Narrow Band Emergency Messaging System an integrated suite of programs that can be used for both emergency communications and recreational operations. Modem program that supports most of the peer-to-peer (live keyboard) digital modes used on the amateur radio bands. The software also controls the radio by means of another connection, typically a serial port.įldigi, Fast Light Digital Modem Application, pronounced "F L digi", is a cross-platform Fldigi operates (as does most similar software) in conjunction with a conventional HF SSB radio transceiver, and uses the PC sound card as the main means of input from the radio.

However, in the face of selective fading and QRM, the assumption of symmetry proved to be wrong.The flip_smallest_bit code was written with the assumption that the discriminator has equal weights for mark and space, that we are equally likely to get things wrong in each direction, and that flipping the bit with the smallest absolute value is likely to get us what might have been transmitted.make single bit flip correction guess a little smarter.adjust tracking filter constants to improve power detection.Fix cosmetic issues reported by Bob, VK2YQA.
