Well, this Solar Array was put up with a City Permit and I requested the Permit & Info to be able to identify the Company, Installer & Owner. Will see if any of my RFI measurements, Waterfalls, and T
For those ( RFI Engineers, etc ) that want to learn more about RF EMI at all frequencies from these Solar Array and Inverters look at this link, very interesting See link below https://core.ac.uk/dow
Wonder what Solar City/Solar City do next move will be ? 73 Mike Possibly got same issue here, but RFI Solar Panel is 700 feet away from my location. Heard 6 blocks away from QTH 1. This is great new
Well, the SolarEdge Inverters that have the Power Optimizers use Buck Boost Converters which can be very Noisy and generate spurs. Designed a Microwave Receiver with these Buck Boost HV Converters an
Jim, Yes, i seen the high efficiency buck boost HV converters increasing the IF Noise floor in Microwave Receiver's by spewing RF Hash into the MHz region. Good design & Filtering fixed this ! Not go
Well, if it is on a 18hr on/6hr off cycle or 12hr on/12hr off cycle could be Grow Lights, The new HV lights spew tons of RF carriers in the 6MHz to 8MHz Region, not like the earlier lights that gave
Have you tried an Input AC Line EMI Filter on the Amplifier Assume you using 220VAC Use a Dexicon LC2KVA for 220VAC at 10amps ( Surge, Transient and EMI Filter with SoftStart & Noise Reduction Featur
Well, this my Dexicon rated at 220VAC 15Amps RFI/EMI Filter on my input of my TL-922A, works well ! https://www.ebay.com/itm/AC-EMI-RFI-Noise-Filter-Line-Cleaner-220-240VAC-15A/140524915215?epid=2036
The Isobar 110VAC EMI Filters on your Home Theatre and Net Boards might also help. https://www.ebay.com/itm/Tripp-Lite-Isobar-6-Outlet-Surge-Protector-w-Tel-Fax-Modem-Protection-3300-J/381632896929?_
I use to use an OCF dipole, got rid of it, too much RFI into AC mains ! 73 Mike Michael Aust ava622@verizon.net Yes, A Windom, that is coax fed into a 4:1 balun. Remember, I did *NOT* have this issue
Did some serious research, This RFI group has it all wrong, it's not HF HAM Bands ! The Author from REUTERS is full of it, FAKE NEWS , it is not HF HAM Amateur Radio frequencies https://www.reuters.c
