Regarding K9UN's request for HF beacon station listings, there are 20m beacons used in a worldwide network sponsored by a big DX assoc. (Northern Calif or some such.) They are at: (slot #, location) 0 New York 1 San Francisco 2 Hawaii 3 Tokyo 4 Israel 5 Helsinki 6 Madiera Isl. 7 Johannesburg, S. Af. 8 Buenos Aires 9 Medillin, Columbia Each transmits for 1 minute at all times which end with the slot #, thus NY at hh00 hh10 hh20 hh30,hh40,and hh50; Tokyo at hh03,hh13,hh23 etc. The system is on continuously. After CW ID they give tones for a few seconds each at 100w output, 10w, 1w and .1w., then a final ID. They operate on 14100 khz, and all are within about 50 hz or so, the CW pitch changes just a little as they cycle through. The start and stop times seem to be controlled to within about 2 seconds of nominal. If one sets a well calibrated HAM receiver with a narrow filter at 14100.0, normally one will hear several of the 10 at just about any time. The South American stations in slots 8 and 9 are new, may not yet be on air. I also have a FORTRAN program that predicts when you should be able to receive them base on the solar_flux. It is a program written by Mort, KA1IU, based on the MINMUF program for predicting the best time of the day from your location to receive these beacons. One mode of the program calculates the MUF for the beacon locations, along with a number of other locations (a total of 21), including WWV in Colorado. The output is in tabular form for hourly time intervals at a selected solar flux level. I tried to send this directly but must have your electronic mailing address wrong. 73, John, K1KSY

john, with regards to your response to k9un, i would really like to have a copy of your FORTRAN program. Would it be possible to mail me a copy. i tried mailing this request to you, but two attempts failed. sorry to post this to the net. thanks, kenb UUCP: ihnp4!sys1!techsup!kenb
