[Elecraft] [K2] What happens above 28.8 MHz ?

[Steve Kavanagh]

I was just pondering if I could use my K2 for transverter operation at 29.4 MHz, despite the specified upper frequency limit on 10m being 28.8 MHz.  On my unit, at least, the VCO still works.  I can hear signals but it seems they are probably a bit attenuated.  Does anyone have real data on how much the bandpass and low pass filters roll off above 28.8 MHz ?  Are there any nasty spurious signals to be aware of ?
