I like and respect your tenacity. You have a 'hang in there attitude' that I really, really respect.
Bust yer balls to get that recording setup bro !
I like the tambre of your voice, it has a nice quality.
Practice singing gentle, medium volume LONG tones, with a tuner. Just try to keep the needle in the ballpark on the tuner.
Sing five note scales, like little modal scales, blues scales.
Be cool tenacious one.
