Just started a new build of a UQRSS rig..
This one will be for experiment with trying different frequencies etc.
Anyhoo, I've added a photo on here (G4JVF) of the PCB part way through showing that I'm using inline headers male/female to make changing components easier.
In particular, capacitors C3/C4/C5 can be easily swapped by plugging in which saves damage to the PCB (C5 is shown plugged in on the photo).
The crystal also has it's own socket.
At the PA end, the filter will be external to the board so I can plug in a filter to suit the frequency in use.
The two posts near the C10 position (bottom right) will carry the signal via coax to the filter sockets.
The PA will be a pair of BS170 and their heatsink plate will sit in the space where the on board filter components would have been.
All the other male posts will make soldering in/out leads easier than soldering direct to the PCB.
That's the theory, more as it evolves
