I worked with this little device in SSB GB MM DL ON HB9 I EA UA OZ PA VP W K 2M OE... with only 2 Watts ( the amplifier is capable up to 15 watts )
The VFO is ultra stable . Audio sound great , modulation is just fine.
I realized this QRP with the help and/or ideas from Ashhar Farhan , Hendrikx, PA0EJH , W7ZOI , IK3OIL,PI4RAZ and other HAMs .
Yep , an other BITX-20 design
