    Hi, i would recommend a counter balance weight on the antenna motor shaft! And a slow start stop function on the motor! This will increase the lifespan of the motor and gears a lot!! 😉👍
    And it will also make it go a lot more smoother and more accurate!😁

    Thanks Alex, really interesting video. I've dabbled with satellites with a fixed white stick antenna and managed to work a few passes using an FT-847 with Doppler control via the PC. I have an antenna interface for the Yaesu AZ/EZ mount but need to spend a little more time thinking about antennae but I really like what you have set up here with the polarisation options and the harnesses.
    It has been.a slow burner project - it got rudely interrupted by a project to set up for the QO-100 geostationary satellite which has been good fun, but I can feel the LEO satellite itch returning!
    Good luck with the field day, hope you manage to post some footage :) 73 de M0SNR

    Alex, great job putting this together. I've been wanting to modify Arrow antennas much as you did for a few years. Some questions. 1) does it make any difference whether you drill the holes in front of the existing cross beams or behind? 2) I'm assuming you made a 90 degree phasing harness; any specific plan you used? 3) any unique problems you experienced reconfiguring the Arrow antennas? Thanks & 73! Jeff, WK3U

    Thanks for the video. I'm stumbling along with Arduino and satellite as well. Trying different experiments along the way. Learning a lot about the Arduino IDE? Matlab/simulink with simscape. I have a yaesu rotor head but no control box. So, am planning an h bridge with pwm and driver off a mega. Have some motors that are geared down to 5 rpm. Want to model it in simscape first...then just map the rotor controls and return position signals back into the software as actual azel. Anyway...learning a ton. Love the ladder idea...
    Have a 3 meter dish or two and thinking of eme...but that's down the road. de Tom, W5XTT...73

    Hi Alex, Great video, I am considering building a K3NG antenna positioner but instead of using traditional antenna rotators with potentiometer feedback I want to use mems magnetometer and accelerometers for position feedback which the K3NG software does support. I wonder if you have an opinion on the viability of using this type of position feedback, in particular the angular accuracy of these devices.

    • @va3ase
      @va3ase  4 หลายเดือนก่อน

      Hi I'm glad you enjoyed the video. You are correct about K3NG supporting an HMC5883L digital (magnetic) compass and ADXL345 accelerometer for feedback. I have experimented with these sensors a bit and was able to get them working on the bench, though I haven't tried mounting them to antennas for real use. It has been a minute since I looked at the datasheets but I believe they claimed 1-2° accuracy / repeatability (or less). That's more than enough when your typical antenna's radiation pattern is >20° wide. The potentiometer feedback from the G-5500 is very crude and I wouldn't trust it to be accurate or repeatable to less than 5°. It's probably worse than that actually, but still fine for most applications, only becoming an issue with very high gain and narrow beamwidth antennas.
      Keep in mind the sensors (especially the compass) will need to be mounted away from motors and power cables to avoid magnetic interference. This is the main reason I never finished testing them. It's not a big deal, just requires some planning. I hope it works out for you!

    How are you balancing the weight of your antennas? Looks like most of the weight is towards the front. I like the use of a ladder as a tripod. Do you think you will build a case for the original rotator equipment and to include all the new stuff?

  • @robcarnaroli269
    @robcarnaroli269 ปีที่แล้ว

    True about the signal report and there's very little time for that during a pass. Seems like every pass is a pileup. Does the k3ng version give feedback to the satpc32 rotor control daemon? The w9ke code I used does not and required a ton of modding to get started.

    • @va3ase
      @va3ase  ปีที่แล้ว

      Some of the passes can get pretty intense, especially on FM birds. Yes the K3NG connects to SatPC32 using the GS-232B protocol. The position feedback and output control works very well in SatPC32 or PstRotator once configured. The hardest part with the K3NG project is enabling which features you need in the code and then getting the feedback calibrated. It isn't very intuitive, but I haven't had to do any real code modifications at least.

    Excellent? Where you using a circular polarization for this contact? I was thinking about building with just a circular polarization rather than switchable or fixed horizontal/vertical with a switch as some do. Have you ended up just using one setting over the others since yours is switchable? is circular the way to go for satellite to avoid switching?

    Would you be willing to to share the 3d printer files for the control box you designed and you configuration files for the K3NG software?

    • @va3ase
      @va3ase  ปีที่แล้ว

      Sure I can post stl files for the boxes if you'd like. The K3NG code is pretty much straight from his GitHub repository with only my features enabled. The Nextion display files were downloaded from VK4GHZ's website with no modifications. The more confusing part for me is the settings and calibration which you input through the Serial Monitor after downloading to the Arduino.

  • @rogerp5816
    @rogerp5816 ปีที่แล้ว

    Very nice video. I'm going to go and watch part one now.
    I'm just starting with the K3NG rotator controller software. Would it be possible to create a video showing what you went through to configure and load the software. The Nextion part has got me a bit confused at this point.

    • @va3ase
      @va3ase  ปีที่แล้ว

      Thanks for your feedback! I wasn't sure how much detail to go into with the K3NG controller but sure I'm open to making a video focused on it. One tip is to google VK4GHZ as his website has updated Nextion files and more information on the configuration.

    @christianknight2905 6 หลายเดือนก่อน

    I'm putting together a g5500 right now and the EL moves with just finger pressure...is this normal? The az is locked solid but even mild back pressure from the cables causes it to move.

    • @va3ase
      @va3ase  6 หลายเดือนก่อน

      No, the internal gears should prevent you from moving the AZ or EL rotors by hand. Make sure the mast is not slipping, it can be hard to clamp securely without crushing it.

    Hi, Alex. I’m going through some trial and error to build out a portable satellite station. Thanks for posting these videos! I’ve definitely learned a few things, and am excited to make some changes to my station setup that should hopefully make it more viable going forward.
    Quick question for you: With the IC-9700, how crucial are the external LNAs, especially if the feed lines are kept short (10-15 ft. or less)? Do you have any operating experience using the 9700’s pre-amps rather than the external LNAs?

    • @va3ase
      @va3ase  ปีที่แล้ว +1

      Glad the videos have been helpful! I need to finish editing the final installment in the series. I do find the external LNAs make a pretty significant difference, especially with these little antennas. If you use larger antennas with higher gain (which I'll recommend) and low-loss feedlines the LNAs are less critical. Put simply, you'll make contacts without them. However the LNAs are indeed a noticeable upgrade, even with short feedlines. I'm fortunate to have these expensive ones from SSB-Electronic, but Mini-Kits offers similar LNA kits at a more reasonable price if you're comfortable soldering / building. That's probably what I'd get if I was starting from scratch. Hope that helps!

    Does the 9700 have 1 or 2 antenna inputs? Is each antenna connected to separate RF connectors?

    • @va3ase
      @va3ase  ปีที่แล้ว +1

      It has seperate ports for each band. Each antenna is fully independent with its own feedlines, preamps and polarization switches. The 9700 actually has a third antenna port for the 23cm band I'm not using presently. It's a great radio but pretty specialized.

    What size of the horizontal tub are the antennas mounted on?

    • @va3ase
      @va3ase  ปีที่แล้ว

      I'd have to measure to be sure but it's around 4-5ft long. There is probably an ideal or minimum seperation distance you can calculate, and I'm guessing mine is technically too short. For my application I was more concerned with keeping the setup compact for easier transport and setup with minimal disassembly.

      Thanks! That would be a fun idea, but the Yaesu rotator is the most expensive part which I think is a deal breaker for most people new to satellite. If I was going to sell anything I think it would be better to design lower cost rotators (probably 3d printed).
