    Rob, I have thousands of FT8 contacts in the log. I really enjoyed your video and both learned a few things - and confirmed my 'techniques'! Your WSPR suggestion at the end never occurred to me! Thanks for that suggestion! I'm subscribed and looking forward to more of your videos. 73, Howard, WZ4K

      Hi Howard! Thanks for the feedback and taking the time to watch the video. Yes, with WSPR, I fear that in the stampede to FT8 that WSPR may have been forgotten. I'm currently using it to test both tx and rx on two new antennas. Really handy. Cheers mate. Rob VK3BVW

      WSPR is very valuable in probing propagation before being able to switch to FT8 or even voice for a contact

    I've been using the JT/FT modes for almost seven years. It was fun to see how contacts could be made with very low power and then even reducing it further. With the arrival of FT8 things deteriorated somewhat, as power levels were obviously increased by many to compensate for the reduced low signal capabilities.
    You best tool is the RF gain, learn to use it and thus avoid the involvement of AGC.

    • @RobVK3BVW
      @RobVK3BVW  ปีที่แล้ว +1

      Agreed! The RF gain makes a huge difference to success in hearing FT8 signals. Thanks for your observations.

      Thanks for your comments, Eddy. I picked up two new countries this week, so I'm not quite bored with it yet! 😉😁 Mixing FT8 with other aspects of this vast hobby has helped me maintain my interest, especially with the higher freqs opening up. Had some nice FT8 contacts into Japan and Sth Korea several weeks back on 6m - not bad from here at the bottom of SE Australia! And no 6m beam either! Sadly, my CW skills are abysmal, so I steer clear of that. Cheers, mate! Rob VK3BVW

    Thanks Rob, very much enjoyed your inspirational video. I have just returned to the hobby after 30 years and am fascinated to learn about new developments and modes etc. I spliced some cables last week and was amazed how much I picked up on FT8 using only my vertical hf multi band antenna. I'm waiting for cat control cables to arrive. Can't wait to get started. Hopefully work you down the log! 73 Rob G1VXD.

      Rob, thanks for your generous comments and feedback. Much appreciated. Good luck in getting started with FT8. Being so close to Europe and North America, you should be able to make plenty of QSOs on your multiband vertical. 73, the other Rob! VK3BVW

  • @johnwest7993
    @johnwest7993 2 ปีที่แล้ว +1

    I'll be using a high Q magnetic loop for digital modes. Spending a little time tuning is the price paid for keeping the bandwidth narrow. But the narrow bandwidth antenna solves a lot of problems before they ever start, from noise to overloaded front ends.

    Great video, Rob! Although FT8 might be a polarizing mode for some hams, there's no arguing that it's certainly brought a lot of ops out of the woodwork! I think it's downright brilliant and I've enjoyed working DX with a seemingly propagation independent mode!

    • @RobVK3BVW
      @RobVK3BVW  5 ปีที่แล้ว +1

      Thanks, Thomas. I liked your comment on the "seemingly propagation independent mode". Indeed, it can be somewhat deceptive and "seemingly". However, the laws of physics and such still apply! A few nights ago, I heard another VK calling "CQ Europe" on 80m using FT8. The time in Europe was around midday!! Needless to say, he never got a reply. He is the definition of a true optimist!

    FT8 is old news, get on JS8 Call , it’s a great mode, I use it a lot, can have your station automated and can make QSO if I want to, it’s convenient when I don’t want to go to a cold shack or leave the xyl, I can make contacts while she watches tv.

And I enjoy quick QSOs with no fuss or waffle talk. :-) I might take another look at JS8CALL again and see if it has grown in popularity since I last looked. 73, Rob VK3BVW

    Thanks for this video Rob!
    I'm running a Yaesu FT-991a and was trying to use all the 'online' advice about keeping the ALC as low as possible and couldn't seem to get much power output. After talking with Yaesu technical support they mentioned as you did that on their radios you do need some ALC present on the meter. I'm going to try some of the other tips you mentioned as well...Thanks again for the great vid!

      Hi Corey. Thanks for your feedback and comments. Much appreciated. FT8 is such a great mode for those of us without "super stations" running multi-band beams on towers at 100 feet, etc. Although the video is more than four years old now, I think I'm pretty happy with the advice there. Although I don't seem to need the notch filter tip - I suspect that may be of more help to those with many other hams living in close proximity. Down here in the lower southeastern part of Australia, there are not many local hams and the population is more spread out. If you hear/see me on the air, please give me a call! All the best, Corey. - Rob VK3BVW

    Good tips! HOLD TX FREQ should be a default and used by more hams. 5w from Alaska on Ft8 would be useless on 40m. I run up to 400w with a 5el beam on 10m-30m and still have problems. Congrats on using low power and making contacts though. Location is a big factor (rough in the arctic under the aurora). 73

    Hello Rob. I am new to FT8 so this video is great for me. I find that I get one QSO for every 10 CQs I click om , not a very good average. I have been over and over my setting and all looks good.
    Is this the normal ratio 10-1 for FT8 QSOs. BTW which computer logbook are you using? You had it up when you showed your 5 watt QSOs. Very impressive.

    • @RobVK3BVW
      @RobVK3BVW  5 ปีที่แล้ว +2

      Hi Chris. Thanks for taking the time to check out the video. Let's get the easy question out of the way first! The logbook is MacLoggerDX, and obviously for Apple computers. It works very well, has heaps of features and the support from the software author is first class. It's more expensive than other Mac logging software out there, but worth it.
      Now, to the 1 in 10 QSO strike rate: Your success on FT8 or any other mode will depend on your station setup. Antennas are important and power does help. I have only wire antennas at low heights and I run between 5 and 40 w most of the time. I also have a big hill running to the northwest and west of me that makes transmitting to that part of the world damn near impossible. So my strike rate is probably similar to yours. In addition, Australia is well away from the action than you northern hemisphere guys have. I can imagine that the bands are VERY busy in your part of the world with European and Nth American activity. So perhaps you have greater interference problems that would make it difficult to get a signal through? Good luck, Chris, and thanks for stopping by. 73, Rob VK3BVW

Went to HRD to see if using this program, found out that I need a cable from cat RS-232 rig control. Need to get SCU-17. And not use the signalink. Guess saying I don't have the correct cable from radio to laptop.
    First my name is Paul and my call is KQ4CD and been off the radio 23 years. With all this technology I get lost. So I don't understand all of this, but trying. I believe that I can get it done just don't try to do it all in one day. Being told just TH-cam it. It just not good at doing anything to technical. Under settings can't find the correct radio and some of the programs don't have my radio.

    The trick to the ALC setting is to find out where 0dB ALC is on your ALC display. I believe the DX3000 is one where 0dB is halfway up the scale where on most all other rigs any ALC indication is > 0dB.
    Here's a document which 'splains how to set your tx/rx audio and understand your rig's ALC.

    • @RobVK3BVW
      @RobVK3BVW  4 ปีที่แล้ว +2

      Jonathan - Since making the video back in March, I have continued to experiment trying to reproduce what some others have been able to do with registering no ALC at all in their FT8 transmissions. I have now been able to do this with the following settings:
      On the Mac - the Audio Devices window - USB Audio CODEC at 0dB (or close to that!)
      On the FTDX3000 - Menu 076 - Mic gain is between 7 and 9. The power output is set to 100w.
      In the FT8 window - Control the Pwr slider (RH-side) to set the desired power out.
      The above settings mean that the ALC meter will NOT be activated. However, I find that the ALC meter readings change as the rig warms up (say after 5 min). Don't ask me why....I have no idea, but several people in one of the FTDX3K forums have mentioned this exact same ALC characteristic as well. It can also change from band to band.
      Having said all of the above, I have monitored my signal both with and without ALC action, and there appears to be no difference in quality of modulation....as far as I can tell. As I said in the video, at least for my rig, some ALC does not appear to incur any distortion in my signal. On one occasion, just for an experiment, I pushed the ALC to flat-out, but still I could not detect any distorted modulation in my signal. So, I suspect the above settings will vary from rig, brand to brand, etc.
      Actually, I should update the previous video for 3K/Mac users like ourselves, as someone else may find my settings of help. Thanks for checking out the video, Jonathan. Vy 73, Rob VK3BVW

      I turn out the audio drive until the ALC does not react at all (ICOM 7300). On the other hand, my ICOM 735 does not have a "sharp" threshold of ALC and any signal at all produces at least a small ALC deviation. There's actually a calibration on screen in that case that signifies *overdrive* and that's what to avoid; up to that point really it is just a power meter.
      If the ALC reacts, it changes the shape of the RF envelope and that's ungood. Not bad, just not helpful and driving it to the ALC kicks in doesn't go much for you. What is important to FT8 and any digital mode is CLEAN signal. You don't need power, it needs spectral purity.

    Hi Rob great video thanks a lot for the tips you gave. I just started with FT8 but have some problems with the receive audio. The receive audio is far to loud the barmeter reach about 80 and turns red. I'm using a Kenwood TS-590s and a usb cable to run FT8. I've turned down the input on de TS-590s to the lowest point 1 but its still to loud. Do you have any suggestions? Thanks in advance and keep up the great video's. 73 Dirk PA1BD

      Hi Dirk. Check your computer sound card. The input volume on the card needs to be less than half scale. You don't need much audio going in to get excellent results. Too much audio produces problems and overload in the sound card and the software. That should fix the problem. 73 Rob VK3BVW

If Joe Taylor re-released psk31 in his own name and called it JT-31, or Oliva as JoeTaylor 500-16, all everybody would go there and be amazing at the new weak signal technology and we would all be communicating again.

      Although internet is convenient for facilitating accurate time synchronisation, which is necessary. Alternatively, GPS can be used to keep a real time clock honest or in the absence of an RTC, such as with the Raspberry Pi.
