Sure, that is on To-Do list
Some other members here done that with Lime too, but up conversion
is not the subject here
All must keep in mind that my test goes on LimeSDR RX1_W input, with coil removed.
Like to keep LimeSDR RX1_L input optimized for other project on GSM band.
LNA4HF + SDRplay RSP1 make nice rich AM reception on the same 418 kHz NDB
