These values are, of course, unconfirmed. The same would be true for Crystal Palace at 10kW, but on channel E31, or 554000000, no offset. barry bouwsma -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
