Hello SWLers,

Hope you don’t mind but I would like to introduce to you a Digital Ham Radio Group that is FREE to join and SWLers are welcome to join and participate.

As a longtime SWLer back some 40 years I was always interested in different activities and different modes to listen in on to learn more.  The modes of AM, SSB, and CW most common modes but today if these are the only modes a SWLer is listening in on you are missing a lot more activity that are digital modes – those of RTTY, PSK31/63/125, MFSK, Olivia, Contestia, FeldHell, JT65, WSPR, ROS, Domino, and many more.  Nice thing about the digital modes is almost any SWL receiver that does SSB can be used along with a PC soundcard and FREE software (please note most all digital modes are in USB).  It is as simple as downloading the software, making or purchasing a short jumper that will plug into your external sound jack on your receiver to your pc’s soundcard in/mic jack (most can even be copied and decoded by having the receiver close to your pc’s mic or using an external pc mic positioned next to your receiver’s speaker).

Some Links for examples of listening in on digital modes:

For beginner users you might want to start with a simple program called DIGIPAN that will decode the most popular digital mode of BPSK31 or PSK31…go here to download:

Try Some Multi-Mode Digital Software (Most have RSID):

What is RSID:

If RSID is not being use please reference this link from FLDIGI on the Sight & Sounds of different digital modes that might help you determine what mode is being heard/seen on your waterfall:

Most active have already mastered all of this but for some if you have not tried it please give it a try and have fun SWLing.

Thanks

Like the 6-mtr band, 30-mtrs is mighty lonely most of the time!! Too bad, cuz it has the potential of world-wide DX most any day!
