[BVARC] Any uSDR users in BVARC?

[Stephen Flowers]

Dan,
Good afternoon.  I uploaded firmware on my tru(SDX) ˜2 years ago and made this video.  In the AVRDUDESS v 2.14 program I called up the Arduino under “Programmer" and ATMEGA328P for "MCU".  That specific part of the procedure is located at the 5:20 minute mark of the video.

Note that I didn’t use a physical Arduino board, just called it up virtually in the SW.

Hopefully that helps you.

73,
Stephen (W2WF)
