You can configure the amp via the MENU to power up in the stand-by mode. Also

You should have the amp connected to the K3 via the multi conductor cable and

Just purchased a NIB P3 for my K3S station. Love it!
Question - is it normal for it to initially power on with a bright white
screen while it loads? This is very brief, but sure makes a flash. If
normal, then so be it. It is powered from the DC jack on the K3S. I
always switch the

I just took mine to the authorized Fed-X shipping store and let them deal with
it. No hassles. Less expensive than UPS and faster service.

Based on published numbers, the P3 is 6.1" wide, the K3S is 10.7"

The RX Ant In and RX Ant Out are protected during transmit. As to
protecting the input of the SDR-IQ, make sure you use very good quality
connectors and very good quality coax such that any transmitted RF is
not picked up by leakage into these components. I use Amphenol BNC
connectors and
Thanks Wes. I hesitated to un-stack the KPA500 off of the KAT500 and
disconnect all the cables. I suppose I need to look at my
configuration to reduce the likelihood of any damage to the PIN diodes
in the KPA500. Lightning protection is good on the outside of the

I first suggest updating to the most current version of WSJT-X.
On receiving FT8 signals, what is the DT time shown for most received signals?

I didn't find the answer in the manual, so I'll ask here. I do see in
the manual where bleed resistors are applied to the unused antenna

Selector. etc}
My question, do the relays in the tuner take the center conductor of all
Yes, regardless of how good they look, always snug the PL-259 with a small pair
of Channel Lock pliers. Finger tight is not good enough. Many of our
connectors today are of inferior quality.
Also due to the use of jumpers, the flexing and pulling is prone to damage the
connection between
Make sure the contacts on the paddle are clean. Drag a business card between

Also reduce the keyer speed a bit.
I use both a single lever and a dual lever paddle. Timing and rhythm is the key
