Barry, thank you for confirming what I suspected....that the MTH app only displays in portrait mode. Knowing that before I make equipment purchases will aid in making decisions and minimize buyer's remorse. I am trying to do my research before I buy, but expect the portrait only display will be OK.
I did purchase both of your most recent books {DCS Companion 3rd edition, and WiFi Companion 2nd edition} and am very impressed by how detailed and helpful they are.
Regards, Paul
