Orrin Elmer Dunlap, Jr., The Radio Station of Orrin E. Dunlap… (1916)
“ Although the weather conditions for amateur radio work have never been over good in this section of the country, I have picked up quite a few distant amateurs this year. Among them are, 9NN, 9SP, 9UC, 9DB, 1ZR, 1ZL, 1ON, 1ZM, 1ZW, 2ZP, 2SX, 2PV, 2DL, 2LK, 2DA, 3WN, 3FR, 3NB, 8ALE, 8WW, 8OU, 8XA, 8NH, 8AMX, 8ER, 8MW, 8MC, 8JK, 8BK, 8RV, 8JX, 8CX, 8DX, and 8NQ. The majority of times when transmission seems at its nest are nights when it is rather warm, thirty to forty degrees. ”
