Changing out those transistors have minimal to no effect for the lower bands.? It was part
of the chase for power at 10M and while I did get far better power the spur was amplified
as well.? For me a show stopper.? Others may deem it acceptable and proceed, its
their choice.??
The spurs are not directly impacted by the amp, nor are they caused by the amp.?
They exist before the arrive at the amp.? ?They are not an issue below 20mhz as?
the filters work for that range.? ?The problem is?trying to operate on 15,12 or 10M?
at any power level SSB.? ? ?I've gone though this many times now.??
With the ARRL Field Day (Saturday and Sunday) was upcoming up so I spent time
preparing the VHF station as I do that.? I have not gotten back to the bench yet.
Any solution I apply will be to suit me and I may write it up but it will be 10M only
as my wish is a 80,40,20,10m radio and its doable.??
CW at any frequency there is no issue.
