What's in this update
MCU 2.05 / DSP 1.29
- 2M/4M MENU ENTRY CONTROLS TX TEMP SENSING: In the 2M/4M menu entry, tap '1' to toggle between TX TMP+ and TX TMP-. Default is TX TMP+. If TX TMP- is in effect, 2-m/4-m PA temperature will *not* be measured during transmit. This is only required on some early field-test units that have not yet been modified.
