Pulse width modulation as a throat irritant?

[WolfeReign]

wow, been a really long time since i have been around these parts, and my first post gets to be a question that has me scratching my head

Long story short, i finally got my greedily little paws on the itaste svd which of course has the 33Mhz {or as PBusardo has called it: thrity-three-three chip} but since Thursday {and today is Sunday}, i have been getting rather odd and bad throat irritation...

Of course i am going through the usual cast of suspects {juice strength, flavor, voltage/wattage, juice device} to make sure it is not one of those as i swap between my mvp {version 1.5), the svd. I would use the vtr but the inner threading has stripped or something so no go there {DERP!!}. But while i cycle through the different "tests" i have to wonder if other people find they get a irritation from using the pulse width modulation devices such as the svd?

It's been my personal experience that the regulated mods utilizing the 33.3 hz chip produce a hotter vapor than those using a higher frequency (Provari, MVP). Try turning your voltage down about 1 volt or more than your usual settings to try to find an acceptable vape.

I'm not sure, why would you get irritation for such thing?
To me it sounds more like PG intolerance or to high nic, because svd will give you better hits and you might need less nic. than with say an ego style.

edit:

If this is the case, maybe it was a good choise of me to go Mech instead of the svd as i wanted to buy.
If baditudes post is right. I still find it odd that it can irritate the throat (yes i read the thread)

Some really seem to like the 33.3 Hz devices while others definitely do not...It is a matter of which type you are. I can say that those who dislike the chipset complain of some of your same issues. Sorry you're having troubles-Dave

 

[CalamityJess]

I have an SVD coming. I'll be anxious to see how this turns out for you.

 

[Way2Gone]

Pardon me for jumping in on this post, i do apologize. I was thinking about getting the svd myself but as i have read above about the 33.3 chips in most of innokins products, does the MVP 2.0 not have the 33.3 chip? Is it overall the better route to take when buying a mod from innokin? Does it Provide a smoother type of vape?

Again, Thank You and sorry for the interuption.

I've never noticed anything like that in the 6 months I've had my SVD. It is a noise at best, and nothing more.

Currently vaping a Rocket kayfun-style atomizer at 15 watts on my SVD. Smooth, yummy clouds with a 50/50 blend, 12mg nic.

 

[crxess]

More likely improper settings than frequency. may even be an air flow issue.
Vamo - Mose 2 RMS - 33.3 Chip is very stable no HOT peaks
5 Kick Clones - all 33.3 chips - No issues even at 12 watts.

Lots of reasons for a sore throat, but frequency is probably way down the list.

I had run a test with both the vamo3 and SVD on an O-Scope and found that neither of them created any substantial waveforms that could be considered a "pulse" both units were set to 4.0 V and measured at the 510 threads ( without a load resistor) and the voltage differential was .02 V. With a load resistor of 2.7 ohms ( 10W resistor) the trace was flat at 3.8V. ( load resistor caused a .2V drop between resistor and 510 +post)

I dont see how a .02 voltage differential would make that kind of difference....

Pbusardo has your post looking way wrong set-up its duty cycle is hitting about 6v that is considerably a lot higher than what you are reporting, but your unloaded he is loaded @3ohms.

No, the MVP2 and the vv V3 from Innokin do not use the 33.3HZ chipset

 

[Baditude]

Agreed. Flat line on the oscelloscope just like the Provari, which fires over 800 Hz.

:O went to put around in second life and talk to some in one of groups {ton of e-cig users in novatech} and i just cam to peek if i had replies, and wow......lol here goes, a marathon post {PS: i changed my post to 33 from 333 opppps}

I have a low res {1.7ohm} set to 3.4V {i flunked math so the wattage is confusing but i am adjusting to taste}....so far nothing bad....me thinks it might be related to the juice {i get it from the mall here --- And i loves my root beer too..........

I'm not sure, why would you get irritation for such thing?

After making this post i swapped to the same {i hope} mix of 70/30 but instead of my beloved root beer i am using sweet punch....i might need to let the root beer steep, or swap to a atomizer for it. I would use my vtr but i think the instead threading to where the cart gets screwed down is stripped {OPPPS}....either way i love the svd in the 18490 config.....reminds me of a sonic screw driver

no real troubles {yet}, but it is wiser to eliminate all the probable, so that what is left no matter how improbable is the answer

I have an SVD coming. I'll be anxious to see how this turns out for you.

Mind if i ask what config you are going to run it in? i find the 18650 config is a monster while the 18490 gives me something very comfortable. the downside is my 18650 batter gives me about 11hrs run time and the 18490 about eight or just under ten hours. Other then that i think you will really like it

soon.....so very soon i think i will try those kayfuns out......

Still Safer to ask as i rule out matters one at a time here

Agreed. Flat line on the oscelloscope just like the Provari, which fires over 800 Hz.

I have two of the mvp's {1.5} and they are real little work horses, and have prompted me to order two of the version 3's {wife if still rolling her eyes at my itaste 'hoarding'

alright thanks.

If you figure out your throat irritation please share. I'm fighting it too. Seems to be certain flavors (that have the same nic and pg/vg as the rest that don't bother me) that never bothered me before this weekend, no matter what device I'm using or what voltage. I'm really tired of Ricola lozenges right now >.<

That line cracked me up.....i am used to seeing it on second life with a sound effect though....not laughing at the misfortune.

I think it could be a increased pollen/allergen? If you weather has been up/down/sideways/inside out ... then one thing i noticed moving from the east to the mid-west was the increased elevation played havoc on my body and i needed to drop my nic level .... i cannot honestly give you sound advice here ... but i can say if you can even get some sample juice at a step or two lower then what you are using for those flavors that might help or {sweet mother purr i hope not} there was a bad batch of flavoring somewhere?

PS: Halls black package for the win

Something i tried last night that seems to help too, and though it sounds noodles might help: Are you using a glass drip tip? Delrin? stainless steel? different shapes? I was using the metal drip tips that come with the kanger pro tank then switched to my stainless steel dragon head and cobra head ones and seems to be working a little better....sure the taste is not the same {to me} but whatever works right now

I actually added some VG to the tank of the flavor that's bothering me as was suggested in another thread and that has mellowed the harsh a little (sorry, Pauly Shore just came out of my fingers there). I think it may be time to drop the nic to 18. Unfortunately I'm not a DIYer so I don't know how to adjust my current 24mg flavors in the partial bottles I have without destroying them completely so I guess I'll just replace as I go.

There's a tremendous difference between 33Hz and 33MHz. I don't know the actual frequency of the MVP, but it is a LOT higher than 33 Hz and I doubt it's 33 MHz. There are a lot of lower-end mods that are 33 Hz, the MVP is not one of them.
