is maintained through all operations.

    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.

    (with the ‘M M’ Morse message), and will also send the Morse message “T C” indicating a completed tune. In the event TuneMatic is unable to find a tune at or below 1.5:1, it will find the best VSWR match possible.
  • Page 9 TUNE to recall it. TuneMatic will simply move to that selected memory position. If you turn off the rig while antenna is in motion, it will force TuneMatic into an de- initialized state, and you will have to re-initialize the antenna.

  • Page 10: D- Factory Reset

    Missing pulse detection- Once initialized, this detector keeps track of pulses during movement. If the antenna is moving, and the pulses stop, TuneMatic will stop the motor, and spell out ‘P E’ in Morse tone, indicating pulse detection has failed. It will also force TuneMatic to un-initialize.

    DIP switch settings inside the TuneMatic chassis. It is also heard when the upper and lower limits have been reached during initialization.
  • Page 12 ReTune: TuneMatic is re-calibrating and re-tuning the stored memory by re-tuning. EEEEE Stored Tune error Heard if TuneMatic is unbable to tune an previously stored memory after the re- tune attempt. It may be necessary to check antenna system if this message is heard, or attempt to tune again.

  • Page 13: G- Quick Start Guide

    At this point, you can recall the stored frequencies by setting radio to stored frequency, press TUNE button, and TuneMatic will recall stored frequency, and move antenna to set point. The more that is stored, the more presets will be filled up (or overwrite).
  • Page 14 Exchange: Should JT COMMUNICATIONS LLC elect to exchange a Product due to a covered defect during the warranty period, the replacement unit may at JT COMMUNICATIONS LLC’s Sole option and discretion, be new or one which has been recertified, reconditioned, refurbished or otherwise remanufactured from new or used parts and is functionally equivalent to the original Product.
