Re: FedEx invoice for import to UK
开云体育Hello Chris
?
Glad to hear someone else got stung!!! Only joking.
?
I got caught for ?5.72, so FedEx system is flexible.
?
I do know now that it is hit and miss another G I was in contact in hasn't had a demand and that was 2 to 3 weeks ago he git his. aia have had another delivery, about a week or so ago, as yet no demanding letter from FedEx yet.
?

PS
Enjoy the build hope you have better luck than me!

Re: FedEx invoice for import to UK
? Isn't it the recipient/buy that gets charged VAT in the eurozone?? I didn't think the vendor would be charged anything but shipping costs... Yes that's what would make sense. But not anymore. Now the vendor is supposed to collect VAT on behalf of the EU/UK states. Then file tax returns and send them the money collected (or pay a 3rd party service to do so).? I suppose the idea was, that if you are a UK (for example) vendor, then you would be collecting VAT on what?you sell, and you would file tax returns to the British government, and pay the VAT you collected (offset against other amounts you purchased). So why not make it fair, get foreign sellers to do the same thing? Problem is it doesn't really work very well if there are 28 states involved, all with different rates of sales tax ranging from 16% to 27%. What small business can keep track of all that! ?

There are two parallel FETs which are ON at the same time to share the current, which might not result in perfectly equal sharing, but let's assume that holds for the moment.I think the wonky VSWR presented by an Automatic Transmatch (ATU) will result in excessive VDS and this will result in a dead FET faster than the brief over-current event heating the die. Using a TVS device (bi-directional Zener), mentioned in another thread, has completely resolved this issue for me. While others have been concerned by the additional capacitance affecting the output LPF, I have observed no discernible change in the output spectra of the QDX (low-band) for the 2nd-5th harmonics. All are below FCC limits with and without the modification. I don't understand the resistance to the addition of this trivial protective measure.

Re: FedEx invoice for import to UK
Hi Joe Yes exactly as I thought. I have MORE THAN enough problems already,?without?being tax collector for 27 EU member states plus UK!? Still in general - shipping to EU and UK does seem to work. It works almost the same way it always did in the old days. When the package arrives, it is assessed for tax, and this is collected from the recipient.? The original announcement by EU and UK sounded scary because there was no mention of just being able to ignore their nonsense completely, and carry on the old way. It wasn't publicized anywhere. In my case, I can't even keep up with my emails let alone be a tax collector even if it sounded fun (which it doesn't). So I had no choice but to ignore them completely, then I found out ignoring them completely does work.? So I'd suggest you sending something to EU/UK to test it, you might be pleased to find there's less trouble than you thought! Anyway what clocks are you selling? You made me curious.? 73 Hans G0UPL On Wed, Sep 13, 2023 at 5:55?PM Joe WB9SBD <nss@...> wrote:

Re: FedEx invoice for import to UK
开云体育Morning Hans,I know of many many small businesses that just plain stopped selling directly to the EU? and UK, just for this reason. I am even one of them. About 25% of my sales went to these areas. Not any more. They are not paying me to be their Tax collector. I still did sell some to those areas but it was a "Do you have a friend or relative here in the states, or anywhere but the UK or EU that I can ship the clock to. And then you two can figure out how to get it to you" " I won't be shipping directly to the EU or UK anymore" Joe WB9SBD On 9/13/2023 7:32 AM, Hans Summers

Re: FedEx invoice for import to UK
Hi Joe TAX! VAT or what in US you would call, sales tax! Since US doesn't seem to care ever about imports, there is no sales tax collected on these small imports to US. So no US recipients have ever experienced this issue. We should be grateful for that at least and pray US doesn't follow EU/UK down the pipes.? 73 Hans G0UPL On Wed, Sep 13, 2023 at 5:41?PM Joe WB9SBD <nss@...> wrote:

Re: QCX+: Noise heard touching trimpot during alignment
This isn't "normal" in my experience. Does it make the noise when touched with an insulated tool as well, or just when touching with a metallic screwdriver? Regardless of that, are you able to make the adjustment and afterwards is it seeming to receive normally without noise? If that is all true, then you probably don't need to worry about it. But if that pot is noisy all the time or when you move the?rig around, then it's either a cold solder joint (most common issue) or a bad pot (not common. I've not seen one yet after over 125 QCX repairs). Good luck ... 73 .. .Ron On Tue, Sep 12, 2023 at 10:23?PM Cosmos <cameron@...> wrote: Hello, |
Re: #qmx Antenna Tuner Can Kill PAs

Guys:
The high transient SWR only lasts for a second or two.? Assuming these transients cause high power dissipation in a BS170.? The chip inside the plastic transistor case may rapidly heat and die meanwhile the thermal capacity of the case may slow its temperature rise.? Extra external heat sinking for this possible failure mode may not help even if it helps for continuous high power operation. Unfortunately: 1) We cannot do a transient thermal model because there appears to be no useful published thermal data on the BS170. - This use of the BS170 is not what it was intended for. 2) Secondly detail Spice model for the PA Stage and LPF would need to be developed to determine the power transient.? So my recommendation is to be careful in the use of auto tuners.? I believe Hans will incorporate some high SWR protection in future firmware but it will need to be reasonably fast to protect against transients.? I hope Hans will incorporate a Tune Mode at ~1/3 power by commanding Q507 to lower the TX voltage to ~6.5V |

Hi Ted
I am all for research and experimentation, that is basically what being a ham is all about. But there has to some numbers else it doesn't mean anything and it will just scare people off. The temperature differences shown on the imaging camera used might be just a few degrees, we really don't know. It appears the current consumption of the QMX is very similar to the QCX so I am finding hard to understand what the goal is here. 73s Ted 2E0THH? ?? |

QUESTION:
Where does the heat get radiated or conducted to? If the unit is cased and there is no air flow the internal case temp is the limiting factor. -- Allison ------------------ Post online only,? direct email will go to a bit bucket. |

Ted
I don't think that he has quantification to the fullest extent, though I respect his interest in researching the actual dynamics involved.? I would like to see someone do two things: demonstrate [with a thermal camera] that heat is NOT transferring to the bottom plane because the copper heat sink surface is in the way, i.e. blocking heat from continuing on to the circuit board plane (good luck with that), and, demonstrate with that camera that the flap of the heat sink is no cooler than the transistors that it is supposed to help out.??
As to the first part, the original model is for the thin, copper trace plating to act as a heat sink. The only place that sheeting can conduct the heat is either laterally to the next uncovered, top open space (much of which rests beneath or adjacent to that supposedly very hot coil), or, to the non-conductive circuit board material to which it is adhered by glue. Are we to suppose that this copper tracing that's blocked on one side, far thinner than the added copper heat sink, and, nestled underneath another heat source, is MORE effective at removing BS170 heat than is a thicker sheet of copper added to that same original plan??? We have a FLIR camera at work that can see off-gassing from petroleum tanker lightering and propane tank leaks.? I'll see if I can borrow it.? K3RTA |
Re: FedEx invoice for import to UK
Hi Chris, Peter, all A couple of years ago, mid Covid19, EU changed the rules, eliminating import VAT minimum value thresholds. Prior to that, low value packages were not taxed (15 euro or less). Now, EVERYTHING is taxable, even if I send you one plastic nut its value will be taxable.? At the same (or similar) time they implemented rules that foreign sellers should collect tax on their behalf, at point?of sale, and make tax declarations to the EU governments. This is completely impractical for a small business. So apparently (though it did not seem so at the time), foreign?sellers who don't have the resources to be able to do this tax collector role for the EU governments, can still send things the old way and have the import tax charged at point of entry.? Furthermore, although you may point out that UK is no longer EU since "Brexit", the UK did also choose to follow the same rules as EU on this. Presumably as it had been already planned somewhat pre-Brexit or perhaps because the UK government also thought it was a good idea.? Accordingly since I do not live inside EU/UK, and since I do not therefore even cast a vote involving the election of these morons who love taxing the hell out of everything that moves (and quite a lot that doesn't), all QRP Labs shipments to EU/UK are theoretically subject to import VAT. The import VAT is the responsibility of the purchaser, including that in many cases the cargo company (whether regular post office or TNT/FedEx courier) will also charge an administration fee.? Two things do mitigate the damage or at least tend to do so: Firstly in many EU countries and UK, the government still don't have the resources to deal with import VAT taxation on all small packages even of low value. The Germans are super-efficient and manage it. But many countries do not. Therefore in many cases there is nothing to pay, no VAT.? Secondly, QRP Labs' shipping office have been known, of course on rare occasions, to make errors on the valuation declaration, and in these rare cases, the import VAT therefore due is of course much lower anyway; and normally the import VAT?+ admin fee is anyway much less than would have been taken in a point-of-sale scenario.? The latter was the case in both Peter's and Chris' cases; I am not sure why Peter's bill was high.? 73 Hans G0UPL On Wed, Sep 13, 2023 at 1:00?PM Peter OM4AEI <om4aei@...> wrote: Lucky you.

Back in my chip design days there were "receivers", ie. input circuits, and "drivers", ie. output circuits. The GPIO was not a thing yet. Of course, even back then we sought to avoid typos! Thanks again, JZ On Wed, Sep 13, 2023 at 7:48?AM Hans Summers <hans.summers@...> wrote:
