I'm not surprised about the OP's negative comment. In early 2014 I wrote an article asking why manufacturers like Yaesu, Icom and Kenwood routinely exclude the 220 mhz band in multi-band radios like the FT - 897/857 , Icom 706 and other popular multi-mode, multi-mode rigs...
I was rather shocked when hams actually defended the manufacturers saying that no one really uses that band. Really?
So lets give the band to commercial interests then, after all 'no one uses the band'. While we are at it, why not give the 900 Mhz ham band to commercial interests. After all no is using that band either ....we don't need that many bands...right?
To date no manufacturer, not a single one, not even the Chinese are making an multi-mode 220 Mhz rig.
http://www.eham.net/articles/31298 No one is producing a 900 Mhz multi-mode rig either.
So the topic is about the 630/2200 meter bands, why discuss 220 Mhz?
Well, using that ill conceived logic for 220 Mhz....since no used the 630 and 2200 meter bands (before they became legal). Perhaps we should have given that to commercial interests? After all hams are not interested in 630/2200 meters ....because ...
"but why do we need two more ham bands"
Using the OP's logic...perhaps the WARC bands should have gone to the Maritime Mobile Service instead of radio amateurs because there were no amateur radio operators were using the bands before it became legal to use them. After all we already had 80/40/20 and 15 meters. And
