If you are on a cruise ship and you visit different countries, please be careful if you arrive in a different port, because the government can pick different frequency for there country.
dPMR446 uses FDMA ( Frequency Devision Multiple Access) upto 32 Real Channels! DMR is Wasteful in Tire 1 mode, Business use TDMA Tire2 mode on Licenced Frequencies with a Bace Station
Not keen on these hytera does a similar looking radio which has analogue and digital antannae on the hytera is excellent on analogue and digital modes it also charges via mini usb but this is located on the side the radio has solid metal surroundings and a carrying case it slides into on analogue I've had 4 miles no problem and digital 3 miles much greater ranges achieved hill top to hill top digital 25 miles analogue 50 miles sound and mic quality from hytera radios are superb obviously much more expensive than the radiodditys which look cheap and nasty.definately not one I would personally invest money into.
@@ReviewTechTV my hyteras are only 0.5 watts but the mini antannae pulls signals in perfectly don't get me wrong the radiodditys are still good for the price and good on digital would have been intresting to see the peak distance of digital.but definately let down by analogue.

Generally radios are either licence free, or require a licence, so please be mindful of that.
If you are on a cruise ship and you visit different countries, please be careful if you arrive in a different port, because the government can pick different frequency for there country.
For Europe, PMR446 should be fine, however, using a two-way radio on a cruise ship may be tricky if it is big and the metal absorbs all the signals.
@@ReviewTechTV at Sea in international waters if you ask Permission you maybe allowed to use them!

Keep in mind I did only use 0,5 watts, obviously with 2 watts it would have performed better.

Do you mean 170USD+ Hytera PD505LF ? I don't see any other model that has PMR and DMR and is license free in EU.
DMR always sounds nasty
Yeap, unfortuntly analog sounds better.
