Re: [Elecraft] K3/P3/expert 1.3KA
My 2k-fa always matches with at least 25 W. 1.3k sometimes goes up and down and needs a second tune but does it at 4 W, which is great for KX3.

Re: [Elecraft] K3/P3/expert 1.3KA
Bob, I think you are right. Your tuner is defective. There are two more owners of 1.3k-FA live next to me . None of us has no issues. Tuners work well up to 3 :1 SWR and beyond that if you tune them manually. I have inverted L for 80m band and with tuner I can cover from 3.5 to 3.8 even though SWR is up to 5:1 some frequencies. 73, Igor UA9CDC 21.01.2017 22:00, Chortek Bob пишет: I've got the 1.3K with the internal tuner and am very dissatisfied with the capability of the tuner.

Re: [Elecraft] K3/P3/expert 1.3KA
With 1.3k I use an internal tuner. It allows for instant QSY and instant antenna changes. I have Expert 2k as well. 4 antennas with SWR< 3:1 are attached directly, and a dipole fed by ladderline is attached via MFJ-998. With MFJ-998 pretuned, QSY takes a second.

[Elecraft] K3/P3/expert 1.3KA
I have a question? I have a K-3/P-3 with a Expert 1.3 k amp. Due to the low swr cut off point of the Expert amp (1.7) and the high swr of my antenna (2.3) I am looking for a Antenna Tuner. I have selected a Palstar HF Auto. My question is what will the Expert amp do when the tuner is tuning. I was under the impression that since the connection between the K3/P3 and the amp and the tuner are all 50 ohms, and there fore a 1:1 swr the amp would see a match of 1:1 and there would be no reduction in power due to the antenna mismatch. Is this correct.
