[Elecraft] Possible problem with K3 at very low power

[Stewart Bryant]

Hi

I have noticed something strange with my K3 and am wondering whether it 
is a bug, a feature or operator error.

I am using the K3 to send WSPR at 0.2W, band hopping but on almost 
continuously on one band or another.

The driving program is WSTJ-X in WSPR2 mode with scheduling enabled.

Whilst it always works OK to start with and I get reports, I notice that 
after it has run for a few 10s of minutes I get no reports. It is as if 
there is no o/p from the K3.

If on the other hand I run at 2W and put a 10dB attenuator on the output 
socket, it all seems to work as expected for as long as I run it.

So is this a known problem with the K3, a broken K3 or have I made a 
mistake somewhere?

Thanks
