Most websites about digital radio or television are tailored to a specific system, or filter their content according to the location of the reader. Digicomparison assumes that you are interested, potentially, in all systems, or wish to know something about the system in use in another territory. You will also find guidance about the systems in use in particular countries. The companion website to this one is Wohnort's DAB Ensembles Worldwide. If it is DAB that interests you, then dare we say you won't find more comprehensive information about broadcasts around the world anywhere else.
When comparing internet retailers, remember to include the cost of delivery in your calculations.
Retailers with low headline prices can often have higher delivery charges. Comparison websites usually list the lowest headline price first, but the best deal may be lower down the list.
I'd be grateful to receive updates and corrections.
