I can't say i have ever had a radio "spur on my signal generator" before.
It actually transmits a clean signal every 10KHz till the signal drop so low it cant be heard on another radio and i am talking a radio 5 miles away or picked up on a spectrum analyzer.
If you are on say 27.4050 you will be transmitting clear on every channel below and above for about 60KHZ in either direction. It is not splatter per say or harmonics the 54MHZ 2nd harmonic is all most non existent it is clean signal every 10KHz.
Even when you un-mod it back to 10 meter rig and that is only moving a jumper it does the same thing.
Also it is not the 100 watt amp doing it, I have tried it with the amp bypassed and the final with only the pre driver going and it still does it all be it lower in strength.
I had another radio here the same kind and it was clean as all get out, I didn't have to time to probe it out for comparison. There has to be a part that failed some where that causes it to generate that 10KHz and or pass that signal and add to it each time.
So some radios doing it and some not of the same model dictates that is a failed or removed part in the radio causing it.
