Yes, I confirm NDB RPK is keying poorly and with a chirp. I have the USB at +1005 Hz with a repeat period of 6.60 sec. Other NDBs I copy on the frequency are: TO at +985Hz, 5.84s, Topeka, KS; GM at +991Hz, 6.14s, Greenville, SC; DWH at +1010Hz, 5.94s, Houston, TX; and ORC at +1052Hz, 6.97s, Orange City, IA. -- 73, Garry, K3SIW, EN52ta, Elgin, IL
