I still use the Burhans converter along with my K3 to copy VLF. I'm feeding the converter into the receive input on my K3. Lately I have been using the MULTIPSK software by F6CTE to decode MSK in the 300KHz range. It's abit out of the realm of Ham Radio but it's something I've done for years.
You can download the software at, http://f6cte.free.fr/index_anglais.htm ----- Jack WA9FVP -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-H-Mode-Mixer-tp6889343p6899060.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
