Can one of the testers please comment....
My main interest in the K3 is for transverter driving from 10m
Can someone provide info on what birdies if any they find around the 10m
band receiver
My K2 was less than acceptable in this hence the reason it got sold
Is the K3 10m section free ?? Anyone comment?
When I first received my K3, I tuned thru the bands specifically
looking for birdies which I felt might cause reception problems...
e.g. birdies which I COULD find with NO ANTENNA connected and which
were still present when an antenna for that band was connected, and
still strong enough to be a potential problem.
For 10M, I found two spurs:
29.085.55 MHz Moderate
29.661.70 MHz Strong
I reported them to Wayne and the other Field testers. Wayne
immediately responded,
suggesting that I double-check the physical (mechanical) grounding of
the shield
immediately behind the front panel "sandwich" of PC boards to its
attachment point
on the top-left side of the radio frame.
Sure enough, the screw at that point had not been securely tightened
by the assemblers.
I snugged down the screw at that point and re-checked for birdies on
10M... GONE! The only birdies I could then hear (no antenna
connected) were completely covered when my 10M yagi was attached
(note: the band was DEAD, and there was no QRM nor QRN present).
NOW... the ONLY birdie which I've found, and which I would classify
as even a possible problem appears around 1.855MHz, and it's not all that bad.
I think you'll be happy.
