January 6, 1936: "The following is quoted from a memorandum written by the radio technician on the Cumberland National Forest in Kentucky and is an interesting comment on the Ultra high frequency signals from the Radio Laboratory in Portland, Oregon (KBAA). The UHF transmitter at KBAA has a carrier power of less than five watts.
'I happened to be at the Indian Trail tower Saturday afternoon for the purpose of inspecting the F-11 London telephone line and the antenna installation on the tower. While checking the radio set I noticed a station just below our 32.14 mc. channel ----- I therefore listened to the station from about 3:00 p.m. to 3:30 p.m. C.S.T. when the announcement was made that the station was KBAA, the experimental station of the U.S. Forest Service at Portland, Oregon.'
'The signals were heard on set TH 38 which is installed in the Indian Trail lookout tower. Slow fading was noticed, the signal varying in strength from about R6 to R2. The signal strength would be quite good for periods of 3 to 5 minutes and then drop for a period of 15 to 60 seconds. Of course small variations in signal due to fading would not have been noticed because of the automatic-volume-control action of the receiver. The low signal periods were comparatively short however, and the signals were readable about 95 percent of the time during which I listened." (Forest Service Bulletin)
