[Elecraft] Adding a low noise preamp into the receive line of the internal 2M trnsverter

[Wayne Burdick]

Hi Howard,

The K144XV itself has a high-gain LNA producing a NF of around 1 dB. It cannot be bypassed without a PCB modification. I’d be cautious about adding another high-gain LNA directly ahead of it. 

Some stations have an LNA right at the antenna to establish a low noise figure as early as possible and overcome cable losses.
