Basics of Ham Radio Sound Card Interfaces PSK 31 and other Digital Modes
HTML-код
- Опубликовано: 13 окт 2024
- Many Ham Radio operators are interested in PSK-31. You will need some type of sound card interface to go between your radio and computer. Once you have the basic interface working, you are then ready to use many of the other digital modes. JT-65, WSPT, FreeDV, SSTV, Digital SSTV, RTTY and many more.
If this is a little too fast, watch this video too.

Randy,
I like the new format and you make it very understandable. It would help me, and maybe others, if you had a short pause at the end of each point. Keep up the great work.
nice job Randy, The white board is a good tool to use. The old saying a picture is worth a thousand words..Thanks KC6HBB
I must thank you for this video. After many hours of work and experimenting I finally got my laptop working with my FT817 because of this video - the breakthrough was setting PTT to "RTS" and I'm at last on digital modes!
73, G4KDX.
Glad to hear that you got it running. Have fun.
Thanks Randy, I've been very interested in this topic and I'm glad that you shared this info with us. It is a great overview.
As always.....Great stuff Randy. Thanks for what you do for our hobby. 73
Randy always does a good job
Mike Brooks There's always rewind.
great video - no need to slow down - easy enough to pause or replay as needed
Newish ham here. This said everything I needed to know in speedy fashion. Thank you.
Enjoy
Like the new white board format. Learned a lot,
John, KC2THY
Randy, great job on the video. Nice approach instead of just talking about it. Yea it was fast but that's why they have pause, reverse and play buttons. You're making great contributions. Thanks,
Great presentation Randy thanks! Lots of information in a concise amount of time. It excited me about getting on digital modes. I found your comment that once set up it is easy to try different modes of digital communication. Many hams are using PSK31. I am curious about JT65.
Very well produced video , , ,as usual. We'll miss you at Dayton and CTU. W5JCS
thanks
EXCELLENT video Randy. I use the EasyDigi kit. $12 and 20 minutes to solder together. Thanks for mentioning and emphasizing not overdriving/splattering. It's a big problem on the bans. W7BBQ.
Nicely done Randy.
Mike, KB1VHS
Great video! Very clear and straightforward. Love the graphics!
So much to think about. Thank you for your videos. They are very helpful.
Amazing video! All hams should know about how to send PSK31 signals. I used to watch/hear a lot distorted signals! 73 de André PY3IT
Love the whiteboard approach!
I think I ended up drawing about 4x the number of boards to get it right!
While way above my head at this time, thank you so much for this kind of info! 73s
Something new to learn
No doubt.
Lots of info, but a little too fast paced. Thanks, Randy!
I had to do it fast for Ham Nation. Here is a similar video from my past. ruclips.net/video/FmsFhz_dyAg/видео.html
Thanks Randy for another great video.
Excellent, answered lots of questions
Randy,
Slow down on the coffee a little... Watched it twice and it's a little quick for me "beginner"... but thanks to youtube and replay I'll eventually get it all. I didn't know the newer rigs had the sound card built in.
I do like the white board approach, but miss your bloopers at the end :-(
As Always, Thanks Very Much,
Mike

P.S. Prepaid for the new Icom ID-5100 that's coming out in the next week or so and am excited to move up from a HT.
new Icom, cool....
Thanks for this amazingly thorough discussion of this topic! I've learned more watching this one video than from about a hundred others I've watched put together. One question: You've presented this in the context of using the digital modes. I want to connect my Yaesu FT-450D to my computer, along with an SDRplay SPR2 for use as a panadapter. Likewise, I do plan to use digital modes. The FT-450D has both a serial CAT port and a Data port (DIN). Which connection would I use for panadapter control? Would I need a RigBlaster/SignaLink as well? I realize the one function I'd need would be to make sure there's some sort of TR switch. How does that figure into the equation? Sorry about all the questions, sheesh! I just want to make sure I'll have everything I need and not blow anything up. Thanks! ;-)
Hi Randy! Fascinating stuff you have here, I'm enjoying your videos. Since I haven't gotten a license yet and I'm still in the learning-what-I-can phase, I'm curious about using digital modes with the older transcievers that I will probably have to start out on, ie ones that don't have built-in serial or USB ports. I gather from here that as long as I have audio in/out and PTT jacks on the back I should be able to cobble something usable together, am I correct? Also, are digital modes used or allowed on 6 or 2 meter bands or are those just voice, and is this sort of thing possible with smaller mobile rigs that are being used as base stations? From what I've seen those have minimal connections other than antenna and mic, so I'm guessing not.
Hi, yes you can use the digital modes without built in USB or serial ports. You may have to connect into the mic jack and use VOX for transmit. Okay to use on 2 and 6. You may have to scare up some people to talk with. Probably not as much activity as compared to HF. If you mean smaller FM rigs, also not as much activity as SSB rigs.
Thanks for watching, Randy
If your desktop doesn't have serial ports but has available expansion slots, you can get a dual port serial card for less than $12. Amazon, Newegg to name a couple. I've used them and they work as well as built in ports.
Great video!
I've got a question that I think you might be able to help with. My club would like to transmit the ARRL Audio News over our 2 meter repeater, but I'm unsure how to hookup my Windows 10 computer to my Yaesu 2980R. I would prefer to hook it up through the mic interface on the radio as this would (I believe) facilitate the devices' use by other club members who own Yaesu 7250s. So, when I'm not available to transmit the news, someone else can... Any help you can provide to me will be greatly appreciated... Thanks!
Great job.
Interesting video but as others have said a bit faced pace. Actually seeing how the connections work might be helpful.
Very interesting and educative presentation. 73s...VU2JGI
Hi Randy, thanks for the video. I considered it to be a little too fast. I was able to understand all the basics but i am QRV in Digital for a couble of years now. I think a beginner has trouble to get all the information you scribble on your board so fast.
I understand you have to do it all in 8 min, but maybe a little bit slower ist better.

If you want to watch the video more slowly (or faster), you can use RUclips's speed control. Click on the gear icon and change the playback speed. You can change the speed in 25% increments, anywhere from half speed to double speed.
If you want finer control, the Video Speed Controller browser extension for Chrome (and other Chromium-based browsers such as Brave and Edge) lets you change it in 10% increments. (There is more than one extension with that name; I use the one from igrigorik.) The extension will also let you change playback speed on other sites such as Vimeo and Netflix. You can get it from the Chrome web store. Similar extensions are available for Firefox.
Even if you have a radio that does not have a built-in sound card, if you have CAT control working (either over a real serial port or via a USB to serial converter) you can use CAT for PTT rather than a physical line on the serial port. Only some radios support the CAT commands for turning the transmitter on and off, so check your radio's manual and test your setup to make sure it works.
Are all Ham digital modes based on tones? Wifi and LTE I think are radio data connections not based on tone? Looking for video Ham data connections using tones compared to Wifi for beginners
Many of the ham digital modes use the standard audio input and outputs on a pc. So, the modes use tones or phase shifting of tones.
The problem I noticed is many of the sound card interfaces add delay, due to their latency. They often use slow mechanical relays or some built in USB audio soundcard codec that makes either the PTT or audio sluggish. Why use mechanical coil relays today is beyond me. For about $2.00 you can get reed or low power solid state relays that switch about 100 times faster and since they're not mechanical, they don't wear out like the older mechanical relays used to.
Pretty much any laptop computer has audio out and microphone in. This implies that there is some sort of sound card functionality built into the laptop. So why don't programs like DigiPan recognize it and use it? Why do we have to spend $100 to get an external sound card?
+David Jensen You can use an internal sound card. You may have to make a simple interface.
Amateur Radio International : facebook.com/groups/TARGNF has several excellent articles in the unit Digital Ham Shack : Hardware / Software on selecting the right sound card for digital modes including how to evaluate individual sound cards based on Bit rate, Bandwidth & Dynamic Range. Which ones to buy & which ones to avoid.

Yes, do like the new form. But for me, way to technical and you move very fast. Granted I can pause and rewind, but that gets old.
Give this a watch ruclips.net/video/FmsFhz_dyAg/видео.html
Hi Randy i ordered a easy digi interface from eBay for my ICOM IC-7000
