Shortwave utility station, HFT, 350 Hz tones, Morse ID WM2ZXV, 15 February, 2026, 1724 UTC

Описание: This is shortwave utility station related to High Frequency Trading (HFT).

This signal, and variations, has been around for several years. It has long been thought to be one of the many HFT waveforms that have cropped up in the last 10 or so years. For the average listener, this was hard to prove or disprove.

Most of the US based HFT "experimenters" have been operating under an FCC granted ID exemption. The argument for the exemption was that the waveforms and hardware used to generate the waveforms were incompatible with the ID requirement. This is an odd argument, since the very similar waverforms, and identical equipment, of the Canadian HFT sources have been able to ID in Morse for years.

Recently the FCC canceled the ID exemption for many (possibly all, but I do not know) of the US HFT experimenters. Correspondingly, since roughly 1 January, 2026, many of the waveforms that did not ID for years, have been IDing, allowing confirmation of the sources that were suspected, but not confirmed, in the past.

Recorded at my location in the Mojave Desert of California, USA, on 15 February, 2026, at 1724 UTC.

Disclaimer: Many of the radio reception recordings on this Youtube channel pertain to unusual, uncommon, unknown, or mystery signals that might be found on radio, both shortwave and VHF/UHF. Among the subjects covered are numbers stations, utility stations, military transmissions (both in the clear and encrypted / encoded), aviation, maritime, ham radio, CB radio, radars, ionosodes, propagation beacons, ditters, dashers, whistlers, and just about anything else that might transmit, in any mode, USB, LSB, CW, Morse Code, FM, AM,FMCW, LFMCW, etc. Think of it as SIGINT (signals intelligence) / COMINT (communications intelligence) / ELINT (electronic intelligence) lite, the hobby version. All the recordings are made by me, most often at my home. Although there are a few mysterious things to be found here, you will not find anything paranormal, extraterrestrial, spiritual, or mystic. However, everyone can have their own interpretations of the sounds heard, make of it what you will.
