With all the realigning due to the establishment of DHS, I'm not sure this is all still true (Larry Van Horn, help me out here...), but I think our area is covered by NMN Portsmouth, which is actually remoted via NMF Boston.
There are a great many possible frequencies to try, and they even have a dedicated SITOR-B schedule of broadcasts. Some ALE has also been reported. Take a look at the recent newsletter at the
WUN website, then download the free newsletter. Read the Nautical column, then check the logs section. You will find lots of info there.
There are numerous inexpensive packages that will allow you to copy the SITOR-B broadcasts, and even some free software for the ALE signals. Check the
Utility Monitoring Central site (look at the 'software' links) for information on this.
