I concur with Jim's comments on loss. I view one should always look at
the component which contributes the greatest loss in the system, that
is most often the feedline. One should strive to improve the condition
by using a line type of less loss. {i.e. better quality feed line} and

Thanks for this excellent post, Alan! IMO, "mismatch loss" is a figment
of the imagination of those who never get outside the lab. Transmission
lines was one of my favorite EE courses, and I never heard of it until I
heard it referenced in online discussions a few years ago. And the

Hi Al,
Yes, but don't forget that the connector "loss" is a mismatch loss, not
absorptive power loss. In other words, it affects the SWR slightly but
does not actually absorb any power.
If you are using any kind of antenna tuner and tuning for 1:1 SWR,
mismatch "losses" have no effect. Eve

Chris,
When I built my K3 years ago, the Sub-Rx didn't work. I found I had
plugged the synthesizer module (KSYN3 at that time) into its socket just
one pin off - very hard to see. Corrected it and never looked back.
Fortunately, no damage to the synthesizer in doing this.
So maybe?

Chris,
First make sure you have your filter configuration set correctly (including
offsets, etc). I highly recommend you use the K3 Utility to Configure the
Crystal filters. You didn't mention how you set up your K3 as far as antenna
input to the sub receiver. I use the BNC connector on the
Mike,
I don't think I have seen this as a suggestion so far in the thread.
It is important that you dress the cables for the SVGA option exactly as
shown in the installation manual.
If they do not want to stay in place, use a ty-wrap around the cables.

The losses pile up for those running QRP or QRPP. I have
frequently thought that a QRP system which has the final
amplifier at the feed point of the antenna would be very attractive.
A crude way of accomplishing a feed point amp would be to take a
radio like the Rockmite and place it at the fe

Excellent. Thank you, Alan. Data for this particular measurement are very

I have experienced this too. Cleaning the contact with a small strip of paper
helps for a while. I'm wondering if the contact closure current may be too low
to overcome the slight surface corrosion that develops over time.

In addition to tuning your rig, I can also rescue a building project you might
