- Making sure this is set correctly will ensure you get the most out of FT8!
In this video I will show exactly what the frequency in the black box means and how to set your TX/RX frequencies on the waterfall for optimal operation in WSJT-X and especially on the FT8 mode.

Thank you for explaining the bandwidth frequencies -- tx and rx -- and how that correlates to the dial frequency. Now it makes sense but didn't just looking at the gui.
Glad to help!
WOW, great explanation! I was not understanding this bit at all and now it makes sense, well done.
Glad it was helpful! Thanks
So, I just spent all day going down a rabbit-hole and found this video on the other end... Someone said that I was transmitting off frequency on 10m. And I am too new to know any better... But that few seconds where you explained that the spectrum of FT8 use goes from xx.074.000 to xx.077.000.... Explained what I was trying to figure out.
Despite all of the hassle, I did learn how to calibrate the frequency of my IC-7300 both within it's menus and a much more precise method of using WSJT-X to calibrate the rig!
Thanks for what you do. Your videos are a huge help to us all.

Thank you Spencer!
I'm glad that it helped in some way.

Hi Hayden,
Very good description and visuals. Stay safe. 73 WJ3U
Would have to look it up, but there is an allowance for overlap in signals too, so you don't have to worry about stepping on too many toes unless you're trying to TX straight over the top of someone.
This is immensely helpful đ„đđ„°
Glad it was helpful! Thanks
I've had over 75 decodes in one cycle, so quite a few over-lapping when things get that busy. I don't worry about having to absolutely find empty space to transmit because FT8 decodes signals on the same frequency just fine.
This is so helpful. I needed this video!
I doubt this warrants a video tutorial, but why doesnât my DT (time offset) display?
Outstanding 'splainin!

FT8 is keeping ham radio alive!
That it is good sir!
Ditto
Tnx
Awesome! This is obvious to some. But not everyone. You should really think about breaking this down in other places if you like.
tnx Hayden
No worries thank you!
Would you want both the green and red right on top of another? Or would you move red to an open area separate from green?
Love ur videos help me set up my wsjt-x ft8 station. IC7300. Just turn 87 years old, ham since 50's. everything works great, IC7300, wsjt-x, log4om, qrz, lotw etc., except (lol) my wsjt-x screen when i transmit doesn't show my time o.1 etc, everyone's shows up not mine. use all kinds program setting up correct time, don''t think thats the problem. keep up great videos. wa7sfe ex wa9wpk
I'm not ready for FT8 but what I do know is that waterfalls are the best invention for HAM radio. :)
Just donât go chasing them! According to TLC anywayâŠ. đ
@@HamRadioDX haha, took me a few seconds but I got it!đđ
It may also be helpful to know that the red marker is TX freq and the green marker is RX freq. Depending on settings in FT8, these markers (freq) may be different.
Yes! Thanks Daryl
So many people still TX on the DX stations frequency. Time to set 'Hold TX Freq'.
What is your call? Worked several vk7.
thanks for all the help buddy. ..Ray
I'd like to know how to put my location in, like some people have in the description they're located in say Canada or Peru. Also how do you CQ to a specific country or state? Thanks for all you do for the service.
@Ham Radio DX , I would really like to know how this is done as well!
Well done son!
Thanks Ape
đââđââđ€·ââ Im new to ham radio & still learning FT8, I have the FTdx10 radio of only a few weeks now & when i click on to change frequency in ws-jtx it sets my radio "DATA-U" but you said it should be "USB" đ€·ââ is my radio set wrong with it being on DATA-U as it auto picks this itself.. I do get contacts but from the UK I'm just about reaching france, Germany, and around that location. I thought with FT8 you could get much further than on the airways đ€·ââ I'm getting nowhere near what I can reach on the airways.. maybe I'm setting this wrong??
can anyone please advise me.. many thanks..
I'm new to ft8 and wsjt-x. If I'm going to use ft-8 only what version of wsjt-x should i download the updated or one of the older upgrades. tx
Hey mate, yes that's the best thing to do. The latest stable release is 2.5.4 - physics.princeton.edu/pulsar/k1jt/wsjtx.html
How do I switch from FT8 to HF voice mode
How many times should I let it transmit CQ? Will it stop eventually?
Yes - that is dependent on the "TX watchdog timer" amount in the menu settings
@@HamRadioDX Thanks bud. 73 from KQ4GDB
I'm a little confused as to the relationship between the actual transmit frequency and the audio tx frequency. I'm running an ft-857d. If I set an audio frequency above 1500hz, WSJT-X moves my dial frequency down while transmitting, above that it moves it up. Is that expected or am i missing something?
Do you have split operation turned on?
k0pir.us/wsjt-x-split-operation/
Yes I do, so I fully expect to be transmitting on a different frequency from receive for sure, just trying to understand the relationship between the transmit audio offset and the actual transmit frequency.
@@HamRadioDX I think I've figured out what's going on. I'm not sure what the ACTUAL transmitted audio is, but it seems that WSJT-X simply moves the transmit center frequency up or down to make the transmitted audio be very close to the center of the upper side band on transmit, hence it moves up for audio selections above 1500 hz and down for those below 1500hz. It makes sense but unfortunately I can't find where that's described in the WSJT-X documentation.
@@redtide08 hey mate, this is documented under the "Radio" part in the user guide - although it probably isn't well described.
wsjt.sourceforge.io/wsjtx-doc/wsjtx-main-2.6.1.html#RADIO
Split Operation: Significant advantages result from using Split mode (separate VFOs for Rx and Tx) if your radio supports it. If it does not, WSJT-X can emulate such behavior. Either method will result in a cleaner transmitted signal, by keeping the Tx audio always in the range 1500 to 2000 Hz so that audio harmonics cannot pass through the Tx sideband filter. Select Rig to use the radioâs Split mode, or Fake It to have WSJT-X adjust the VFO frequency as needed, when T/R switching occurs. Choose None if you do not wish to use split operation.
@@HamRadioDX ah, great thanks for that. That does match my observations of what it was doing in transmit, moving up and down the band to keep the output within the approximate center of the USB passband. The missing piece for me was that there was that 500hz wide window that it was shooting for.
Should I use straight USB or DATA USB?
If your transciever has USB data mode, probably best to use that for FT8 (or any data mode). This should ensure that any speech compression, processing, EQ, etc. that might be enabled for speech in USB mode is NOT enabled. Generally, you don't want to have any of these features enabled when using digital modes. On TX, especially it can result in distortion and interference.
@@Steve-GM0HUU 991A
Hi Cape Cod, yes as Steve said USB data mode if your radio supports it which the FT991A does. Cheers đ
Recommended menu settings for the 991a are:-
062 Others
064 +1500 Hz
065 +1500 Hz
ALSO set the received bandwidth in USB data mode to 3000 Hz which is the widest setting. You will likely need to set this on each band.
Hayden, how did Diana Adams do in todayâs Tas election?
Uh⊠I dunno, she wasnât in my electorate lol
you could be the same frequency it dos not matter .
ie 1000 1000 2 diffrante amateur stations ft8 will still work ok.
Why ft8
Ultimate click bait title (Not in a bad way) - I just have to know.
Thanks for watching Liberty.
Bla Bla nothing else
Great video,between this one and the one you did with t,o iam now working ft8 n iam the worst person ever with a computerđ€Łđ€Łcheers guys đđ
