RF Output Power in mW of HR12A and SR751A??
« on: January 07, 2023, 01:28:06 PM »

Does anyone know of URLs that would specify the RF power output in mW for the HR12A and the SR751. I have been unable to locate such spec sheets with Google.   Thanks

I looked in the FCC Database.
X10 did not  have any files on the HR12A. That may have had RF data in it. Some do but early unit models X10 didn't provide them for release to the public. I don't think they grave a mW power rating just a chart of the signal strength at a determined distance.
I don't know the SR571A FCC ID so I am not sure if that information is there.

Dave had lots of information on his site but I don't know if it has such data.

I looked at one of the X10 modules with an RF transmitter in it.
There was on output power in mW given.
They did have a test chart. Using measured level @3M. dB micro volts.

< 100mW for Palm Pad. SR751 does not have RF transmitter.
