Here are the only 97.221 (c) winlink stations the FCC has any jurisdiction over (this is 40 meters ONLY) -- but my data suggested that 40 is the BIGGEST issue, and that even then it is around a hundredth of 1% issue.... 070049Z N5TW EM10CP 7,091.500 KHz WINMOR 500 00-23 Georgetown, TX, USA 070156Z W2GSA FN20WD 7,090.500 KHz WINMOR 500 00-23 Eatontown, NJ, USA 070156Z AJ4GU EM83AL 7,089.500 KHz WINMOR 500 00-23 MCDONOUGH, GA, USA 070049Z NX4AC EM81DD 7,089.000 KHz WINMOR 500 00-23 Moultrie, GA, USA 070248Z W6IDS EM79NV 7,084.500 KHz WINMOR 500 00-23 Richmond, IN, USA 070031Z KB5MAC EM20FA 7,082.500 KHz WINMOR 500 00-23 Houston, Tx, USA 070044Z KP3CR FK68NG 7,082.000 KHz WINMOR 1600 00-23 Lares, Puerto Rico, USA <----this Puerto Rico station may be using too wide a signal!!! A configuration goof. I can send an email to ask about that one......I've caught these kinds of goofs before.... 070105Z WB9FHP EM68SM 7,075.500 KHz WINMOR 500 00-23 Paoli, IN, USA 070049Z N5TW EM10CP 7,066.500 KHz WINMOR 500 00-23 Georgetown, TX, USA 062215Z N5TW EM10CJ 7,066.000 KHz WINMOR 500 00-23 Georgetown, TX, USA 070230Z W0MAC EM20GA 7,066.000 KHz WINMOR 500 00-23 Houston, TX, USA 070301Z AK4SK EM60VL 7,064.000 KHz WINMOR 500 10-05 Freeport, FL, United States Is there a problem with any of those frequencies themselves? My previous data indicated that these sorts of american stations were only used for a hundredth of a percent of the available time/bandwidth..... Doesn't seem like much at all? Maybe there is something I don't understand here. if you are hearing pactor on any other frequencies than those on 40 meters....you're listening to a foreign station, and often US amateurs do appear to have legal rghts to make DX contacts such as those.....although the 3rd party rules can be challenging for other parts of the world.... anyway, would be interested in your response to those freuencies. If there is a real issue with any of them, I suspect a simple phone call would handle it nicely.
