Gary,

 

 

Using the  Dutch  web-sdr  about  400  miles  , ROS decoded this  ......  2230  looks like the  full text string ? no  audio  from the  speaker or as far as I could  see  no trace on the  waterfall  .......

LF,

Not able to reply to any calls from now but the beacon will continue until about 2300utc.

I will resume tests tomorrow (Friday) night & increase power for greater distance.

Hi LF,

I am increasing the PTT loop timer to provide a 5 minute increment of the beacon.

This will give operators lots of time to create a reply or call. My beacon will stop & notify me if a reply or call is made.
