W6JL amp v1.1

My amp had an initial outing in a not totally finished configuration, several things were missing. 

In short:

  • Added a bicolor ON/TX led
  • Made the filters pluggable

  
 

20M LPF. Capacitors are 630v SMD.

 
  
The 20M filter shows enough attenuation by 20MHz to also be usable on 30M as expected and tests confirm this.

Done just in time for some small summit to summit party…

Only thing remaining is the SWR/display board.
