When Farhan released the new V4 boards, one of the advertised changes from V3 was a better distribution of output power across the bands,
realized by changing C81 near Q90 to 470pF.
I tried to replicate this change on my V3 board but the net result is about 1W out across all the bands with a supply voltage of just over 12V.
I noticed that in the V4 schematic R83 changed from 10 ohms to 2.2 Ohms so I made that change as well and it made little to no difference.
I also tried adjusting RV1 and it does make a slight difference but there is very little room for adjustment on this pot so the change is insignifcant.
What am I missing ?
I reverted back to the original components and I am back to about 5w out on 40m and 1W out on 10m with 12+V supply.
