[digitalradio] Re: CMSK63
Hi folks, There seems to be a fair bit of misinformation around regarding the new CMSK mode for LF/MF. I recommend you go back to my web site, read all about it, download the latest version, then READ THE HELP FILE CAREFULLY. www.qsl/net/zl1bpu/CMSK/cmsk.htm The mode is not intended for HF, and I won't answer questions regarding its use there (use MFSK16 or DominoEX please!), but I am willing to respond to questions about its use on 2200, 600 or 160m. Pay particular attention to getting the sampling rate correct, especially on CMSK8, which is intended for beacon rather than QSO applications. You can expect it to take a while to get the tuning correct, and for text to appear, since the CMSK8 mode has long latency. This is a price you pay for narrow bandwidth and high sensitivity. Once documentation is complete, we'll offer the mode for inclusion in multi-mode software such as FLDIGI and HRD, but for now the features may seem a bit limited, and that's on purpose. 73, Murray ZL1BPU Co-designer, CMSK

I suggest you read the help file. All your points are answered there. Download the latest version. 73, Murray ZL1BPU --- In digitalradio@yahoogroups.com, my_call_is_ac4m kf4...@... wrote: I will be on 80m tonight using CMSK63 then switching to 31 after contact just to see for myself how well this mode does under noisy conditions I will be active on 3.587 tone frequency at 0100z but I have a few question does his software have Macro commands like other software?

No luck again today. Could be that it is an issue of the poor propagation caused by the present sun wind and it's impact on the magnetic field of the earth. I will try again in CMSK next week when the sun wind has calmed down as the propagation forecast is telling us. Thanks for the report from W9 even though it was too weak for decoding.

[digitalradio] Re: CMSK63
Well it seems the software at least in the beta version has a few bugs. like the buffer is not being dumped like it should and then after hitting f10 you might decide to erase what you want to send it seems afterwards it will not send anything or at least it is not showing you it is being sent , I also notice you can not add any words while transmitting like you forgot to put in a word type of thing when typing it seems to just skip right over it. the S/N seems to be very wrong on measurement -55 DB hmmm I don't think so , Hopefully the bugs will be addressed and fixed.
