2. WSPR has long 1 minute 52 second key down transmit times. I plan to transmit on alternate cycles, i.e 2 minutes transmit and 2 minutes recieve. Will the uBitX support sustained output of 5 watts sith this duty cycle?Depends on what band and how big the fan is. Seriously it does require moving air to cool it.
I wonder how many are in tight boxes and cooking the finals.
I never noticed frequency stability issues. TCXO is better but I have no proof its needed or required.
