Doug,
11.05550 as Raj stated is the correct frequency for a v5 board.? Before you go adjusting things, can you verify that the stock v5 code is in the Raduino nano?? Have you or anyone else uploaded a new version of the code?
If the answer to the question is that it is still stock, then go ahead and adjust the BFO through the settings process.? There will not be a lot of turning on the original code, as every time you go into BFO Calibration the value gets set back to the stock setting of 11.055500 MHz.
It is very important that we know what software is installed, as clock 1 is different (and constant) depending on the board version.? This makes sense as the target frequency for the filter is now lower, the two values for USB and LSB need to be adjusted so that the signal through the 45 MHz roofing filter is in the sweet spot of the crystal filter.
Again, I hope it helps.
