Hi Bill,
I found that jumpering the BPF or even the LPF when testing, gave me
results similar to what you are seeing. I didn't start to see useful
results until I had all the parts for all three filter sections
completed. Do you have the LPF set up completely?
I'm not in a position at the moment to test my K1 with a RF probe,
too many other projects on the workbench right now so I can't compare
the values along the TX path with what you are seeing.
There's one other thing...
I was looking at some digital photos I took of my K1 RF board and it
looks like I removed R31 and R32 (they are in parallel with each
other and sit between the Driver output / PA input and ground - see
pp.79 in the K1 manual) but I don't have anything in my notes about
it. I don't remember removing them, but I know I had a few late
nights where I was trying everything I could think of, to get the 10M
board to work. I thought maybe I had moved them to the bottom of the
RF board, and/or replaced them with another value of resistor, but I
just had a quick look at the bottom of the RF board and found that
R31 and R32 are in fact missing.
I apologize for the mistake / omission in the information I posted.
