OT: Package transit time to the UK?

Rose
Does anyone have a feel for the time a package
sent via air mail to the UK from the US takes to get
through the two postal / customs systems and be
delivered?

I have one that was shipped on 03 October and
has not been received by my customer.

73!

Should have been here by now Rose, I think 3 weeks is the longest I've waited.
Air mail is usually next day to the destination country, maybe 2 days depending upon timing.
Don't know about US side, but probably only a couple of days and then I'd say 5-10 days over here. So on average, 2 weeks.

CFL

Jack Smith-6
The CFL's I've analyzed and disassembled have small switching power
supplies, usually running around 40-50 KHz.

If you are a VLF/LF listener, you can see the emitted signals up through
several hundred KHz. Many sidebands can be observed, at multiples of 60
Hz from the central frequency (which is unstable).

Usually, though, not much can be heard about 1 or 2 MHz if your antenna
is separated by a few tens of feet from the lamp.

If you have a defective CFL, disassembling it can be educational. First,
you will see many components stressed at or above their maximum ratings.
I've seen some with the filter caps operated with voltage above the
maximum rating.

Second, it's not uncommon to see the PCB with holes and traces for EMI
filtering, but the parts are not installed. I assume that the parts are
installed in some prototypes to meet EMI specifications and then are
omitted to save money.  I don't believe the CE approval markings mean
anything to the Chinese manufacturers.

Jack,

I believe some (not all!) Chinese companies might think that CE means
Chinese Export!
