Beta release

Should work as original firmware
Blink test alternates leds when blinking

Alpha quality

Missing blinking led and push button action (the tracking generator is always on).

Works in VFO mode and sweep mode.

The D6_blinkTest.bin just makes the leds blink to show that you have successfully reflashed the device.

Original firmware from vendor

It is included here in case you want to return to the initial state of the device.

This release was in the original .rar package from the vendor under directory 4/The second batch ...203

The source code of the initial software is main.c as included below, disregard the source code .zip that github has created automatically as I created this release.
