G'day! Is there any difference between FTDX-3000 and FTDX-3000D. They all seem to be branded FTDX-3000 on the radio itself, but I've seen FTDX-3000D printed on the packaging. Some dealers advertise them as 3000, some others as 3000D ... go figure. Was there a "D" revision since the first 3000 model came out? I saw one of the dealers here who is selling them stating the following: Major update on FTDX-3000D radios sold by us from July 2015. I emailed them to ask what's updated but haven't received the reply yet. Also, there seem to be D, DM and DS versions (possibly only in Japan), does anyone know the difference between them?
