G+_Eddie Foy Posted July 27, 2016 Share Posted July 27, 2016 Well its either bad RF emissions, safety issues, longevity issues, or lead and lead based paint from the cheap Chinese junk we all love. Don't need quality in the disposable era. CFLs wrecked havoc on HF here. LEDs seem a lot better. Link to comment Share on other sites More sharing options...
G+_Jason howe Posted July 27, 2016 Share Posted July 27, 2016 Likely a number of things causing RF Over/under current a nail through telco cable. Ungrounded co-ax.. Fluro lights Dimmers Mobile phones Security products Beacons Ir and Bt devices.. Wifi. Lite/4g/3G/WiMAX/sat Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 28, 2016 Share Posted July 28, 2016 Yup. But FCC has limits on allowed RF emissions. This ballast fails. Link to comment Share on other sites More sharing options...
G+_Jason howe Posted July 28, 2016 Share Posted July 28, 2016 Yup sad to say LTE itself can operate within 700 MHz through 3.2-3.8 ghz on cell bands Wifi/WiMAX can operate as low as 600 MHz-5.8 GHz New kids on the block air fiber 24 GHz Satellite 850 MHz - 5.8 GHZ which can be higher once you add 2-way hardware services.. Fttn/fttn. No matter what there is out there things will conflict with everything.. Link to comment Share on other sites More sharing options...

G+_Tom Justtom Posted July 29, 2016 Author Share Posted July 29, 2016 My HAN club has been talking allot about these.apparently they are causing a lot of RF interference. Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 29, 2016 Share Posted July 29, 2016 Poor PCB design, bad isolation, leaky cheap caps, inconstant transformer winding, poor shielding. Link to comment Share on other sites More sharing options...
G+_Tom Justtom Posted August 5, 2016 Author Share Posted August 5, 2016 The point was to not use or recommend using them. Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted August 9, 2016 Share Posted August 9, 2016 Not to. Throws off RF/EMI outside of acceptable levels. Link to comment Share on other sites More sharing options...
G+_Tom Justtom Posted August 9, 2016 Author Share Posted August 9, 2016 Correct. They are jamming HF Link to comment Share on other sites More sharing options...
