![]() ![]() ![]() (2) The manual tells you to adjust the "Level" and "Tone" buttons if necessary. (1) There are times that when you play memory 1, memory 2 will come in right behind it without you telling it to do that. ![]() Here are the comments I made to myself during the detailed review. I stand by my earlier comments in that in does indeed power in the CW signal. I have since gone through the product with a fine toothed comb and also page by page through the operators manual. I gave this product a preliminary review earlier. Just look for someone without the patience to set it up correctly. It's a keeper in my book, and if you can buy one used at a better price than new, buy it. The result? 90-100% decoding barring QSB and sloppy fists. My radio is set to pass a 700hz CW tone, I use a narrower filter once I have the signal tuned in, and use noise reduction. Properly adjusting input level, tuning to the proper CW tone in Hz which the decoder is looking for, using a narrower receiver filter, and not using noise reduction if available. My guess is that the folks that hear CW signals, but complain it won't decode, or decodes random letters are failing to do a few things. I honestly believe all of the low ratings here are due to user error. If you have a noise reduction or DSP on your radio, use it. The tone of the CW signal must match the tone you have chosen the decoder to decode. Input volume needs to be carefully adjusted to provide adequate signal, but not so much that you begin decoding noise. The unit does a wonderful job of decoding CW, even very weak signals. Eventually, I will probably use it to it's full potential, but for now, I will use it strictly as a reader to supplement my ear, and save on paper and pencils. I picked it up used for a reasonable price. I have a serial port on my computer connected to the serial port in jack on the 464, but have not tried to use this with any software yet.want to get the basics working better first. I have the pitch set correctly on both the radio and the MFJ unit (700Hz) as recommended. No amount of tweaking the radio volume and the level control on the '464 makes it read reliably. Even with a strong signal, it reads the hash and trash.lots of Es and Ts. I'm in an urban area, so the noise floor is anywhere from S3 to S7 depending on the band. The biggest issue is the fact that it really doesn't read code very well if you have anything other than a very low noise floor. "Key out" from the '464 to rear key-in jack on the radio. I am using a PC keyboard, which is plugged into the keyboard jack on the back of the '464. Rear line-out jack into "radio in" jack on the '464, then external speaker jack on the 464 to external speaker. I have finally gotten this device configured with my Yaesu FTDX-3000. ![]()
