Firmware, AlphaMax kit, for Alpha 87A Autotune v1.00AT
- Customer Reviews (0)
AlphaMax Firmware (version 1.00AT) adds Autotune function to the Alpha 87A amplifier.
Includes installation and operation instructions, 2 programmed ICs and jumper.
Every 87A made after 1999 already has this firmware, earlier firmware automatically goes to saved memories when you change bands but can not automatically retune the amp if the user saved memory settings are not correct (the drive power or antenna changes).
AlphaMax firmware gives the 87A the ability to dynamically retune if anything changes. This is NOT an antenna tuner.
