Check DX Propagation with Beacons
Here is a good way check the propagation and MUF to DX in less than a minute using the Northern California DX Foundation world wide beacon system.
Enter the following frequencies in sequence (low to high) into your radios memory forCW.14100,18110,21150,24930,28200. (You may need to enter a slight offset to hear a good CW tone, like 14199.6, 18109.6, 21149.6, etc.)
If you want to check the propagation and Maximum Usable Frequency to New York, tune in 4U1UN (United Nations HQ in NYC) listen at 0:00 on 14100 kHz, then switch to 18110 at 0:10, switch to 21150 at 0:20, switch to 24930 at 0:30, switch to 28200 at 0:40. You can easily tell which frequency has the best propagation in less than a minute.
If you want to check the propagation toSan Franciscolisten for W6WX at 0:20 past the cycle start time on 14100, Then switch to the next higher band you have stored in your memory bank every 10 seconds and if the next higher band is open you will hear W6WX .
If you have a good Atomic Clock (WWVB) or accurate clock you can identify the beacons without even knowing the morse code. Each beacon has a 10 second slot, They send their call sign (CW at 22 WPM) followed by 1 Dash at 100w, then 3 dashes at 10W, then 1W then 0.1W. If you can hear all the dashes, the band is really open. The 14100 kHz cycle starts at 00 at the beginning of the hour and repeats the cycle every 3 minutes: 00, 03, 06, 09, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57…minutes past the hour.
The sequence of transmissions on 14100 kHz is:
