  Nice setup. I too have a TS590SG with my SDR hooked to the receiver port and I like it. I don’t really have a 2m/70cm base rig yet. I just use my handheld for now. I found your channel looking up solar and Ham and you were one of the only channels I found regarding RFI. So I have enjoyed watching some old videos of yours. Thanks ! 73 de KI5HXM

  New subscriber here. Fellow ham. I have seen reported problems from Solar Edge and maybe a few others. Maybe the other was enphase. The ham that posted the video said the DC optimizers were as RFI probes as the micro inverters. I am new to the ham hobby and am considering solar. Do you recommend any equipment to scan for RFI? My SDR is bolted to the desk in my ham shack so I was thinking of portable walking around the property and such. Thanks again for the video. All the best from north Texas. 73 de KI5HXM

  you do not need a portable sdr. If you have RFI you will know it on you stationary one. I had an SDR on my bench in the shack and it was obvious. I do not have microinverters . I have and older Solar Inverter in the basement.

  This is what I have found, being off the grid made us think outside the square. MPPT chargers are efficient yet noisy, so are inverters, I tried different makes and brands yet ALL emitted RFI to a certain level, none were radio friendly. If you think noise is not coming out of your DC solar panels, think again, I ended up using cheap main to 12v transformers as the filters for the DC line, those were used in the secondary stage only (making sure the current could be handled by those transformers) this move alone took 60% of the noise down, what a win. Now the inverter itself, yes, it is noisy as well yet installing high current EMI filter as close to the inverter output as possible solved this problem as. NOW we have the inverter/charger working and the noise level drop to a pre solar install times. I have tried twisting cables and clip on ferrites many times before, yet the outcome was never satisfactory till the above was done. Now back to playing radio.

  @@PracticalEngineeringSolutions ??? every installation is different, look at the DC line coming down from the solar panels to the MPPT charger (those could be 100-500V maximum rated open circuit voltage, the system should have been designed according to what your MPPT can handle. Some insulations have 2 lots of separate solar panel arrays with two separated inputs for each array, All my DC lines are going through a cheap main transformer ( I found the 220v to 12v 20A to be a cheap option about 17USD each) I use 2 transformers for both the plus and the Minus side and placed them BOTH as close as I could to the MPPT/Inverter inputs, this alone dumps all low FRQ A.C noise originating in the MPPT Charger and stops it from going up to the solar array using the DC lines, the last thing you want is for your solar array acting as an antenna , no AC noise =no noise there, please note!! the DC goes through the secondary side of the transformer, the primary is left open and unused. As for the inverter output (solar created mains AC power using the solar/battery source) you will have 2 wires there (AC mains) those have to go through EMI filter, you will have to get the maximum current you will be using ( my one was rated 250v /40A), this will help you get the correct filter for the job and,,,,,,,,, walla DONE! , no more RFI>

Also, if you knotice in your video, a lot of the water is overshooting and on the structure of the raised bed. So the shade cloth serves a secondary purpose of redirecting that water back into the bed. A third function of the shade cloth is to reduce the amount of evaporation. I like stacking functions. 😁

  Hi Jack. Just watched your video on promoting your books. Very interesting information. Thank you for sharing. I assume that Amazon is printing the railroad lighting books as they are ordered and shipping them out? Do you feel like they are compensating you fairly since you provided all the content?

• 
  @PracticalEngineeringSolutions3 ай бұрын

  Yes, they are printing them as ordered I believe. The royatly I get (like everyone else) is 60% of the profit after printing costs, order management and shipping costs. For me, it is just under $3.00/ book. If it were an eBook I would get 70%. So Amazon gets between 30%-40% of the profit, That seems to be a little high in spite of the fact they do recommend the book in some cases and have a very large customer base. In addition, I use the other platforms to drive the readers to the book.

  It's indeed a very easy solution but there are more elegant ways to do it nowadays. LED's are current driven devices and it's quite easy to use ICs to build constant current circuits that can have the current value adjusted to control brightness and work almost independently of the supply voltage.

  Cotton seems to work as a nice diffuser. You might also try clear silicone caulk (GE Silicone II or similar) that can be cured into shaped flames, and even tinted with a drop of acrylic paint (red, orange, yellow). To protect the small LEDs (0201, 0402, pico, nano, etc) from having their wires pulled off, a light coat of clear nail polish on the LEDs works pretty good. All the best ...
