TM1 Automatic

TuneMatic is a self-contained antenna controller which automatically adjusts the resonant frequency of a screwdriver/motorized antenna. TuneMatic operates anywhere between 1-60 MHz, and supports a wide variety of screwdriver-type tunable antennas. TuneMatic utilizes frequency measurement, SWR detection, and antenna position to perform the proper tuning, and stores the tuning data in a series of internal reserved memory banks, based on frequency and bandwidth. The TuneMatic is independent of rig make and model and will typically support any HF rig with a PTT control line. TuneMatic is supplied with a backit wired remote button panel, which contains all the functions necessary to operate TuneMatic from the driver’s seat.


– Works with any HF radio that contains a PTT line and switched DC power.

– Antenna motor power not drawn from transceiver (does not load rig external DC output).

– Minimized key times when operating- reduces transmit carrier time and band interference issues.

– Simplified ‘plug-n-play’ operation.

– Unique learning technology; the more you program it, the smarter it becomes.

– Operates multiple antennas:(TarHeel, HI-Q, Scorpion, Diamond).

– Internal frequency, pulse count, and SWR sensing technology.- Supports both manual and fully automatic operation.

– Continuous 1-60 MHz range.- 3000 memories, frequency/bandwidth dependent.

– Utilized non-volatile EEPROM memory, with over 1 million r/w cycles, with over 15 year retention.

– OPTIONAL automatic RF amplifier bypass during auto-tuning; eliminates need to turn off amp during tuning.

– Self-calibrating  PARK feature.

– Multi-speed motor operation; triple-speed motor control for fine-tuning.

– Programmable motor current limit sensing.- Remote button interface- optically isolated RFI protected.

– Morse code alert and status messages.

– Automatic rollback on pulse or power failure; operates during antenna pulse sensor failure.

– Triple safety using motor over-current, soft limit, and missing pulse detection.

– Surge/polarity protected 12V DC power input.- Powers on/off from rig power button.

– Will interface over 50 makes/model radios, such as: Icom, Kenwood, Yaesu, Flex, Elecraft. Xeigu

– Firmware field upgradable; seamless, no re-programming necessary when upgrading.

– One-year parts and workmanship warranty.
