I have used the iphone app and it is much, not amazing, but better. It clearly identifies the tones, but the decode is almost always off with storng signals and does nothing for anything in the weak signal range. I do not suggest you buy this app. I would love to get my $20 back.

This is a nice app to decode CW for the mac but unfortunately you canot use the USB audio Codec from the radio to bring in the audio. New radios have USB audo and this app woud be much better with using the radios digital audio.

I have it using the audio interface of my Icom IC-7300. Decodes really well. Squelch works just as expected.

Paying the offering price for an App Store product implird s lrbrl og vspsbility this product fails to deliver for me. I found it impossible to capture anything like both sides of a QSO with good clear signals. It does fairly well with keyboard-generated code, but any slight variation in receive frequency of spacing and it requires as much interpretation of the display as it did the code. I would have had lower expectio if it was %0.99 but at $20 it should probably be updated to this years capabilities.

On a mac I used sound input to Sunflower(64ch) (Free), then output sound to SoundSource (Free) by Rogue Amoeba, then Pass-Through SoundSource to Headphones(or Speakers) to hear what is being passed to SoundSource. The app works fantastic if it is set up correctly.

With a computer generated audio recording play back to microphone of adjacent computer, this application failed to correctly interpret any of the alphabet. However, same recording played back to same computer running http version of competing application successfully interpreted more than 99% of morse code. I was hoping for a mobile application to do the same.

Hi to all hams that read these reviews. I bought the CW reader today and had trouble with it reading from my external speaker of the Yaesu FT 767 GX. But when I hooked up a wire from the external speaker to the MAC mike in jack it started to decode. A few other tweeks and away it went. It has to be a pretty strong signal with a minimum of QRM with the filter on. I m glad I bought this software at a mere 19.99 it works better than Multimode Cocoa and costs one fourth the price to boot… Give it a try even after reading some of the negative reviews Dont know what there problem was but it works for me…73

Have morse decoder on both my phone and Mac Mini - if you set it up right it works great - even had it on while Koch Trainer was running and HotPaw copied letter for letter. Thanks for this great resource — using it with an MFJ-557 straight key/speaker (I’m old-fashioned) and external mic — fun, would recommend.

At first I thought I’d just wasted my money, but read on: Basically the trick seems to be to use an external microphone and don’t have your receiver volume too loud. I also suspect the internal fan vibrations on a Macbook gets picked up and messes up the Morse Decoder’s hearing. When I first got it, All I got were garbage words and miscellaneous letters. I messed with all the settings, and nothing seemed to work. It changed from 10 WPM to 150 and back every few seconds, while the iOS version on my iPhone says 30 WPM, and decodes fine from the same audio stream. I could hear the code clearly from my receiver, and make out the characters, and so could my iPhone and iPad Morse Decoder, when held up to the same speaker. Why wouldn't the Mac version work on my MacBook? Then I read the review written “by CW OP for 30+ years”, (here with the reviews you’re reading now) and adjusted my external microphone’s input volume to 25%, and things started to work. This seems to be the trick: Get some kind of EXTERNAL microphone, go to your Mac’s Control Panel, and do the following: 1.) Click on the Speaker icon (Sound). 2.) Select “Input” at the top. 3.) Select whatever external microphone you have (mine is a Logitech Camera). 4.) Move the Input volume setting to just below 25%. 5.) Place the external microphone about 6 inches from your reciever’s speaker and adjust the reciever’s volume so that you can just make out the CW signal with your ears from where you are sitting next to it. 6.) Start up Morse Decoder and see how it does. Having both Squelch and AGC enabled help for me. Also, once the Auto WPM zero’s in on the speed, you may want to go manual and move the number up or down by a number or two. That really helped, as a last step. If you’re willing to do all these things, you’ll find that it really does work pretty well. So, you may wonder why it costs so much, when you have to work so hard to make it work? I’d guess because alot of work went into getting the software where it is, with all these functions. I’d also guess the targed audience is supposed to be Ham operators who are accustomed to tweaking things to make them work. Have Fun!

Purchased and tried for several days. Will not decode clean computer generated code from ARRL. Well it did decode E E E E E E ? ? ? ? ?. This software definitely needs works.
