Giving up FT-8 (yeah right)

My mind is worn down by FT-8.

For those who are unaware, FT-8 is a digital mode used in amateur radio where by a signal is encoded in a very limited amount of bandwidth.   The technique to decode the signal is left to a DSP algorithm that is implemented in software (although, the time may be near where firmware might be available, and then again, there is an opportunity for Machine Learning to be involved, but that's for another discussion).

The dominant software used is a package called WSJT-X.  There are countless YouTube videos and web sites that document how to get started and use FT-8.  I won't waste time doing that here.

What is infuriating about the mode is that it's too easy.  It's literally point and click QSO.  There is some skill involved prior to getting started -- you need a decent antenna system, and a decent (or equivalent) audio chain so that you can decode as much bandwidth cleanly as possible.   Technically, a laptop and a HF radio and antenna system is about all you need.  I throw in some audio-chain equipment to enhance my capabilities in hardware to decode and transmit.

Still, it's just too easy.  Maybe that's why it's popular?   Another reason for its popularity is that a lot of DX are using it, especially when band conditions are poor.   When propagation is suffering or in a poor state, then there is something positive to be written about FT-8 (but the same can be said for CW too).  Yet, you don't see a lot of people rushing to buy iambic paddles and learn CW when band conditions are poor.  Instead you find their ringing signals on the digital mode (FT-x) allocations in the band.

Not a stich of code necessary to work FT-8.  All you need is a mouse pointer and a preference.  Truly.

Having put that out, I have used it.   I used it a lot since 2020 and I regret doing so.   I have no issue with people who use it.  Heck, I'm going to end up using it again, soon! FT8WW is in FT8 and everyone needs Crozet Island!  So, I'm not throwing stones from the deck of my glass house.  I am just pointing out that it is wearing me down.

It's also nice to have QSO over SSB and not be looking at the clock to see when my 15 seconds are up.
