Ive been using mine for 39 years never fails and it doesnt require batteries just AMAZING Click to expand.It doesnt seem to be all that accurate unless the sender is using near perfect spacing which seems to be somewhat rare according to this program.
I use it mostly for its audio spectrum display, that is pretty cool and acts like a spectrum analzyer limited to the bandpass of the filter width of your receiver. It cant correct for a truly horrific fist, but it does so better than any other program Ive seen. Dave K3DCW. The interface is mostly the same for all of them but some are definitely better than others. I like EhoCW because of the Iambic paddle capabilities, however it uses a very slow decode algorithm so it copies rather far behind. If it starts to mess up, you are so far behind the received code that you have no hope of catching up. I find that DM780 and Fldigi are about the same in CW decoding. Unless it is copying machine sent code they both seem to put far too many spaces between characters. With all the abbreviations that CW operators use, it often tough to determine whether it is decoding correctly or not. I havent tried CWGet or MRP yet, but I wll have to try them out. For me, the best interface for CW is a program written in 1988 by Kevin Schmidt W9CF. The program is written in C, compiles with Turbo C, and runs in the DOS mode. The interface, TX and RX, to the radio is through a serial port. TX is rather simple, but RX requires a hardware filter that converts the audio to zeros and ones. I built a interface that filters and converts the audio directly to zeros and ones, which then feeds directly into the serial port. The filter is set to match the TX offset for most of my rigs. Radio Decoder Software Software On AnI run the software on an old Altura 486 Sub-Note laptop which is running Windows 3.1. I have put it up against DM780 and Fldigi and it beats them every time. The software only takes two or three characters to initially zoom in on the code speed and then tracks the incomming code. Since it depends on the last couple of characters, to tell the difference between a dot or dash, it compensates easily for speed changes. I keep on trying to replace it with something more up to date, but I havent found anything yet. Some great features are IF shift, NB, noise reduction, notch filter, etc. Ive been using mine for 39 years never fails and it doesnt require batteries just AMAZING.
