Best CW decoder available  Time owned: more than 12 months
I have been using this program for almost seven years now, ever since MRP38 which was the original DOS based CW program. I have tried a number of alternatives, both other software (CwGet, MixW, etc.), and hardware (Kamtronics, MFJ, etc.). I use it partly as a backup for copying high-speed and noisy CW, as well as providing a good hardcopy automatically of the QSO on my computer for logging purposes. The spectrum display on the computer is also really useful for tuning and zero-beating your rig.

This is definitely, hands-down, absolutely the best available system for CW copy in QRM and poor sending currently available, short of the human ear itself. Your ear will always be best, but MRP comes surprisingly close!

Other software systems typically fail because of QRM, poorly formed CW and/or frequency drift. The decoding algorithms in MRP40 just seem designed much better to handle this. I have found most hardware alternatives to be pretty useless, plus they don't provide a hardcopy of the QSO.

Most negative comments about this software fall into these categories:

1. This is neither freeware nor shareware, and the author protects his Intellectual Property aggressively with a short and unbreakable trial period. Expect to pay for a license and also to pay for software upgrades and when you upgrade your computer.

2. There is only one author and he alone provides all support. I must say, though, that the 2-3 times that I needed technical support over the years, he has always been very responsive and friendly.

3. All CW software requires a fairly fast computer and a good soundcard. Although I am comfortably using a 4-year old Pentium III machine, anything slower really won't work at all well with MRP40, especially the graphics. You will also notice "jerky" CW send if the computer is slow.

4. It only works CW - there again, that is exactly its strong point since most of the value of MRP lies in its specialized CW reading algorithms...

If you are OK with these four main points, I can recommend this software to you unreservedly. It is very good value and performs as well as current technology allows.

See you on 40m / 80m CW !
