[HCDX] RTTY unIDs on 7455, 9960, 11690

[Glenn Hauser <wghauser@xxxxxxxxx>]

Trying to establish the identity of three long-hours virtually continuous RTTY
transmissions which broadcasters have to (or should) avoid; frequencies might
be slightly different than:

 7455 during darkness hours in NAm
 9960 during darkness hours in NAm
11690 during daylight hours in NAm

First I check the second-quarter ITU monitoring file at 
http://www.itu.int/ITU-R/terrestrial/monitoring/files/pdffiles/310.pdf

And find that they have only noticed 7455, but it is unID for them too. (The
third-quarter file, /311.pdf has not yet appeared). Unfortunately, all of the
ITU monitoring stations are in Europe except for one in Korea. Why not any in
the Americas?? Also note that the columns (in English, not French or Spanish)
are mis-labeled. Column 20 contains the bearing of the station, if determined
(not in the case of 7455).

Searching 7455 in the UDXF yg which has been active for a few months now, only
got these two hits:

06/29/06 05:54z, 7456.0 RTTY/1175/850 encrypted (unusual freq. here)
(Steve Smith, Redwood City, CA, UDXF yg via DXLD)

In what way unusual? Rather fast at 1175 Bauds! It's NATO-75/75/850 and the
frequency is 7455 kHz. Measured in USB mode?? !!!! 73 de (Jim, MPJ, Scotland,
June 30, ibid.)

This was the only hit on 9960:

9960.0 kHz dig unID: KG-84 FSK 850Hz/75Bd encrypted 1029:26 UT (2006-06-17)
(Sferix in Taipei Taiwan on ZIRC:#wunclub)

And there were no hits in UDXF on 11690, nor 11689, 11691.

Also checking the Klingenfuss 2002 SW Frequency Guide: nothing on 11690; 9962
has NPM Pearl Harbor, but I don`t think the frequency is that high; nothing on
7455.

So can anyone determine the source of these three transmissions? Or offer any
clues if they are not openly identified? Thanks, (Glenn Hauser, OK, DX
