I am trying out the CW mode also, BUT I cannot build/wire anything, because of my very rare physical handicap.
Can only use a keyboard as input
Therefore, must use either of 2-keyers that can accept a keyboard as input (besides hand, automatic or semiautomatic keys).
I'm now trying the MasterKeyer MK-1 (hard at programming) and the MFJ-495, either for my direct keying. I use either FLDIGI or CWget for receiving. Still in the on-going process.
