My first a bark river arrived yesterday, a bravo edc in natural canvas micarta and i absolutely love it! However I can not seem to get the belly of the knife sharp. I tried using the marker trick but every angle i tried on the strop didn't work. Is there a micro bevel or am I using bad technique?

There is a micro bevel, its about the width of a hair. I usually just raise the angle slightly steeper while stroping with light pressure(enough to keep consistant contact with the surface)But not directly at the angle of the micro bevel. Too steep and puts the edge at risk for rounding over.
Aim for behind the micro bevel, at its shoulder

Hmm just tried on 1500 grit sandpaper but no luck.
 
Sounds like your serious about getting a solution. Pictures would really help us help you seriously.

Also details about your techniques.

Remember to use good lighting and at different angles to show the area being reached by the abrasives and the areas being missed.

Otherwise people will just give out good but non pertinent sharpening advice.
 
I'm using the field sharpening kit from Knives Ship Free that comes in a waterproof box. Not sure how to post a picture though.
 


Here a close up of the micro bevel on my Bravo 1 A2


If you lay the knife on its curvature closest to the edge there is still a slight shadow

Do you see the black line between the knife and the strop? That's the cutting edge not reaching the strop to get sharp.


Solution, simply lift the blade until the shadow disappears.

Use light pressure (almost none) and move from tip to heel on each side slowly and observe eash pass for contact. Do alternating strokes 10-20 times.

Reassess by slicing paper for any rips or snags while cutting slowly.



Here are some other options as well.


Option 1 reset the micro bevel.
Option 2 reprofiling to remove the microbevel to a zero grind convex. (Sharper and easier to strop)
Option 3 send to Bark River to sharpen.
 
Short answer.

Sharpen a normal convex secondary bevel at the desired angle. Then through observations, remove the line that distinguishs the two bevels (the shoulders) by lowering the angle to effectively blend it into the main grind repeat this all the way to the top of the primary grind untill it looks like a uniformed convex all the way to the edge.

Now stropping is easier and more effective.

Observation is key.

Here's a video from the MC about convex grind sharpening
