As for the stability, I was referring to the video's assesment.
The 100mw output. Well, I have a key and have practiced, but for whatever reason I could never focus enough to actually use it like a keyboard. Sadly, I do not practice enough to be active on CW.
As for other digital modes. I actually used to use them all the time as I'm more introverted and most ragchewers are extroverted so it worked for me.
These days, I actually prefer SSB over digital modes, just not ragchewing. Most of my contacts happen during contests even though I don't actually participate as a contestant.
I'm more a fan of the physics of electromagnetics than I am someone who just wants to chat over HF/UHF/VHF.
