Hi John Section 15.209 has general requirements for radiated emissions for intentional radiators (transmitters). At these frequencies you would be allowed 200 uV/m at 3m, not much but you aren't allowed higher power until you get to 902-928 MHz band. best regards Tom On Mar 12, 2013, at

Hi Ravinder Try F.W. Bell, recently bought by Meggitt PLC. I saw a probe there that goes DC - 450 kHz, but you should contact them with your specific requirements since they have many combinations of frequency range and sensitivity. http://fwbell.com/default.aspx Good luck. best regards

Re: [PSES] OATS vs FAR Radiated Emissions Limits

Amen to that. In 1981 FCC lab set up a demo room. We had TVs and radios tuned into local stations. The emissions from one of those (not yet regulated) luggable inventory recorders used in convenience stores and the like would completely wipe out both picture and sound at Ch 5. The

Re: [PSES] OATS vs FAR Radiated Emissions Limits

The US had limits on other unintentional radiators since at least the 50s: low power AM transmitters, TV and radio receiver oscillators, garage door openers For a long time (I think since the 30s) there was a generic limit of 15 uV/m at a distance of lamda/2pi, most of the low power AM TXs I
