K40 RTTY
Just finished the RTTY board for my K1EL K40 keyer. This little thing is amazing. I still have an old Model 19 RTTY machine out in the garage, that I used to use with a HB ST-6 Demodulator. This little box, smaller than a paperback book, does all that that machine and the ST-6 did, even has an LCD readout. It works better on weak signals than the old setup did, with its painstakingly tuned filters made with 88mh toroids. With this, and a little rollup mini keyboard, along with a little QRP rig like my RDX-109, and I am portable RTTY, with battery power. (It will work with a CW QRP rig, if you modify it for FSK, which I haven't gotten to yet).
Some things new are kinda neat....
