[Elecraft] K3: Any SSB user comments regarding the new synth?

[Dave Olean]

I bought a nifty up converter that converts everything from DC to 500 kHz up 
to 10 MHz and can listen to the low freqs on my K3 there. It is made by 
Jackson Harbor Press and has some mods made by Clifton Labs. There is a lot 
of info on the Clifton Labs website about using this kit.  It was really 
cheap in comparison to even a single Synthesizer board and there is no 
sensitivity roll off. I think I paid $14 and had to add a diecast box 
enclosure and a DC feedthru connector with two BNC jacks.  NAA is very 
strong as are a myriad of navigation beacons and a few low band broadcast 
stations from Europe and Africa. The big problem is man made noise from all 
sorts of consumer products. I use my 160 M beverages to receive.  You could 
also make up or buy an active antenna and maybe get more isolation from man 
made noise.  It would have to be matched as the normal input is low 
impedance. I think the low freq converter is a great amount of fun to play 
with. $14 is about what you pay for a good hamburger these days!!
