[Chuck aa0hw]

only 2 LSP Plugins are needed for DIRECT CONVERSION from VLF CW to AUDIO CW

for VLF RECEIVE, a sound card's line input is being used with a FERRITE ROD LOOPSTICK ANTENNA attached to the LINE INPUT runs straight over to the input of LSP PLUGIN SIDECHAIN GATE MONO LV2 plugin

one of the advantages of LSP PLUGINs for DIRECT CONVERSION/ is that the LSP PLUGIN SIDECHAIN GATE has a CW FILTER that can be adjusted to output a very nice shaped CW NOTE according to your preference for HARD/SOFT keying on the CW ELEMENT edges... (no need for a 3rd plugin that does bandpass filtering etc..)
