Is there any chance of you being able to post a video? I strongly believe with the help on TC we can get you making a very acceptable bowl of usucha!!!
here are the parameters I use for ususcha, two chashaku of matcha, 70ml of water ( I always use a hishaku but I just measured it to see how much water I was using). I use water at 80c. pre warm the bowl, dry the bowl. Add the matcha pour in my ladle of water, whisk very intensely until the foam is of a consistency I like.
Do you use a thermometer for you water temperature or check the bubbles?
80c =176f or small bubbles forming in kettle.
Today and usually I've been using about 200ml of water to between 1/2 and 1 tsp - don't have a scoop - but have varied the amounts of each at other times, and it doesn't seem to make much difference. It's annoying me now...can you tell?! I've also tried a variety of whisking actions but presumably not the right one
200ml of water is WAY to much water you will never get any foam using this much water, reduce you water to something around 60 - 70ml and give that a try. I strongly believe after everything you have posted your main problem is using a volume of water that is to high to create foam.
best of luck, you will have success if you keep at it.
