CW decoding...???

[Shortwavewave]

Hello yall,
lately ive been trying to decode CW with Multipsk and R75, i just dont have any luck with anything all i keep getting is a bunch of EEEEE's and IIIII's

Can some one please tell me what im doing wrong or what to do

THank you

Sure!

A = " . ___ "
B = " ___ . . . "
C = " ___ . ____ . "

Etc ...

Can't help you specifically, but if the guy isn't sending 'perfect' CW , sometimes its hard to get a good decode. The brain is the best method ... you can usually copy some pretty rotten sending once you get the hang of it.

Hat's off to you for trying and keep at it!!

I've never had much luck decoding cw by computer. I prefer to use wetware.

It willl only work with other machine generated code and will have to be a clear signal to use a computer to decode it.

Try some of the commercial cw sites that generate by computer. That way you can find out if the sender is at fault or the unit.

Commercial CW? Who's still doing that? I haven't heard cw outside of the ham bands in at least a few years.

This is not entirely true, I copy code sent from strait keys, and paddles with auto keyers every day, the code does not have to be machine generated. I use MultiPSK and MixW to keep a record of my CW contacts. You are surely correct in saying it needs to be a clear signal, and have good character formation, because I am new and can not copy bad CW the computer is able to copy any QSO I have had. Give mixW a try first it is much easier to use then Multipsk as there are so many settings and buttons who knows what could be wrong. A good way to test your software is to decode W1AW CW practice sessions. You can find the schedule on the ARRL website.

I've used CWGet with good results. Maybe it's not a finicky. Might give it a try.

I think I used that before, is it the one with the lines you move up and down to the level of the signal? I didn't have real good luck with that, only on very well sent and very strong code. MixW and MultiPSK work much better for me, I was actually quite surprised at how well they did. As someone stated above, the best way is to learn the code, then you don't need the software! It's easier then it sounds

Ive tryed to learn it but i just dont have any luck

It just doesnt click with me, like it does with some people

When I first started driving a manual transmission it didn't go too well either. Stick with it boys!

Scott: Thats an amazing pic of the refuelling op on your 'QRZ' post..........If it may be said, what altitude and air speed would those craft be flying at during that refueling procedure?? TIA.

Oh now your going to make me think.....air speed I have no idea, they are not controlled while on the track, just going in and coming I would guess that it is dependent on the type of aircraft being refueled. We were on track 455 which has a block altitude of FL250-270, so 25,000-27,000 feet. Here is a link to all the frequencies used, and a map of all the tracks and their block altitudes. They are very active, If you just put the primary frequency in for any track near you and scan them you will hear some activity shortly. Don't be surprised at how far away you can hear these.

I had this publication in the tower I worked in while I was in the military, I took it, my Icom IC-20 and a set of headphones with me on the refueling mission and listened to all the communications. When an aircraft is hooked to the boom of the refueler, they can use an intercom, but they are usually on the radio regardless. Most of what is done is practice so they are on and off the boom quickly and back on the radios. It was a really neat experience, PM me with your email address and I'll send you the full sized pictures, they look awesome!

Come of the hams send with the computer, especially during contests. I bet 90% of contest CW is computer generated. Basically you type in the call of the guy you want to work, hit return, and the computer takes over.

Somebody beat me to it, so I'll second it-- W1AW CW practice or bulletins would be good to try to copy. Their RTTY bulletin is about the only thing I've ever copied on RTTY with Skysweep.

 

[Reloader]

I was referring to some of the CW communications such as the French, Russian, and other countries in the 4, 8,12, 16 MHZ . I used the wrong phrase. There are still some out there and receivable. You can get the frequencies from a variety of sites, such as the Klingenfuss website, as well as Monitoring Times.

You need to join the ENIGMA group. You would probably be surprised at the amount of morse code that is bounced around on different freqs. These are generally one way communications broadcasting numbers or the occasional alpha and numeric siganls.

I am aware of the numbers stations sending cw, but my comment was more in reference to commercial operation where the messages being sent are actually comprehensible. I've heard the 5 letter groups being sent, but don't pay much attention, since all one can learn from them is that they exist.
