I have some  medical problems and haven't been able to do code. I really want to do QRP CW. Which are the best programs for encoding/decoding CW by computer, both pay and freeware.

CWGET and CWTYPE from DXSOFT are pretty good. Also programs like MIXW include CW. The problem with **ALL** cw copy programs (that I have ever seen) is that they work really well when the cw is computer generated and the QRM and QRN are low. For example, I can usually copy the W1AW broadcasts nearly 100% but much of the hand sent CW on the bands is at best run together and at worst full of incorrect charaters created by static crashes, etc.

The other thing to consider for transmit is that if you are using a CW only QRP radio then you must have a program that generates CW keying via a serial port control line rather than CW audio tones via the sound card. You can use the sound card for receive.

There are also some hardware solutions (MFJ and others) that give you a LCD display and a computer keyboard if you are thinking portable operation or don't want to use a computer for some other reason.

Thanks. I have a interface from Tigertronic that will handle the computer connection issues. I also had a chance to connect my pocket pc with digipocket to someones K2 at a ham weekend. He thought it ran pretty well. I am sure what you say is true about the hand generated code versus machine and the noise factor.

MRP40 is an excellent decoder! I used the trial version and liked it so much I purchased a copy of it. I used it extensively when learning CW and still run it when I am tuning around the CW bands. It is a good weak signal decoding program. Not cheap, but a good piece of software.

Ham Radio Deluxe with its companion Digital Master 780 does a good job decoding CW.  It's freeware.  I would rate it on par with MixW, but not as good as CWGet.

Haven't tried using it to send, but it interfaces with the K1EL WinKeyer which is a very popular computer keyer.
