Pulse 24 RDA whistling

[Kazuko]

Hi everyone,

So I bought a Pulse BF Kit today, and I can't help but notice the rda (Pulse 24) is whistling when the airflow is wide open. I can mute it when I open only one hole, not even fully, but the draw is way too restrictive for me.

Has anyone else have this problem?
Also, is there an easy way to fix this? I guess re-drilling would do the job, but I don't have a drill, and I'm not particularly a handy guy... The only idea I have would be to scratch the holes to maybe remove an invisible "dent" that would cause this, but I'm really not sure it'd work (I'm actually pretty sure it won't)

I should point out, I've already tried to builds on this, and I've had the whistle on both. I may set my coils too high, even though this one is a bit lower than the previous one. Still, if the build could be the cause, let me know, and I'll post a picture of it

Edit : the whistle came back with the one open hole, I just opened both wide, and it doesn't whistle. Seems like juice condensation helps muting it, as it seems moving the top cap solves it for a few draws...

I think I may have heard of it happening. May have something to do with the build iirc. I don’t own one so I didn’t pay attention.

Try a site search. You may run into an old thread on it

Whistling is usually caused by coil placement and build. I don't have that RDA so I can't say for sure.

Here are pics to help you see how I built it

I set those coils yesterday late, so I kinda rushed them. Thinking back, I thing they're way too low and too centered. I'll try and build another set of coils, placing them closer to the airflow and higher, hoping squonking won't cause leaks... (I like to squonk to the point where the juice goes around the coils, not only on the wick tails)
