[Elecraft] K3 60m ERR TXG

[Dave G4AON]

At a carrier frequency of 5.260 MHz my K3 is giving spurious signals 
approx +/- 660 KHz from the carrier at -54 dBc, output level 100W 
derived from the "TUNE" button operation. The spurious levels increase 
as the K3 is set to lower frequencies and is quite clean at the top of 
the 60m band.

I think you will find the approval is invalidated if the importer/dealer 
modifies previously approved equipment, unless the certification is 
re-applied for. Including, or not including, 5 MHz is irrelevant if the 
equipment is approved with that band in the first place.

The relay click is related to the KBPF3, if the KBPF3 is turned off in 
the menu there is no click.

If the relay has clicked, you are no longer on the 60m band. If you
have the broadcast filters, you may well be in general coverage mode.
Unless you have the rig configured to disable out of band operation (I
think that is the factory default), there seems to be no problem.

The lowest UK authorised channel centre is 5260kHz , making the lowest
channel edge 5258.5kHz

Incidentally, looking at the RSGB 5MHz FAQ
<http://www.rsgb-spectrumforum.org.uk/5mhz%20faqs.htm>, it would seem
that amateur equipment capable of 5MHz operation without modification
can't be CE approved.
