Have had Dish since primestar. Just had Dish activate local channels. Have 2 recievers, Say Pro 508d & VIP 211k. 211k recieves local channels, 508d will not. Have tried everything Dish suggests, even bought a new 508d, nothing, they have no idea what's the matter. Heard from friend that the 508, 301 and others will not get locals because of old tech, mst upgrade to 622. any ideas?
