30m Oscillator (night 4)

I made a few changes tonight and feel pretty positive about the limited time that I had to work on it.






Today's notes:

• 
  I removed the tank circuit and replaced it with a resistor on the collector of Q1.
  (The oscillator should now be a wide band design for future projects.)
  
  


• 
  I re-biased Q2. (This morning before work I built a spreadsheet that helped me better
  understand the values of the components and the impact on the transistor.)


• 
  The loudest harmonics are now about 42dBm down. (The two loudest are the 6th &
  7th harmonics.)


• 
  The power at the output of the filter is about -10 dBm or .1mW


• 
  I updated the schematic with the changes.
  
  

Next steps:

• 
  Move this to a copper board with islands or Manhattan pads


• 
  Design an additional gain stage (or two)
  
  


• 
  Research "class AB" and "class C" amp options
