Long Wave Beacons in Wisconsin

This page contains two lists of all the longwave beacons in Wisconsin of which I am aware. The first list is organized by frequency, and contains data concerning on-air status:

"on" means that I have heard the beacon in my own listening, whether at home or on the road, some time within the past five years or so.

"off" means that I have tried to hear the beacon while near its location and did not find it active.

"?" means that I do not have any current information on the status of this beacon.

An asterisk means that I (or a contributor) have heard the station on the air, or heard it not on, since 1 May 1998.

The second list places the beacons in alphabetical order of location.

Longwave Notes:

10 April 2014: The transmitting equipment of silent BL 260 Milwaukee, located across the street from Bradford Beach, was taken down and removed this week.

18 March 2014: RF 275 Rockford IL noted on, from a transmitter in Ogle county.

13-14 August 2013: Traveling in central Wisconsin, I noted these beacons on the air: ISW 215 Wisconsin Rapids, DW 266 Marshfield, CW 275 Mosinee, EK 326 Wisconsin Rapids, PCZ 382 Waupaca, MFI 391 Marshfield, OS 395 Oshkosh. Listening near the transmitter, FZK 243 Wausau was noted not on.

July 2013: I noted these Illinois beacons on the air while on the road: FWC 257 Fairfield, AAA 329 Lincoln, CZB 359 Casey, SYZ 365 Shelbyville, LQ 375 Springfield, SP 382 Springfield, CIR 397 Cairo, PLX 391 Robinson, SLO 400 Salem, and CM 407 Champaign

24 May 2013: I visited the transmitter site of RYV 371 Watertown WI, located adjacent to Watertown Municipal Airport on the south side of Boomer Street; the beacon remains active.

27 Mar 2010: In Appleton, I noted AQ 407 active, and found its transmitter S of Natures Way at Tracey St, but did not hear AT 230. MT 362 Manitowoc remains active, as do SG 332 and GR 356 in Green Bay. In Sturgeon Bay, II 224 and SUE 414 are listed at the same coordinates, but I did not see the transmitter at that site, and found II on, but did not hear SUE.

25 Jun 2009: Listening in Cedar Rapids IA, I noted that CI 326 Cedar Rapids is not on, and did not hear AJP 287 Marion nor VTI 338 Vinton. UOC Iowa City, which was on 524 and supposed to move to 349, was heard on neither frequency. AL 382 Waterloo remains on.

1 Aug 2007: Monitoring beacons in the daytime from Oak Creek I made a few observations. Four nearby beacons were noted missing: Milwaukee's GM 242, BL 260, and MK 298, and UES 359 in Waukesha. There was a strong open carrier on about 305. New catches included MT 362 in Manitowoc, a beacon previously unknown to me (and now added to this page) and the surprisingly distant DFI 246 from Defiance OH.

8 Aug 2005: GM 242 Milwaukee is now IDing as MT. Thanks to Gary Timm for noticing this.

14-19 July 2003: Some notes on beacons in southern Illinois. Noted on: BDD 254 Brookport, CIR 397 Cairo, MD 388 Carbondale, HSB 230 Harrisburg, MW 382 Marion. Not heard: MIX 281 Metropolis, BEE 414 Benton. In Mattoon on 347 I heard NE, not MT, and in Greenville, I heard SLO on 233, not GRE.

17-19 March 2003: Visiting Minnesota, we noted these beacons on the air: HCD 209 Hutchinson, ULM 272 New Ulm, and ACQ 371 Waseca. ACQ carried voice weather.

2 January 2003: Monitoring beacons in Davenport IA, I found the following on the air: ML 215 Moline IL, DV 353 Davenport, CWI 377 Clinton IA, and FN 517 Clinton. BBC 224 Davenport is apparently not active, and I did not hear MUT 272 Muscatine IA, but perhaps I was just too far away.

29 July 2002: AMW 275 Ames IA noted IDing as IKV, in an apparent call change.

6 June 2002: GM 242 Milwaukee heard recently with code only, apparently having dropped voice weather (Kent Winrich)

18-20 March 2002: While in central Illinois we noted that the following beacons were active: 236 CTK Canton, 275 DE Decatur, 356 PI Peoria, 375 LQ Springfield, 382 SP Springfield, and 407 CM Champaign. I tried to hear 281 HMJ Homer from Urbana, and did not.

27 June 2001: UOC Iowa City IA noted back on the air on 524, not 349 (Rick Dau)

11-15 June 2001: On vacation in northern Minnesota, we noted these beacons on the air: AIT 397 Aitkin, MD 371 Bemidji, BR 251 Brainerd, COQ 335 Cloquet (code only; had voice in a 1993 check), CKN 400 Crookston with voice weather, GP 272 Grand Rapids, IN 335 International Falls with voice, LXL 359 Little Falls with voice, XCR 404 Little Falls, JMR 327 Mora (here, not on 216, with voice; code not audible in lightning static), PK 269 Park Rapids, SAZ 257 Staples, HY 260 Thief River Falls, and SW 360 Warroad. The following were not heard while nearby: HSK 391 Hackensack and RAD 397 Warroad. In Wisconsin, RIE 407 Rice Lake was noted not on, as in 1999, though I did hear it in 1996.

19 May 2001: Rick Dau reports that UOC 524 Iowa City IA is off the air, and that it is not audible on 349 (to which it was to move) either.

12 May 2001: Bill Dvorak notes that Springfield IL beacons LQ 375 and SP 382 are both active.

25 September 2000: MK 298 Milwaukee is not running an open carrier, but is actually transmitting RTTY, from the Coast Guard station at Jones Island (John Wilke)

10-14 July 2000: During our trip we noted EY 209 Indianapolis on the air; it was not heard while in town in 1995. But HFY 318 there was not heard, but was noted in '95. The "Barbara Ann" beacon, OQ 219 Indianapolis, remains on. DTG 344 Dwight IL was not heard while in town.

19-22 June 2000: On vacation we noted that the following beacons in northwest Lower Michigan are active: CVX 222 Charlevoix, CXK 251 Bellaire, BFA 263 Boyne Falls, CAD 269 Cadillac, and TV 365 Traverse City. We were close enough to believe that these beacons were not on the air: FR 291 Frankfort and CR 302 Charlevoix.

21 March 2000: Visiting the area I noted that CHU 209 Caledonia MN is active. And it's not a time signal!

5 November 1999: While in Fond du Lac I noted FLD 248 still not on the air.

3 August 1999: I checked the two Racine beacons while in town. RA 206 was on with code, and RL 294 was not on.

14 July 1999: While in Milwaukee I note that MK 298 is still on the air with open carrier only.

22 June 1999: I note that UOC Iowa City remains on 524, though I read that it was to move to 349.
