Overview FlexRadio: Modern Flex 8000 and Aurora radios are ingeniously designed as IP radios, integrating advanced technology that allows the radio interface to function as a sophisticated PC program. This innovative architecture means that the traditional hardware limitations of radios are significantly reduced, enabling a more flexible and versatile operation. Despite this modern approach, many experienced operators have successfully utilized Mumble in conjunction with a Remote Desktop Client, a combination that has been rigorously tested through countless QSOs, amounting to tens of thousands of successful communications. This method has proven to be reliable and effective, showcasing the adaptability of the Flex system in various operating environments. The Flex client operates directly on the desktop where the radio is situated, eliminating the necessity for IP connectivity in this configuration. This setup not only simplifies the connection process but also offers optimal performance of the Flex user interface (UI), ensuring that users can enjoy a seamless and responsive experience while operating the radio. The direct connection enhances the interaction with the radio, making it more intuitive and efficient for operators to manage their communications. However, audio transmission presents another layer of complexity within the Flex ecosystem. Historically, Flex radios have faced challenges related to latency-over-time issues, particularly with the Digital Audio Exchange (DAX) feature. These latency issues have been a concern for many users, as they can disrupt the quality of audio and affect overall communication effectiveness. Fortunately, according to recent reports from the Flex community, these latency problems have been addressed and resolved, leading to improved performance and reliability in audio transmission.
Is it necessary to disclose remote operation during broadcasts?
Per FCC Part 97 regulations, there is no requirement to disclose remote operation when using ham radio. Operators must identify themselves using their callsign in line with standard identification protocols. The control point can immediately terminate transmissions if necessary (which the K0UO station can at anytime, and also has a fail safe). The remote nature of the operation does not impact these identification requirements. Although some operators may opt to mention their remote setup in informal conversations, it is not a compulsory practice. K0UO owns the physical hardware and is simply providing the infrastructure for lease. Because the owner does not profit from the content of what you say on the air, they are not violating the prohibition against "communications for hire". The ARRL and the FCC fully recognize remote operating as a legitimate way to hold an amateur license, provided the remote software immediately cuts the connection and drops the carrier if the internet link fails which, K0UO/R does. [1, 2, 3, 4]
NTIA users under RSI Corp, commercial or DOD/DOW, must follow their requirements for remote access, or the used of the RSI Corp test range site.
Why K0UO went to the big Rhombic arrays
K0UO would have saved a lot of money $$$, time, frustration, and regret, if he had not put up the 200 ft rotating towers, with all the stacked aluminum beams. This was back in the late eighties and 1990s, when his wife moved back to the Kansas Ranch, and he started building the dream station.
For first 15 years on the ranch, was spent each spring, summer, and fall working on mechanical things. It was just non-stop repairs and replacement of components.
Each winter the big Arctic ice and wind storms out on the high open prairies, east of the Rocky Mountains in Western Kansas, destroyed every aluminum or fiberglass antenna that was installed, even the commercial ones rated for 125 mph.
No yagi can bet the very large Rhombic or Curtain Arrays.
