Paul, I doubt that anyone can predict the effect exactly without some very
sophisticated modeling software and exact dimensions. I will give a stab at
it, but because you are talking about a very wide frequency band and some
unknowns about bonding and the conductivity of the roof you will have
The secret to that is to get a big-honking-old-fashioned soldering iron to
solder with. I have one that ATT issued my FIL is about 1938 that works
great. I had to change the cord to a modern one to keep from electrocuting
myself or someone else.

The original poster did not mention doing anything to his antenna or feed line.
He just wondered if putting a new metal roof on his house would screw up his
antenna. The answer, I think is probably not enough to notice, so go for it.
A leaky roof is not a joy at all!

Dick,
It is very strange that the K2 would have a problem like that on only
one band. Does your KPA100 have a shield over the speaker magnet?
About the only thing that I can think of is that the speaker shield is
missing and its magnetic field is interfering with the operation of the

Some KX3 owners hear a pulsing or clicking noise when tuning the VFO on higher
bands, especially when atmospheric noise is low. We discovered that the KXFL3
filter module is responsible for nearly all this noise, and that it can be
reduced or eliminated with a simple modification to the module.

The three pins removed in the KXFL3 modification provide control signals for
accessing a small EEPROM on the module. This memory device was intended to

The instructions suggest that realignment of the filter may be necessary if
some of the capacitors are pressed on the board. Is there any simple way to
tell if such realignment is necessary? Is it very likely that if those parts
are not touched realignment is not needed?

Hi Joe,
I just did, and the tuning noise is gone on all affected bands!
To be sure nothing was changed at the filter I will check the sideband
suppression, however I took great care not to touch the caps.

Mike,
What you would be checking for is opposite sideband suppression and
you'll need a very strong single tone signal source. S9 + 20 or
thereabouts is a good level, and this can be on or around 20m. There's a
procedure to do the calibration in the KXFL3 installation instructions,

Been a lot of discussion on this topic so I decided to make some
real MDS measurements comparing my K3/10 (4340) and KX3 (475). I
hope the columns read clear for everyone (I can create some charts on
my website, if not):

In MMTTY make sure that the correct sound card is selected for both TX and RX.
Only a problem of course, if you have more than one card. (Don't ask me how I
know this:-)
Also make sure that the Mark and Shift that you select in MMTTY match the Mark
and Shift (pitch) in the K3.

Maybe the signals are louder on the KX3, which would fool people into
thinking it was more sensitive? I've always thought my K3 was adequate
on 6 meters. Not gangbusters, but certainly adequate.

We're now offering an external low-noise, high-performance preamp that covers
both 6 and 10 meters: the PR6-10. The PR6-10 provides useful gain and low noise
figure down to about 22 MHz, so it can be used on the 12-meter band as well.
In most respects, the PR6-10 functions the same as the PR6,
