To accommodate the needs of soaring pilots, TruTrak is testing a dual
turn-rate feature for their new solid-state T&B. An unused pin on the power
connector will be used to select either a 1 or 2 minute turn rate. The
instrument can be installed either way, or a switch may be used for
in-flight selection. A DPDT switch may be used to power it on at either
rate (1-min / off / 2-min). I will have one of these units in a few weeks.

My first flight with this instrument revealed inadequate power filtering.
At low squelch settings, my transceiver picked up the display stepper motor
doing its thing. TruTrak has already addressed this problem.
