It was me. I confused Ellis. I'm sorry!!
Anthony is right (as he got all his info from me just last week!).
Years ago, when the first FlashWizards and PocketWizads were being developed, we did a lot of research to find a relatively uncrowded frequency for our radios here in the US. The less crowded, the better radios work. We choose 344.04MHz as a really "quiet" frequency ... and it still is!
At that time we were not aware of European laws (and neither was Europe as this was before unifying laws, and CE branding, were established). What little we knew of them was that we would have to come out with an Italian-only radio, a German-only radio, a British-only radio, etc. It didn't seem worth our while to pursue.
Since then Europe unified their laws and picked the frequency 433MHz as the one we could use all over Europe. 433 is also available in the US. We had a dilemma! Do we change our US PocketWizard frequency in favor of an intercontinental one BUT make our broad base of existing US customers lose forward compatability? Or do we make different world region frequencies and not have units that were sellable world-wide? And if we did go to 433 in the US could we live with the fact that this is a relatively crowded frequency and thus suffer a performance loss? Eek!
(a clever sleuth will ask, well why didn't you make a unversal one for sale in the US that would work on BOTH frequencies? the answer is cost -- any new US PocketWizard owners would have to pay more for a dual frequency unit that only a few jet-setters would actually use. or the small run of universal ones would cost so much that even the jet-setters couldn't afford it! and the universal one would still be only for the US as 344.04MHz is not a useable frequency in the EC. makes my head spin...)
We decided to go with different world zones. It works for cell phones (though people still get annoyed with that), but we feel we made the best decision we could given the circumstances.
Before CE versions of the PocketWizards were made, folk from overseas areas found "sympathetic" US or Canadian dealers and acquired US PocketWizards.
These PocketWizards, like other radios on the market (Quantum FreeWire
model only excluded), are probably illegal overseas! How illegal you ask? Well, I'm not a lawyer and can only speak from what little I know about US radio laws and from others' experiences. My input here is purely speculative. I have asked a few folk who may know and am awaiting more real answers.
Now the laws of physics are the same the whole planet over (except maybe New Jersey). PocketWizards WILL WORK just fine anywhere on the planet, the only question is legality.
(speculation on laws to follow -- I am not a lawyer)
In the US I believe that if you are using a radio device and it is causing interference then authorities could say, "Stop using that device." Only if you use it again are you breaking the law. This might be true overseas, but I'm not sure.
In practicality I have heard of many folk using US PocketWizards in Europe without incident. The only report of any trouble I've heard about was several years ago when an official at Wimbledon took issue with the big FlashWizards being used. In that light it seems like PocketWizards usually fly under the radar. Please note, I am not condoning breaking the law -- I am merely reporting others' experiences. Other radio slave manufacturers have sold beneath this radar for years.
A WORD OF ADVICE: when traveling betwixt continents (or even domestically) call your PocketWizards, or ANY other slave device, a simple remote control for your camera. Ship it ahead or put it in checked baggage. I personally would not want to explain to airport security, especially now, that this is a remote triggering device, used for setting things off when you're at a distance, that'll work nearly a quarter mile away and in one method of operation makes a terrific flash of light.
Sorry, Richard, but I have not answered your question (this was more for Ellis and Anthony). While I have a ton of experience with PocketWizards (only 2 people on the planet have more) and a fair amount of experience with Quantum products, I shouldn't answer your question as I work for PocketWizard and it is imprudent for me to talk about competitors (at least in comparison for purchase terms) on this forum. I did so in the past and am horribly embarrassed about it.
Oh yeah, the Sekonic Receiver units are in fact PocketWizards in new suits. And MultiMAX/MAX Quad-Triggering is on the upper 16 channels as the lower 16 are reserved for compatibilty with all other PocketWizards.
