AutoFT81.19

JTDX-VU0.7.5-RC4
JTDX-VU is JTDX 2.2.159 built for the VUCG community and kept up to date: native apps for macOS (Apple Silicon and Intel), Windows x64 and Raspberry Pi / Linux (arm64 .deb), with the features VU DXers asked for added on top. It installs next to a stock JTDX as its own app, with its own settings and data, and on first launch copies an existing JTDX setup across, so callsign, audio, rig and logs carry over.
