[Elecraft] strong signal on 17 m in K1

[Krister Eriksson]

(Copy of this also sent to elecraft mailing list)

Paul, mine is 0n 18.113.7 loud and clear just like a cleane tone, my
guess: 6th overtone from VFO, 18.113.7 / 6 gives 3.018 MHz and my VFO is
ranged 3.000-3.090. Possible your VFO range is not the same as mine. I
can also hear this on my portable Sangean world receiver. If I multiply
3.018 by 2, 3 and 4 etc also these frequencies is well heard on the
sangean RX.  Well in that case nothing to do i guess, I just dont need
to operate around 18.113 Mc:s...  

Perhaps the VFO area in the K1 should be inside some sort of shielding,
and passing thru a low-pass filter before the premix...  

73 have a good day,  / Chris
