I really ought not step into this discussion. Obviously the Elecraft
Reflector is a mainstay of CW ops.
I've been using digital modes one eme since 2003. Back then the
introductory program was JT44 which was supplanted by JT65 within a
couple years. Then many variants were done to address conditions on
certain bands or certain prop modes. WSJT was formed as the folder
holding most of the new formats plus JT65. MAP65 came out with
ability to display 100-KHz of a band showing all signals and even
decoding all of them to display activity over the sub-band. Kind of
like a P3 on steroids.
The two digit negative signal strength numbers show SNR based on a
bw of 2.5 KHz. -18 is about the lowest level signal one is able to
hear. If one were using a 500-Hz CW filter the same signal SNR would
be -11, or with 100-Hz super narrow bandpass the SNR = -4 dB which a
good CW op should be able to copy (perhaps with a little difficulty).
It all started on 2m-eme, and for years mainly was about eme. The
"old guard" on eme grumbled and said it would never last. Today
there are maybe a couple dozen CW-only eme ops on 2m in the world;
99% have gone digital.
FT8 (as I understand was created by Joe Taylor - K1JT for HF users in
mind). It started when a few tried JT65 on HF, then discovered
WSPR. Now FT8 is gaining in popularity on HF.
Whole world is moving on. K3 and KX3 are SDR's. Everyone on this
list used a computer to read it.
