Spanish comms and one is using a "calltone" type signal at the beginning of transmission. Anyone?

I got them on 4880 now w/ roger beeps each time they keyed up. Probably same as your guys.

I just checked my logs and had them on Oct 21, 2010 on 4888.

Still ongoing activity on 4880 w/ clear voice comms and data transmissions. Any idea as to the data mode?

Got it here but it's extremely weak on the voice side. The data just sounds like really fast RTTY.

Back into voice mode. OM station calling Durango.

I think it may be Mexican Navy. Romeo Delta calling Durango "uno cinco uno"
There is the ARM Durango PO-151 which could be the station.
ARM Durango - Wikipedia, the free encyclopedia

I also heard a guy whistling.. don't know if related to the stations or not. Our friend hfdxer may have to help translate

Pretty interesting nevertheless.

The data actually sounds more like ANDVT. But there is a new digital mode that sounds like a hybrid of ANDVT and DRM.
