Today - after abt 1 year abstinent - I grabbed the uBITX V 6 - assembled 2020 January
For my CW (QRP) operating - It has modified with
- Nextion Desplay
- AGC from Kit Projects
- Audio Filter from Sotabeams (Laserbeam VARI)
- Audio Amp replaced and optimized (also LM-386)
The QRG is abt 50 Hz accurancy
Suddently the vertical (8.5m only) was tuned by CG-300 and I started to call. Makes 6-10 Watts
20 / 60 / 30 m todays CW QSO from HB9 to DL / G4 / F8 / IZ3 / OK2 / S57
Its really a fine Radio - I am really satisfied,
Have now the idea to enhance the Audio part with a small amplifier. (for my QRP ears it's still too noisy) The choosen Module is the PAM8403 - STL-1109) first expirience done - seems much less noisy.
After success will this also do with my uBITX V5
