Heard all the IV stations on 518 and learned that "Within the U.S., there are no current plans to broadcast NAVTEX on the alternate designated frequencies of 490 or 4209.5 kHz."  On 6314 and up it's not called NAVTEX but is referred to as USCG HF SITOR (NBDP)  and I have logged many of those on 6-12 MHz.  I was listening overnight on 4209.5 and a lot of Spanish stuff which I have not been able to figure out the callsign of yet. Nothing on 4210 yet.

It looks like it is easy to convert the Grove-UART connector to act as GPIO. Some typos in the examples on webpages is thwarting me at the moment.

I am using this module to test Grove with and figure I can mod one to use as a relay driver http://wiki.seeed.cc/Grove-Chainable_RGB_LED/
