I
operate SSB and digital modes, with the emphasis on the latter. My
introduction to BPSK31 happened by building a Small
Wonder Lab PSK 20 qrp rig in January 2007 and I was hooked. With the
appearance of programmes like Digital
Master 780 and Fldigi which
provide easy access to many other modes, including RTTY, it is easy
to experiment with many modes and decide which one suits your operating
style. Of course, WSJT-X has transformed the digital operations of many hams with modes like FT8, etc.
SSB
The links below provide the history and technical descriptions of SSB. Any recent edition of The ARRL Handbook for Radio Communications contains all one needs to know about this mode. See, for example, 9.26ff in the 2006 edition. ++ http://www.hamuniverse.com/ssbinformation.html ++ http://en.wikipedia.org/wiki/Single_sideband ++ http://dj4br.home.t-link.de/ssb1e.htm ++

Digital Modes The links below provide some information about some modes. They are not comprehensive! ARRL's
HF Digital Handbook is a good but somewhat out-of-date introduction.

This site has good coverage of many modes: http://www.qsl.net/wm2u/
++ This article deals specifically with getting on BPSK31: http://www.arrl.org/news/features/2006/08/06/1/ ++ This is Murray Greenman's site which deals with fuzzy modes: http://www.qsl.net/zl1bpu/ ++ This is the site for Joe Taylor, K1JT's neat modes: http://www.physics.princeton.edu/pulsar/K1JT/ ++ Courtesy of Dave Freese, WIHKJ, the author of the Fldigi programme: Sights and Sounds of Digital Signals |
