  *HOW TO CALCULATE FOR BUILDING A RECEIVING MAG LOOP*---I need a calculator or formula that can show the measurements for building a mag loop for receiving a frequency range. Is there any formula or a calculator for that?

  I'm not familiar with the motor option of that antenna. I tried to check for some information online but I saw a few variations of that motor. The controller is designed to control a stepper motor. I think that they are providing a DC gear motor.

  Excellent job. Amazing workmanship. I read somewhere if you give the small loop a more oval shape (side to side, not top to bottom) it will increase the induction area between the two coils. But if it's not broke, don't fix it!😅

• 
  @reHamRadioАй бұрын

  Tests shows that the SWR is going down when the two loops, large and small, have more area in parallel. Not going to break it now :)

  Thank you so much for this! I am working on this project now and have got all my parts to put this together. I am going to 3d print all of my parts to hold my boards and motor in place. I am using an air variable capacitor that doesn't have 360° of rotation. Could you tell me how to go about adding 2 stops in the code so I don't stop the stepper motor at the end of the capacitor rotation and continue powering? I am afraid I would damage my stepper motor pretty quick.

• 
  @reHamRadio2 ай бұрын

  The latest software version already contains "Memories" which can be used to set specific locations to stop the motor. In addition, the software provides the option to set virtual limits, that will act as the min and max range for your capacitor. Please check my website as I explained how all the features can be used. Good luck.

  @charlesguerin49012 ай бұрын

  I can see you hit 40M-20M, what change would be needed to get good SWR at 10M?

• 
  @reHamRadio2 ай бұрын

  It's a combination of the size of the loop and the capacitor range. I would recommend checking the options using an online mag loop calculator, and set the target frequency to 10M and see what are the needed parameters of the loop and capacitor. Good luck.

  Great presentation. However, I confess to being surprised by a bad connection between the rotor shaft and electrical connection of one good looking but old variable capacitor - only about 0.25 ohm by my milliohm meter but with a radiation resistance in the 0.3 ohm range you could, potentially, lose half your power in the capacitor shaft connection and never know it! Does anyone else have a comparable finding or am I the unlucky one? Neil, AB4YK

• 
  @reHamRadio2 ай бұрын

  @Neil, do you have any isolation between the capacitor and the motor? I didn't understand if you are using any. Please review the KZread videos, all of them show a wood rod in between.

  No, the capacitor range should fit the frequency range that you plan to use. The best will be to use an online free magloop calculator and check the options.

  At 45:00, regarding circular polarized antennas. Consider that moon is a reflector and thus it change RHCP to LHCP and vice versa. Then, you should to use two antennas, one LHCP and one RHCP, depending what other person in QSO have... or give up - just using cross-polarization.

  At 41:05 you said that we should to make QSOs "early morning, late evening". What about those cubesat small satellites that works only on solar power? They does not work during night passes.

• 
  @reHamRadio6 ай бұрын

  Thanks for your question. The answer is yes, we can use the cubesat during the night as well as the satellite is charging it's battery using the solar panel on the other side of the earth, where the sun exists. The battery can hold the cubesat for a long time, so you have the option to use it day and night. I hope it answers your question.

  @@reHamRadioOkay. Thanks. Currently trying to listen few linear satellites over Europe. So far no trace of any signal. My antenna is 1/4 lambda GP on the roof. ISS repeater at 437.800 MHz is strong, NOAA 15, 17 and 19 are strong (137.xxx MHz). Just not sure those small cubesat with maybe 0.25W of power, how strong or weak might be.

  I have the 155 ft OCF non resonant antenna with 100 ft of coax. My entry into the shack is only about 50 ft from the ground about 35 ft below the antenna mount. Knowing I shouldn't coil the feedline coax up should I run it away from the shack and then back to the entry (that would be the opposite direction of the antenna wire) or should I lay it out on a run past the entry point and then back to it? Also can it be suspended or should it lay on the ground?
