NOAA Navigation charts in Oruxmaps?

[schweizer]

Hello,

I'm a long time user of Oruxmaps, from earlier days when Google Maps was included.  What a great app!!!  I'm wondering if anyone has a working onlinemapsources entry  for NOAA Navigational charts?   I found an example but it doesn't work.  Thanks for any help!   Marcus

Replying to my own post:  the NOAA charts are now accessible in WMS and WMTS format.  (The old tiles were discontinued.)   I've tried setting up the WMS or WMTS charts in Oruxmaps, but was unsuccessful.  Has anyone else tried?
