mcHF Kit
Kit consists of two boards with populated SMD parts and extra components supplied in plastic bags.
It is worth pointing out that the kit requires some advanced soldering skills and knowledge in electronics as mods might be required. Also extensive tuning and calibration might be needed, or sometimes debugging of problems. It is not recommended as first kit or if you expect to be on the air after few M3 bolts tightening.
Thanks to Chris m0nka for this great transceiver!
Have fun! ;)
