For those of you practicing with your FLDIGI, you’ll be able to tune in this weekend to Voice of America.  They’re broadcasting on shortwave this weekend, mixing voice and digital communications.  There will be four broadcasts lasting 30 minutes each.  Get your laptop out and fire up your digital commo software.  Remember, you don’t have to be a ham operator to use these modes when simply receiving (listening/monitoring).  This will be great practice for all of us.  Below is the email I received from an AmRRON operator in occupied America.

Voice of America


Below is a paste of the latest email regarding ‘testing’ of Fldigi on the AM Shortwave Bands.

They have been testing this for a while now and it works great. This weekend the transmissions will originate in the US so any in the Redoubt area would likely hear.

Follow the link for information on modes. Unless those receiving have considerable practice with Fldigi they would likely be best to monitor for ONE of the ‘multiple’ modes. MFSK32 will be a small picture, a bit different than text but automatic in that mode. There will be more of this in the future.



VOA Radiogram, combining voice with digital text modes via shortwave broadcast, will “soft launch” this weekend.

The half-hour program will be transmitted four times during the weekend via the BBG/IBB/VOA Edward R. Murrow transmitting station in North Carolina.
