#Fldigi and cw operation manual#

I'm going to download the manual and also check out any Icom 746 threads that talk about digital signal reception. I wish a ham with an Icom 746 transceiver like yours would chime in and help us out here. What am I missing? It must be something but I'm not getting anywhere. From there, I try to match the protocol with the bandwidth. Then, I reference the website page that has all the audio samples to find something that sounds similar and a waterfall that looks somewhat the same.

How much bandwidth is the signal using? Is it taking up 50 or 60 hz? Or is it spread out over 200 or 300 hz? Is it a single trace, or is the signal composed of more than one trace?

Then fire up the digital modes software and check out the waterfall. Seriously though, when trying to lock onto a (non CW) data mode signal, in what order are things done? For instance, the first would be to tune the radio to get as strong a signal as I can get. Still trying to figure out what 5NN is for. Oh well that's just dandy! So I have the CW Decoding software, (thanks to some seriously dedicated ham operator folks who make it free), and now what I need is decoding software to translate the decoded CW.ĭoes it end somewhere? LOL I'm going to have to print out a cheat sheet for all their abbreviations. are there specific radio filtering settings that must be used? I must have some setting incorrect somewhere. I just can't figure out why I'm not able to decode them. But after reviewing all the samples, I think it was the MFSK. Obviously I knew some protocols wouldn't work as the signal wasn't even close. Tried the MultiPSK and FLDigi, and every protocol I could find. I did everything I could do to decode these and never even came close. Sometimes, there were three or four simultaneously. and the one in the middle seemed to do most of the transmitting. Some were higher pitched on the right side of the waterfall, some at a lower pitch on the left side. There seemed to be some kind of conversation going on as I sometimes had 3 or 4 traces on the waterfall at once and all at different frequencies. It kind of sounded like one of the higher bandwidth modes like MFSK16 but the trace was only around 60hz wide like a BPSK31. Last night, somewhere on the lower side of the 40 meter band, I think I found an MFSK signal that sounded almost exactly like what is demonstrated on this website: I downloaded a couple of websites that provide examples of various data modes, provide a waterfall example, and even a short sound clip of each mode. There are no dumb questions when you are truly trying to learn something.ħ3 (best wishes in ham lingo), Dave K4EET Be sure to look up some of the history and technical aspects of the mode while you are at it to give you a well-rounded understanding of each mode (why it was first developed, what/when it is best used for, etc.).Įnjoy your travels and don't hesitate to ask questions if needed. While those modes are not really complete conversations like CW, RTTY and PSK31 would be, they are known for getting a minimal amount of information through quickly in a narrow bandwidth under less than optimal radio frequency (RF) conditions.īut like what was said before, focus on a single mode and perfect identifying and copying that mode before moving on to the next. You might also be interested in WSJT-X ( ) by Joe Taylor, K1JT, who developed FT-8 among other protocols like JT9 and JT65. Keep at it and you'll be an expert in no time.įLDigi is a good program. Yup, CW ops have their own shorthand to keep actual words per minute (WPM) higher. I got a chuckle out of your post and I'm still giggling.
