Sample PSK-31 QSO, AD# 27

[@branvinivideo]

love the honesty as you learn during the demo, still a great presentation, appreciate all you're hard work!

[@Peter-tf2uc]

Thank you Dave for a really great explanation and demo. I only wish there was less of a 'Rewinding demo tape' clip :)

[@adelarsen9776]

Dave, you are an Officer, Scholar and Gentleman. A real doyen of HF radio and the mystery of amateur radio. Well done - although I have no knowledge of PSK31. I'm still grasping with FEC, SSB, CW and AM.... Thanks Dave - you're the man. Cheers :-)

[@davecasler]

+Ade Larsen Thank you!

[@warplanner8852]

You two get a room, will ya?

[@wbhinton]

You helped me earn my Amateur Extra! Here's a cold one on me!

[@KX4UL]

Excellent video Dave! This was very helpful as I have been absent from Ham Radio for almost 10 years and just starting back as of February 2018. I am just now getting into the digital modes, other than Packet that I ran back in the early 90's. Living in an HOA antenna restricted home makes it tough to operate with much power using my concealed antennas. The digital modes will give me more options for making contacts at a low power. This video answered many questions for me as did the previous #26 video. Thanks so very much for all you do to advance Ham Radio. 73!

[@RobMacKendrick]

Thanks for this, Dave. I'm trying to learn PSK and fldigi, and it's proving difficult for an old brasspounder. Seeing someone else do it is helpful.

[@BretChilcott]

Dave, think you for sharing your knowledge. Your videos are greatly helping the HAM community expand and grow. 73. Bret, AC0AE

[@wbhinton]

You caught me in a QSO with WD1U! 14:36 WB5WBW. Pretty cool to see what my signal looks like on the other end!

[@TheRealKnightOfNight]

Another fantastic video. I really enjoy videos showing actual QSOs and I'm really looking forward to digital modes.

[@timpastor3054]

Videos are extremely well done and very helpful! Thanks for all the info and effort.. 73. Tim. N8HUS.

[@tankerbanker2001]

Well done Sir! I’m getting back into the hobby and your videos are a tremendous help! 73s. B

[@TheRightPlanet]

Hello. David. I have watched your Tech and General Class tutorials, while reading the ARRL manuals, per your instruction ... and studying at hamexam.org and hamstudy.org, I just received my CSCE for General Class ham operator today. I'm very excited. I just wanted to thank you. I know making videos like yours requires a lot of effort and time. But, because of hams like you, I passed my Tech and my General today. I have a lot to learn. But I look forward to learning it. The VEs said my prefix callsign should be KD9 (Indiana), or something. Thanks again, David. What a fascinating hobby ... and really good people. 73.

[@davecasler]

+Brent Parrish Congratulations and welcome to ham radio! I'm glad you found my videos so helpful. 73, Dave

[@Drekkag]

Great video again Dave. Also would like to say I use Airlink Express myself. It does PSK31, PSK63, MFSK, and RTTY. Another great free software that is simple and easy to use. Just thought I would add to the list for those looking into digi modes. 73s, Adam Rennison ad0am

[@davecasler]

+Adam Rennison Thanks for the info

[@michaelcox436]

Exactly what I wanted to know. Thank you. But I'm curious why you keep the maddening audio on, lol.

[@RCVinyl]

Dave, Very well done. Just found your channel from watching you on the latest w5kub round table. I picked up a Rigblaster Plug & Play at the Orlando Hamcation last weekend. Your video will help me greatly. Thanks and 73.

[@GaryWaldronUK]

Obviously just me but I did not have a clue what was going on in this particular video. What was all the rewinding about? Did I miss something? You completely lost me Dave, sorry.

[@edwardkerns5202]

See you on digital Dave. Very nice segment as usual. N1EK

[@BentConrod]

It is unfortunate, especially for a demonstration, that for the entire QSO both and were populated with David's call.

[@fudgesauce]

David, thanks for the video. That helps a lot. I decoded my first "in the wild" PSK-31 stream earlier today. I don't have a license, but I'm kicking the tires by using a websdr site and then using fldigi to see what I can snoop off the air. One thing that I haven't seen explained anywhere, probably because the convention is so well known among ham operators they don't think to mention it, but is there a standard convention of using only USB or LSB for digital modes? For CW it doesn't matter, but I believe for most digital modes if you use the wrong modulation the spectrum will be mirrored and garbage will be decoded. For voice band comms it is easy to distinguish USB from LSB, but not so for digital modes. So far I've had a few successes, but many signals I'm unable to figure out and I'm sure I'm wasting a lot of time flipping between USB and LSB to see if that is the cause of my problems. A number of times I've seen what looks like an obvious RTTY signal but have been unable to decode it -- maybe it isn't rtty after all, or maybe I haven't found the right combination of usb/lsb x baud rate x character set. I'm beginning to suspect that it is RTTY but it is communicating something other than text, as these streams have no breaks and just go and go and go. Thanks again

[@RadioHamGuy]

Thanks Dave, this was a big help and looking to try this mode, I like having a conversation rather than some of the modes. One thing I didn't pick up on yet, I was wondering...sometimes I hear it as psk-31 and other times bpsk-31, I take it they are the same mode? Somehow I missed this when people talk about this mode. Thanks and keep up the great work. 73..wd0akx

[@davecasler]

PSK-31 is actually a family of modes. The most common is Binary PSK-31 or BPSK-31.

[@edvac1]

Great video, Dave. Thank you!! I'll be trying this with a Raspberry pi 4, and my main computer with fldigi. 73 WA7AXT

[@jwerp0]

Dave I enjoy your videos very much. I also have used your series on the amateur extra class exam to have passed my extra class test a little over a week ago. I did notice on this video that when you clicked on the QTH of N7NES and replaced his name with his QTH you also overwrote his call with yours. Then starting at 9:47 when you start using your macro (3rd from left) to send the call signs you end up sending KE0OG de KE0OG instead of N7TES de KE0OG. Best Regards Jim - WA8MDC.

[@davecasler]

Congratulations!

[@JoeLalumia]

Dave-- very nice video on PSK31. All the best. Joe W1XWX

[@MichaelLloyd]

Very nice Dave. I've been wanting to try the digital modes again and this will kick me off, after I put up a Gap Titan DX that hasn't been ordered yet 73 NE5U Mike

[@somebbody]

Thank you Dave and also thanks for helping me pass my General after 27 years Hi Hi 73 N3xei

[@davecasler]

Congratulations on your upgrade!

[@kevinj8258]

Your signals are so strong and clean on 20M. Thinking I have a noise issue as the S meter never goes below S8. Looking at your waterfall everything looks so terrific and clear, to at least start the decode process. Have only had success on JT65 when the bands are "open". What antenna system are you using?

[@davecasler]

+Kevin J Local noise issues can be frustrating! Try various grounding techniques or rearranging cables to see if that helps. There are lots of ideas for reducing radio frequency interference at www.arrl.org/radio-frequency-interference-rfi. Regarding my antenna, it's a ground-mounted Butternut HF-9V multi-band vertical. I completely refurbished it a couple years ago and have been quite pleased with its performance. 73, Dave

[@stevefowlkes6031]

Hi David, Thanks so much for your videos! This one is great.. I have two questions though. When doing psk31, (or any of the digmodes) The frequency on your transmitter *must* match the same frequency that is on the top left (in this case 14.070 Mhz) correct? Also can you transmit through psk31, but talking directly into the mic on your computer and have it sent to your plugged in transceiver? or does psk31 only exclusively work with keyboard input?

[@davecasler]

Not necessarily, although that is best practice. The software in your computer locks onto the signal. The two signals are on the same frequency, but let's say your radio reads 14.070 MHz, and your signal is 2 kHz up from that, and the other guy's radio reads 14.071 MHz, and his signal is 1 kHz up from that, you both end up conversing on the same frequency. Hope that helps. 73

[@gabes80]

Good video. All “noted!”

[@profdc9501]

This video would be a lot better without the periodic inserted tape warble. It makes this video really hard to watch.

[@tomjudge7168]

Dave can i hook up a kenwood TS530S for digital ham radio ?

[@tglenn3121]

Hi, Dave, I don't suppose you know how / where I can get the 'file' I need for fldigi to recognize the Icom 7300?? I've been searching all over the internet, but cannot find it. I should mention that I'm trying to use my Icom 7300 with fldigi on a Mac. Apparently, the file needed to use it with Windows is readily available, but the file for Mac is not so available.

[@davecasler]

Take a look at www.w1hkj.com/files/flrig/ and see if one of the flrig files is for the mac.

[@warplanner8852]

It's a good video but, boy Howdy, is that rewind annoying!

[@dougrea]

yet another great contribution to the hobby! What did you mean by "nudging" the ^ ?

[@davecasler]

Do you recall where in the video I used the term?

[@dougrea]

Sample PSK-31 QSO, AD# 27 I have since figured it out and am enjoying the mode. 73 and thanks for all you contribute to the hobby

[@swashington942]

Thanks Dave.

[@kevinj8258]

Just wondering why you do not have an AUDIO ONLY version online for PODCASTS subscription. Would be nice for people driving to listen while driving.

[@davecasler]

The videos depend heavily on the visual content, so I've not released the audio separately.

[@daleythmpsn]

Can this be used with a baofeng handheld that’s all I have for a radio

[@neilmarsh1904]

You had Puyallup right the first time. ;)

[@MeineVideokasetten]

Hey dr op Dave. Nice video!!! Here's a error in the macro, I guess: 10:34 'btu John KE0OG de KE0OG k'. EDIT: I just saw: Not in the macro, in the name. Okay.

[@joemirsky8815]

Dave, do you have a preference as to coax, i.e., LMR 400 or RG 213?73 / Joe M. KA5LJB

[@vw68autobug]

I use RG213 for HF bands and Belden 9913 for low loss on VHF & UHF bands... VK2LEE Lee

[@davecasler]

My favorite coax to work with is RG-8X, which is great at HF. I prefer RG-213 to LMR-400 because it's easier to work with. I still have half a spool left of LMR-400, though, so I'll be using that for awhile. LMR-400 is an absolute pain to put connectors on.

[@CroakerOutdoors]

Hi David, just discovered your channel and you have done an exceptional job explaining PSK-31. Looking forward to earning my general and extra tickets to begin using HF and digital! +1 sub from me, 73

[@davecasler]

Thank you!

[@eddy2561]

Found memories running PSK31, but old news now..... / k6sdw

[@TheRealKnightOfNight]

Does fldigi do any logging of the QSO?

[@davecasler]

It has a rudimentary internal logging program. Recently the N3FJP All Contact Log program has been made compatible with fldigi. 73, Dave

[@fasnuf]

So glad Dave quit using the tape rewind sound effect. uggh!

[@thatcrazywolf]

Is it possible to work a frequency split so two people can transmit and receive at the same time?

[@davecasler]

Multiple people can use PSK-31 in the same frequency band because each transmits a very narrow signal.

[@johanvanzijl8837]

How do you connect the ft 857 to the computer ?

[@davecasler]

Check out the owner’s manual.

[@jeffreysmith6910]

The rewind effect is super jarring. Just pause the video or something.

[@davecasler]

Yeah, I didn't like it either.
