Mark,
If you mean that you hear a carrier with only a repeating beep on the Putnamville 162.400 transmit site: that indicates the system has lost its feed from the NWS office.
http://www.nws.noaa.gov/nwr/outages.php does not list that site as currently out of service. However it may have been fixed in the last few hours since your post.
There is another issue with certain midland receivers beeping during the weekly test. I assume that is not related since the weekly test takes place on Wednesday.
If the above does not answer your question please state it more clearly.
