Fellow programmer, greetings! You are reading a letter which will bring you luck and good fortune. Just mail (or UUCP) ten copies of this letter to ten of your friends. Before you make the copies, send a chip or other bit of hardware, and 100 lines of 'C' code to the first person on the list given at the bottom of this letter. Then delete their name and add yours to the bottom of the list.
Don't break the chain! Make the copy within 48 hours. Gerald R. of San Diego failed to send out his ten copies and woke the next morning to find his job description changed to "COBOL programmer." Fred A. of New York sent out his ten copies and within a month had enough hardware and software to build a Cray dedicated to playing Zork. Martha H. of Chicago laughed at this letter and broke the chain. Shortly thereafter, a fire broke out in her terminal and she now spends her days writing documentation for IBM PC's.
Don't break the chain! Send out your ten copies today!

A few NDB logs
 |
| The NDBs around Otopeni & Baneasa airports (click on image to enlarge) |
During a recent visit to Romania and Northern Greece, I managed to hear a few local NDBs using a Sangean ATS-909 portable radio:
2019-10-29 14:35 349.0 OPE Otopeni, ROM
2019-10-29 14:36 370.0 OTL Otopeni, ROM
2019-10-29 14:37 521.0 BSW Baneasa, ROM
2019-10-29 14:38 256.0 BSE Baneasa, ROM
2019-10-29 14:39 267.5 OPW Otopeni, ROM
2019-10-29 14:40 284.0 GNA Gorna, BUL
2019-10-29 14:41 318.0 OTR Otopeni, ROM
2019-10-30 17:25 345.0 THS Thessaloniki, GRC
The ATS-909 is bulky by current standards and not sensitive in the NDB band, so it is, perhaps, the last time I take it with me.

G3USF's Worldwide List of HF Beacons
The IARU Region 1 beacon coordinator is Martin Harrison, G3USF. Martin is a member, and a past Chairman, of the RSGB Propagation Studies Committee (PSC). He used to maintain two comprehensive and detailed lists of beacons.
The last published version of the worldwide HF beacon list compiled by Martin Harrison G3USF was on May 23, 2018. I have saved it here: G3USF's Worldwide List of HF Beacons for future reference.
The Low VHF (40-50 MHz) beacon list by G3USF is still updated regularly, you may see the latest version here: G3USF's Worldwide List Of 50MHz Beacons.
An alternative 28 MHz beacon list by Bill Hays, WJ5O, is also available and updated frequently here: 10 meter Beacon List.
