[Elecraft] Re KX3 booster

[dyarnes]

John and All,

I’m not necessarily recommending these amps, but you may possibly be confusing them with a prior model line--  The original  “HLA” series, such as the HLA 150 and HLA 300.  Those amps were marginal at best, although if you ran them well below their rated output they weren’t “too dirty”!  Hi.  RM Italy also sold a line of amps that didn’t even have proper bandpass filtering as they were intended primarily for CB.  I think those just had an “HL” designation.

These newer models supposedly are a much better design.  I first saw them at Dayton a couple of years ago.  The price went up substantially too!  Supposedly these are all FCC certified, whereas the prior models were not.

I'm surprised a reputable company like DXE would sell the brand:
