Hope you do fix it yourself Bernie, It can be a real learning experience and if not, I'll be glad to try and help.  The only really tricky part is replacing the 5351.  Everything else is pretty straightforward.

If you have an oscilloscope,and frequency counter, carefully probe the clock outputs on the bottom pins of the Raduino. Clock 0 is the BFO and should show a sine wave with a frequency of 11995-12000 KHz  Clock 1 will show the receive local oscillator and clock 2 will show the transmit oscillator.  If in CW mode it should show the exact frequency the display is tuned to.
