That's what I thought too. That's what I'm doing at the moment. The frequency I see as a form of location. Except on the electromagnetic spectrum. > Now, how to encode the frequency?

However it is worth noting that some radio stations are not placed at one frequency, but a range: however the idea doesn't deal with that as it stands. So, bearing in mind my bias towards frequency being a location [albeit a fuzzy one], I'm thinking on the lines of <div class="vcard"> <strong class="fn org">BBC Radio 3</strong> <span class="role">radio station</span> <em class="frequency"> <span class="low">90</span> - <span class="high">92</span> <span class="band">FM</span> </em> </div> I'm ignoring the Hertz units because: 1. As far as I can recall, no one has ever mentioned them while speaking; and 2. the band [FM/UKV, AM, SW, LW, MW] is more important for physically finding the station on a radio. If you DID want to use the units [which from a scientific point of view would be correct] then this could be like this: <div class="vcard"> <b class="fn org">Heart FM (Sussex)</b> <i class="frequency">102.4 <abbr class="unit" title="Megahertz">MHz</abbr> </i> (<abbr title="50.9761;0.2293" class="geo">Eastbourne</abbr>) </div> I do agree that stations are very geography specific, though. But to my thinking, the geo block does not need to be inside the frequency class if the information is contained in a hCard [although it could be]. So for the Sussex Heart FM example, it'd look like this: <div class="vcard"> <b class="fn org">Heart FM (Sussex)</b> <i class="frequency">102.4<span class="band">FM</span></i> <!-- and then you could move the latitude/longitude out into its own section if you like --> (<abbr title="50.9761;0.2293" class="geo">Eastbourne</abbr>) </div> Or more formally: <div class="vcard"> <b class="fn org">Heart Radio in Sussex</b> <i class="frequency"> <span class="low">102.4</span> and <span class="high">103.5</span> <span class="band">FM</span> (<abbr title="50.9761;0.2293" class="geo">Eastbourne</abbr>) </i> </div> What do you think?
