The latest Milcom Files - TSM Milcom edition eBook is available now on Amazon at

All his early MT columns have been published in two eBooks. The first two books in the Milcom Files series cover his columns published in Monitoring Times and are available at Amazon.

Book one of The Milcom Files covers the columns published from 1998 to 2006 and sells for US$5.99 at https://www.amazon.com/gp/product/B077NN7RQ5. Book Two in the series covers the period 2007 to 2013 and sells for US$6.99 at https://www.amazon.com/gp/product/B077NQXH3C.

In 2017 Larry joined the Spectrum Monitor writing staff to continue his efforts to chronicle military communications in a new monthly TSM Milcom column.

His first TSM Milcom Archive eBook, the third book of the Milcom Archive series was published at Amazon in May 2019 and is available at https://www.amazon.com/Milcom-Files-Spectrum-Monitor-2017-2018-ebook/dp/B07RN1ZGLJ/ for US$4.99.

This third eBook in the series incorporates the first two years of his TSM Milcom columns written from September 2017 to the end of 2018. These Milcom columns documented HF military frequencies (both foreign and U.S.), and VHF/UHF spectrum military frequencies, mostly for U.S. based monitors. This third book in the series has over 200 pages of frequencies, call signs, monitoring tips, and how-to style articles.


Given recent international events and natural disasters, most radio listeners quickly learn that when the world is in crisis the military will usually be the first organization called upon to intervene. It pays to monitor military frequencies when international events heat up. Monitoring the military can offer some of the most productive and rewarding listening you will ever experience using your radio. The good news is you do not have to live close to a military installation to hear these communications. But you do need to learn where and when to tune in military communications.

Mention the words "Monitor the Military" and most radio hobbyists will immediately think of military air shows, military aircraft flybys or a whole host of other activities that can be heard via radio frequencies. There is a big radio frequency spectrum out there to monitor but if you know where to listen, and some cases when to listen, you can eavesdrop on some of the most fascinating radio communications you will ever hear on a scanner or shortwave radio.

If you are interested in monitoring military communications, own a scanner, shortwave radio, or have an Internet connection for web software-defined radio (SDR) monitoring, the Milcom Archive Files are a must reference on your radio shack shelf.

Larry Van Horn N5FPW, has been a radio hobbyist for more than 55 years listening to world events and monitoring military radio communications. He has spent over 33 years documenting activity in the military radio spectrum in his monthly Satellite, Utility World, and Milcom (Military Communications) columns in the pages of Monitoring TimesSatellite Times, and The Spectrum Monitor magazines. During this time, he has published a treasure trove of military communication monitoring information.


This book is being released internationally. Amazon customers in the United Kingdom, Germany, France Spain, Italy, Japan, India, Canada, Brazil, Mexico, and Australia can order the eBook from Amazon websites directly servicing these countries. All other countries can use the regular Amazon.com website.

Shazam Style Automatic Signal Identification Via The Sigidwiki Database

Fingerprinted Audio Samples of Radio Signals


This is a really interesting development for the digital modes monitors.

Check out https://www.rtl-sdr.com/shazam-style-automatic-signal-identification-via-the-sigidwiki-database/?fbclid=IwAR1okj7C86sJFLzhi7co7Ye-WPBipWaBSXOnlAy4PFUqIiDKslClesn0g1g

Thank you to José Carlos Rueda for submitting news about his work on converting a "Shazam"-like Python program made originally for song identification into a program that can be used to automatically identify radio signals based on their demodulated audio sounds. Shazam is a popular app for smartphones that can pull up the name of any song playing within seconds via the microphone. It works by using audio fingerprinting algorithms and a database of stored song fingerprints.


Using a similar algorithm to Shazam, programmer Joseph Balikuddembe created an open-source program called "audio_recogition_system" [sic] which was designed for creating your own audio fingerprint databases out of any mp3 files.
José then had the clever idea to take the database of signal sounds from sigidwiki.com, and create an identification database of signal sounds for audio recognition_system. He writes that from his database the program can now identify up to 350 known signals from the sigidwiki database. His page contains the installation instructions and a link to download his pre-made database. The software can identify via audio that is input from the PC microphone/virtual audio cable or from a file.

Highlights of Solar and Geomagnetic Activity 13 - 19 January 2020

Solar activity was very low. The solar disk was spotless. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels throughout the reporting period.

Geomagnetic field activity was quiet with an isolated period of unsettled conditions on 16 Jan under a nominal solar wind regime.

Forecast of Solar and Geomagnetic Activity 20 January - 15 February 2020

Solar activity is expected to remain at very low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 21-22 January, due to recurrent CH HSS influence. Moderate levels are anticipated for the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on 20-21 Jan with unsettled conditions forecasted on 22 Jan and 01-05 Feb due to recurrent CH HSS activity.

Highlights of Solar and Geomagnetic Activity 30 December - 05 January 2020

Solar activity was very low. New Region 2755 (S34, L=355, class/area Bxo/020 on 03 Jan) developed on the SE limb on 01 Jan but was in decay by 04 Jan. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 30 Dec-04 Jan. Moderate levels were reached on 05 Jan with a maximum flux of 245 pfu observed at 05/1800 UTC.

Geomagnetic field activity was at quiet levels on 30 Dec-02 Jan under nominal solar wind conditions. On 03 Jan, total field increased to 10 nT at 03/0505 UTC with solar wind speed increasing to around 410 km/s. On 04 Jan, a prolonged period of southward Bz was observed reaching a maximum southward deflection of -4 nT. On 05 Jan, total field increased once again to 15 nT at 05/1743 UTC followed by an increase in solar wind speed to near 550 km/s as a negative polarity coronal hole high speed stream (CH HSS) became geoeffective. The geomagnetic field responded with isolated unsettled periods on 03-04 Jan and quiet to active levels on 05 Jan.

Forecast of Solar and Geomagnetic Activity 06 January - 01 February 2020

Solar activity is expected to continue at very low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels on 08-14 Jan and 23 Jan-01 Feb. Moderate levels are expected on 06-07 Jan and again on 15-22 Jan.

Geomagnetic field activity is expected to reach unsettled levels on 08-10 Jan and 01 Feb. Unsettled to active levels are expected on 06 Jan and14-15 Jan due to recurrent CH HSS effects.

Highlights of Solar and Geomagnetic Activity 23 - 29 December 2019

Solar activity was very low. New Region 2753 (S29, L=122, class/area Bxo/010 on 25 Dec) developed on the visible disk on late on 23 December while Region 2754 (N25, L=191, class/area Axx/010 on 25 Dec) developed on 24 Dec. Both regions were inactive and decayed to plage on 26 Dec. No Earth-directed CMEs were observed during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 27-29 Dec and reached moderate levels on 23-26 Dec. The maximum flux of the period was 462 pfu observed at 25/1810 UTC.

Geomagnetic field activity ranged from quiet to unsettled levels. A slight enhancement in solar wind parameters occurred beginning late on 25 Dec as a weak negative polarity coronal hole high speed stream (CH HSS) became geoeffective. Total field increased to a maximum of 9 nT at 25/1920 UTC while solar wind speed reached a maximum of 415 km/s at 26/1435 UTC. The geomagnetic field responded with an isolated unsettled period early on 26 Dec.

Forecast of Solar and Geomagnetic Activity 30 December - 25 January 2020

Solar activity is expected to continue at very low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels on 06-14 and 23-25 Jan while moderate levels are expected on 30 Dec-05 Jan and 15-22 Jan.

Geomagnetic field activity is expected to reach unsettled levels on 30 Dec-01 Jan due to weak CH HSS activity. Unsettled to active levels are expected on 14-15 Jan due to recurrent CH HSS activity.
