In summary: the alignment tools built into the radio consist of a signal generator which
injects a signal into the RF front end, and digital signal processing which adds a 250-Hz
digital filter to the existing 200Hz analogue filter, and calculates the amplitude of the signal
detected in that bandwidth. During alignment, the amplitude is displayed on-screen as an
intuitive bar across the bottom row of the display. Using a screwdriver, you adjust the
trimmer component in order to maximize or minimize the displayed amplitude.
Unplug the antenna during alignment of the radio! Connect a 50-ohm dummy load
such as the QRP Labs dummy load kit http://qrp-labs.com/dummy
When using the TCXO module option, change menu item 8.5 Ref frq to 25,000,000. It
is critical to this before any further alignment. Enter the menu system as described
below, and turn to menu 8.5, edit it to 25,000,000.
