A couple of days ago I was monitoring 6712 kHz.
The frequency is listed for Reykjavik Ground station, but on the air was Krasnodarsk Ground station.
As was not enough strange, on the same frequency a lady was dictating numbers... No, it was not a "Numbers station" in the classic mean. It sounds more like a network controller...
At the top, was a Jamming signal...
After a few minutes, the lady ceased transmission and Reykjavik GS was back on the air!!!
Very strange!
Here is a record.

Air traffic on 5655kHz
This evening, as usually, I was monitoring 5655kHz for some air traffic.
And there it was!
I was able to receive and decode HFDL from HAT-Yai Airport from Thailanda.
What was very unusual was that, on the same frequency, I was able to hear some USB Phone operations.
Anyway, It was impressive that the signal was very clear and noiseless!

Romanian Numbers Station
Putini sunt cei care isi arata preocuparea pentru asa numitele "Numbers Stations" la noi in tara.
Sub aceasta titulatura se ascund anumite emisiuni destinate agentilor care opereaza in tari straine, sub acoperire.
Tehnic vorbind, este vorba de un emitator, de regula in gama undelor scurte, ce transmite siruri de cifre, prearanjate dupa un anume algoritm, intr-una din gamele de frecventa folosite de emitatoarele de radiodifuziune comerciale sau nationale, de regula in modulatie de amplitudine sau in modulatie cu o banda laterala suprimata.
Sirurile de cifre reprezinta un mesaj criptat printr-o metoda de unica folosinta (tabla de criptare).
Mesajul este adresat unui agent care detine tabela unica de decriptare si care, prin folosirea acestiea, recupereaza mesajul.
Principalele avantaje ale acestei metode de comunicare (unidirectionala) sunt:
-posibilitatea ca agentul sa preia mesajul indiferent unde se gaseste pe teritoriul strain;
-absenta riscului generat de posesia unor mijloace specifice de comunicatie cu centrala de operatiuni;
-rezistenta la penetrare a codului folosit.
Ce se stie mai putin este ca si Romania a folosit astfel de metode de transmitere a mesajelor catre agentii sai din strainatate!

RACAL Panther 2000-V - Tactical radio
This is how it sounds!
The Panther V Enhanced Data Radio (EDR) is a core element of the latest generation Panther EDR frequency hopping military radio family. It represents the smallest and lightest tactical 20 watt manpack and vehicle radio available today, offering un-paralleled Electronic Protection Measures (EPM), data and user capabilities in the 30 to 108 MHz military radio band.
Panther V, although available as a 20 watt manpack, has co-site filtering built in to the basic transceiver. By connecting the radio directly to the 24-volt vehicle supply, Panther V will operate as an extremely compact 20-watt vehicle station in multi-radio installations. For higher power, Panther V connects to a vehicle interface unit providing a power output of 50 watts. Even in this high powered role, the volume of Panther offers considerable savings over similar radios from its nearest competitors.
PANTHER V-EDR - GENERAL DESCRIPTION- Operating in the 30 -108 MHz frequency range, Panther V-EDR offers unsurpassed communications performance for a radio a fraction of the size and weight of the current generation of equipment.
- The Panther V-EDR which is now in service in many countries around the word, has been described as the easiest to use tactical VHF EPM radio available today. Fully automatic initial and late entry synchronisation in all EPM modes, coupled with the user friendly controls, ensures that communicating is easy and reliable even for inexperienced operators.
- Essential to multi-media radio networks is an on-air management system able to provide voice priority and maximum throughput of data at the same time. Panther EDR has been designed with built in multiple radio access protocols, allowing integrated voice and data throughput on a radio net. Carrier Sense Multiple Access (CSMA) automatically controls data flow across a radio network and is essential for managed mixed voice and data networks.
- The advanced facilities provided in the new Panther V-EDR further simplify end enhance the radio s operation, including the introduction of a full dot matrix alphanumeric display for mode indication, easy to use menu structure, and programmable radio net names.
- The Panther V-EDR radio incorporates the very latest in Digital Signal Processing technology providing a truly software configurable digital architecture radio design. This means that the flexible design and processing power available will ensure that future upgrades, to meet specific operational requirements, can be achieved throughout the in service life of the radio. Software upgrades are achieved without the need to open the radio, thus ensuring that future requirements can be met in the field.
- To achieve the compact design and high reliability of the radio, comprehensive use of surface mount technology has been made with over 95% of the components being SMDs.
- The Panther V-EDR radio provides the option for seamless transfer of GPS position information from the externally connected GPS receiver (Internal option available for PANTHER V-EDR GPS). Position information is available on request (polled) or sent with each transmission. By embedding the position coordinates within the encrypted on air link protocol, the information is completely protected from enemy intercept, and additionally is transparent to the radio's voice and data transmissions.

INTEGRATED COMMUNICATION SYSTEMS
THE ULTIMATE MANPACK SOLUTIONThe Panther V - EDR is a core element of the latest generation Panther Enhanced Digital Radio (EDR) family. It represents the smallest and lightest tactical 20 watt manpack and vehicle radio available today, offering un-paralleled EPM, data and user capabilities in the 30 to 108 MHz military radio band.
THE COMPACT VEHICLE SOLUTIONThe Panther V - EDR manpack transceiver provides 5 and 20 watts of RF power with un-matched co-site capability enabling operation in multi-radio locations where the majority of similar manpack radios would fail. The transceiver's superior co-site performance also enables the manpack to be operated in a vehicle clip-in configuration, with colocated 50 watt VHF radios, delivering up to 20 watts through the vehicle antenna.
The Panther V- EDR transceiver can be installed as a dedicated compact 20 watt vehicle radio in land based tracked and wheeled vehicles as well as airborne and naval platforms. Vehicle harness interfacing and power conditioning have integrated within the transceiver, thus providing a single unit solution.
For high RF power vehicle and base station operation, the Panther V - EDR transceiver interfaces to the BCC 767 amplifier unit providing 50 watts in a compact size that similar systems have been unable to achieve.
