As the results of my testing has generated more interest I've gathered the links to all the of the various tests.  New tests will be added when they are complete.  Note that I will rarely do any testing November through April, as my test field will be under several feet of snow!

Requests/suggestions for transmitters to be tested may be sent to: ironrangecountry@mail.com.  I make no promises that I will test all requested devices.  Old or generally unobtainable models are of less interest.  Also I prefer to test units that are FCC Certified (or at least claim to be).  All devices tested are always purchased through regular retail outlets with no involvement or knowledge of the manufacturers.

For those technically inclined the equipment used for testing includes (but is not limited to)

Potomac FIM-71 field strengh meter with it's calibrated ANT-71 antenna

Z-Technology R-506 field strength meter with it's calibrated antenna

(both these devices are commonly used in the field by the FCC)

Inovonics 531N Modulation Monitor

Coaxial Dynamics Watt Meter with CD Custom manufactured 100 mw and 1 watt FM band "slugs"

Rigol DSA 815 TG Spectrum Analyzer

Tektronics Oscilloscope (when necessary)

Details of testing proceedures are generally outlined with each test paper.

One short addendum to the Whole House 3.0 part of the above tests. "Update: October 2016, I tested 5 WH 3.0 units back to back, all within a minute or two of each other, under identical conditions.  Of the 5, field strength at 3 meters ranged from a low of 5635 uV/m to a high of 7585 uV/m.  Remember, legal is 250 uV/m."
