The Granger Model 911 ionospheric sounder systems were operated during 1966 and 1967 at six sites in Thailand ranging between about 7 and 19 degrees North geographic latitude geomagnetic field dip angles from 5 degrees S to 20 degrees N. This report presents the results from scaling the vertical- incidence ionograms obtained for foF2, hF2, foF1, hF1, foEs, hEs, and percentage of occurrence of Es and spread F. A comparison is made between foF2 values scaled from the Bangkok C-234 sounder and the Granger sounder for two brief periods--6 April through 7 May 1966, and 1 June through 19 June 1967--when both equipments were operated at the same site.
