[Elecraft] NOT the feedline

[Peter Dougherty]

I have an HF-Auto that is just unsuitable for contest/DX duty, even with the kludge workaround software--which often doesn't work right. I gave up on it and hope to sell it to a ragchewer who will undoubtedly make better use of it than I ever could. 

And I agree about the Palstar support being...unpleasant. I saved up for 3 years to buy that and I feel sick about it. I would like to find a good high-quality tuner that is reliable and able to comfortably handle 1500W and (preferably) tune automatically via CAT control.

My recent experience with Palstar has not been good. An expensive DL1500 dummy load in which the SO239 had not been mounted correct bwith the locknut still ten turns loose,

requiring dismantle and repair new out of the box by myself. Also a new expensive AT2K tuner in which the roller inductor shaft had not been graphite greased nor tensioned.

My SPE amp @ 400w went out on alarm quickly until I disassembled and repaired myself. I found Palstar support rude and in self denial of the issues I raised.

In hindsight I should have saved a heap of money and gone with MFJ.
