SCAMP's protocol specification is available in http://www.winlink.org/Presentations/SCAMPspec.pdf
There is also an article on SCAMP by its author, Rick KN6KB, in the proceedings of the 23rd ARRL and TAPR Digital Communications Conference. Here's the abstract: Digital modes enjoy increasing popularity and performance thanks to a better understanding of Digital Signal Processing (DSP) and continual improvement in the performance of modern computers, sound cards, and operating systems. SCAMP is a new experimental "wide-band" (2 KHz) digital sound card message protocol suitable for HF. SCAMP leverages the work by Barry Sanderson, KB9VAK and employs an ARQ "wrapper" around Barry's Redundant Digital File Transfer (RDFT) scheme to provide the error-free automatic operation necessary for today's modern digital message systems. This paper documents work in process developing and testing a new sound card mode that promises Pactor- like performance for HF channel transmission. Key words: RDFT, HDSSTV, Pactor, MT63, PSK-31, Winlink, DIGTRX, Sound Card Modes, Pipelining. These proceedings can be purchased via http://tapr.org/pub_dcc23.html 73, Dave, AA6YQ
