I built my own serial cable which has a 1/8 mono jack that plugs into the MFJ-464 and a 9 pin serial plug on the other (male I believe) that hooks to a USB to serial converter (with prolific chip windows 10 compatible) from Amazon. My new computer has a serial port and the 9 pin connects directly to the computer without the USB to serial converter. Works great.
This is a New England QRP Club SCAF audio filter kit. I am not sure if it is available anymore but you could find their web site and see if it is. I had to get an aluminum case off of Ebay and make my own case. It works real well. The kit is a little difficult but not bad. I lucked out and had no issues with it. Calibrated it and it was off and running for me. I suppose I ought to demo it on video, but am not sure if they still have the kits or not.
Hi Bruce, What cable are you using to go from the icom 7300 to mfj 464, and where do they plug in to each unit? If you can post a short video it would be much appreciated. I recently bought the mfj 464. The instructions Suck! I even called mfj tech support and they couldn't even tell me what cable I need, or where they get hooked up!! PLEASE HELP ME 👍 DAN M. Maldog
Hi can you post a link where to get the stereo jack plug with single rca as i have looked all over the net in the uk and cant find one they all have double rca plugs .I dont mind ordering from the usa .MFJ dont sell these cables .
@@bruceweight7319 Bruce in this video this operator has a shop bought cable ruclips.net/video/jy8hTGmTVR8/видео.html I have ordered a stereo jack plug which will accept a rca plug in the end and i also got a male to male rca cable i hope this works .What kind of keyboard are you using is it an old AT style like mfj recommend or ps2 with an adaptor .You would think the mfj would update this unit to acept a modern usb keyboard as they still make this 464 and have done for years .
I don't have a keyboard. I use a serial cable and putty terminal program and the keyboard of my pc. She doesn't say that it is a shop bought cable, however I suspect someone on ebay may be making them and selling them. You will maybe have to look around and see if you can find one. I made all my cables to fit my needs. Can't remember for sure but I think I had to get an external speaker to plug into the 464 so that the audio would pass through, as when you plug in the cable to the speaker jack it turns off the radio speaker.
@@bruceweight7319 Hi Bruce got the the 464 to work ok with a ps2 keyboard and an adaptor and it seems to send ok but there were not many decent signals today and the few faint ones were just showing up as mixed letters on the screen , i have my 7300 set to straight key and wondered if there are any other settings that i need to alter.What about the cw pitch.
@@saltire546 make sure that the pitch level on the IC-7300 is set the same as the MFJ-464 IE both at 700hz or 500hz I use 700 hz I cant remember the menu setting on the 7300 but it ends up being used with the push button knob on the upper right of the display. There are several lists that work with that knob such as the power level. I want to say it is the code pitch on the MFJ-464 they do need to be the same although the Keyer reader is 701 hz for some reason. Also play with the notch settings as you can narrow it up a little and also try using the Noise reduction function and noise blanker. Experiment with different levels. I believe I use 6-7 on the NR
I'm not quite sure how to answer your question? The IC-7300 is a CW transceiver and of course SSB and digital transceiver as well. The MFJ-464 Keyer Reader is just that; a Keyer Reader. you can plug your Morse code key of several types into the keyer reader and it will when properly connected to the radio provide the key connection to the radio. However the radio can do the key function without the MFJ-464 keyer. The MFJ-keyer also does the function of listening to the sounds of CW coming from the speaker jack of the radio and decoding it into words. The keyer is not a perfect device to de-code the signal in all conditions. It needs a clear signal with very little static or interference on the incoming signal. The keyer needs clear and concise Morse code with proper spacing and even clarity sent to it in order to decode accurately. In reality not everyone sends code clearly. Some send in a walsy fashion and others run their words together. I will say nothing compares to the human brain for listening to a weak un-even signal in a thunder storm next to a power line and decoding it completely. I mainly use this keyer to practice sending. If you cant send accurately, it will help you get it right, sometimes you have to send a word over and over to get it to come up right, like the word "The" it will come up as "the" if you get it right, or "6" if you get it wrong. You can use putty terminal program to send with your computer keyboard and or a special keyboard made to plug directly into the keyer. Overall I like having it and use it all the time to practice and once in a while while the incoming signal I listen to and decode it and it works quite well with the IC-7300 using the noise blanker and noise filter.
@UC1sXjbSrK6WZe9YcYS4rWvA hi bruce...please help me how to set the mfj-464 on received aspects? the device cannot read cw clearly. what must be the proper setting on TONE and on VOLUME? so this device will read very will. Thank you.
When I get a minute I'll try and do another video so I can show you how to do it. I did say it wrong about the jack on one of my posts but it does need to be a stereo jack on the one that plugs into the radio. Make sure the radio is set to CW mode and you can narrow up the filter settings on the 7300 with the upper left knobs or using the three filter level settings. Also set the noise filter to about 5-7 and use the noise blanker as well. The volume on the radio had to be high enough to trigger the mfj 464. It has a level setting screw if it is set too low you will have to have the 7300 volume up way high to get it working. You can play with the two so you don't get blasted out by the volume of the radio. Mine still needs some tweaks. Summertime is not so good as lightning noise really messes things up with it's ability to decode. When I get a minute I'll try and do another video on it.
@@bruceweight7319 thank you so much in advance.I will try to do it again like what's u advice. Another one problem... Is I have a mistakes also.. I say in my other comments that I can transmit using my keyboard. But yesterday I joined the JIDX CONTEST I saw It doesn't transmit /come out my cw TX into my rdo. It's in the mfj 464 only. I'm so sad with this device. Maybe I just don't know the wiring and the set up of both units. Looking forwards for your vedio. I will wait for it. Again thank you very much.
If you look at my videos I just added a hasty made video with a little bit more on using the MFJ-464 Noticed that I had the radio set at 95 watts! Don't do CW at that level 35-40 watts is all I would do; otherwise you might smoke the radio.
How is your keyboard connected? Or what is it connected too? The MFJ has a menu item called "OUTPUT". You must set OUTPUT=ON on the IC-7300 you must push the BK-IN button to on it will show BK-IN on the left side of the display. Turn it on and off so you can see it go on and off on the display. Is the keyboard connected directly to the MFJ-464 or the computer?

What equipment do you have? I have a IC 7300 connected via key jack (#8 on ic 7300) with 1/4 mono jack connected to the ic7300 set in single key mode CW mode key function = on connected to MFJ-464 output set to echo keyboard off, radio echo on (experiment with which setting you like). 1/8" serial port on MFJ connected either to USB to serial adapter or 9-pin serial connector to computer. Computer needs a "terminal program" such as Putty terminal program that I am using. Check the manual of the MFJ-464 as there's a jumper that may need to be changed to match the keying polarity of the ic-7300 I can't remember if I had to change it. You may have to study carefully the ic-7300 and the MFJ-464 manuals to check the settings recommendations for each.
Just to emphasize for sure use a 1/4 metal mono jack to go in the ic-7300. Check how you need to connect to the MFJ-464 stereo or mono and I believe sleeve and tip.

You will need to get a soldering iron and build the cable. That is what I did; I cut the RCA off one end and put the stereo jack on in its place.
