Hello,
I was going to buy a Signalink USB for my KX3, but after reading about the
noise problems I am not so sure. I wish Elecraft would build a USB interface…
It would undoubtedly be a hot seller and I am sure perform flawlessly… Anyone
in support…?

What kind of noise problem are you referring to? I use a SL USB with my K3 with

Going wireless, adding the transceivers, would increase the cost quite a

I have a K3/P3, actually, have KPA500 and KAT500 too but this question is about

If I switch to 10-meters (and, there is activity on the band), the P3 shows the
signals and the waterfall for about two seconds. After about two seconds,
there is a change. The waterfall signal disappears
If you want your panadapter to sample and display a properly I would think
most folks would ASSUME some signal fidelity was in order.
Most don't care about freq response.i guess they dont expect much when
they use hrd or dm780 or nap3 etc.
My single disappointment in the KX3 is that it has a forest of cables instead
of a single USB port. I understand that the available USB chips create a lot of
RF noise, but dang, we've had USB for fifteen years, and it just chafes me that

That is not normal behavior. Check (by replacement) the BNC cable
between the K3 IF output and the P3. In the past there were a few bad

Hi Gary,
This is normal as the KPA500 is designed to attenuate signals the further you
go below the 160M band in order to protect the T/R switching diodes from BC
band overload.

If you are using a K3 with your KPA500, you can connect the antenna for
lower frequency operation to the RX ANT IN port on the K3. That's works well
for me on the AM broadcast band.

Rick,
The roofing filter option for the KX3 serves an entirely different
function. It reduces the possibility of a strong adjacent channel
signal overloading the KX3 at the product detector stage.

kHz are in the front
I took special care to ensure all case covers metal to metal connections were

the K3 Synth unit modules in a way to prevent least problems. I also use a
