I opted for a 2.1 ssb filter hoping to be able to enjoy phone contesting just a
little bit more but so far I haven't found the magic elixir for phone.I only
replied to the post after seeing "information garbling" from Don. That is
exactly what happens to me with whatever filter or
Windows has a mind of its own. It assigns ports as and when needed. Once done
it will keep it until something else changes. Just remember to check if it
doesn't connect in the future.

Finally got it setup properly, with thanks to all who replied. I took

Good Evening,
The bands were not kind. 20 meters was weak with deep QSB. 40
meters had less QSB but was weak and going long. However, there were a
few folks out there at ESP levels who made it into the log.

"What are recommended dummy loads to consider for use when running the K3 TX
Calibration?"
Thanks to all who've replied both on and especially off list.
The general consensus is that BIRD makes the best dummy loads. Avoiding units
that incorporate BeO is a consideration.

Yes. I use 2.8 kHz filters in all three of my main receivers, and 2.7
kHz in my Sub Receivers. The better flatness of the 2.8 kHz filter

I would suggest trying again to recalibrate it. The recalibration can
be a long process of trial and error with the results measured over
several days.
That is a lot less expensive than buying a new one or sending it to

For SSB, I tricked my K3s out with a pair of matched 2.8s (needed for diversity
reception) and a 2.1 that frankly doesn't make much of a difference. I also have
the 13 kHz filter in for wideband RX and 10m FM (and if I ever wanted ESSB

I have a db Products 50 watt dummy load which was sold on ebay as
surplus cellular test equipment. That should mean it's good to a GHz I
guess. Even though it's only 50 watts I have used it briefly at 100.
There used to be lots of these on ebay but now all I see are 25 or 30
watt versions.
Some of the best dummy loads are built from Caddox Thick Film Resistors.
The 50 ohm resistors are non-reactive and flat up through 500 MHz.
They MUST be mounted on a heatsink to achieve their power rating.
Using careful wiring practices (close to zero length leads), you can

Lee,
The 2.8kHz filter has a flatter passband and steeper skirts than the 2.7kHz.
But remember that this is a roofing filter, the DSP provides the actual
filtering for the K3/K3S.
The purpose of the roofing filter is to keep strong adjacent signals
from overloading the Hardware AGC and the
The 2.8 has better symmetry and no frequency offset. Personally, I have no use
for a 2.1. If you are a CW or RTTY man get a 400 Hz.

I have the 2.7 and 2.1
Try to find carbon resistors as newer film resistors may be reactive.
Older carbon resistors have a tendency to migrate upwards in value. Be
sure to check them with a meter.

Although I have the standard 2.7 kHz filter in my K3S, the 2.8 is
reported to give a little bit better SSB sounding audio. From
experience with another radio, opening up the SSB BW 100 Hz gives a wee

That is a really good question Lee and the answer can be very complicated. It

I find the 2.1 KHz filter useful for SSB contesting when the
band is crowded. At other times it also seems to reduce band
noise when it is engaged. (The other filter that will be engaged
in my radio is a 5 pole 2.7 KHz filter.)
If you set a low cutoff of 350 Hz then the 2.1 KHz filter will
