The 1610 kHz frequency is a real jumble here in western Washington at 
night, but there are a couple of low-powered NOAA weather relay 
stations in Aberdeen, WA and in NE Oregon that might match your 
description. Here in Puyallup (about 30 miles south of Seattle) one 
of these weather relay stations is usually in the 1610 mix at night, 
along with the Yakima WSDOT TIS station or one of the other low 
powered WSDOT relays (and rarely, the 1610-Carribean Beacon station 
from Anguilla, with sermons from the late Gene Scott or his daughter).

Subject: [IRCA] 1610 Time Pips
Last evening while working at the bench, I had 1610kHz running in the 
background...just after local sunset. At both 20 mins and 40 mins 
after the hour, there were 5 very easily-heard time pip second 
markers, but no copy on the station itself....looping E-W at the 
time....any ideas of which station this would be?
