The CARMELO network project, after a year of uninterrupted activity, proved to be reliable and gave us a glimpse of an unpredictable result: the reconstruction of meteor trajectories. After an analysis of the current situation and the models, the first results are shown, especially on simultaneous registrations. These radio recordings, compared with the optical counterpart, demonstrate how much the CARMELO instrument can be exploited for trajectory reconstruction. Finally, the construction of a “local” network linked to its own transmitter is proposed, a solution to overcome the limits imposed by the GRAVES radar. (read PDF full article)

4. Barbieri L. (2023) " The 2023 Quadrantidis"

We present the report on the radio observation of the Quadrantids shower recorded by the CARMELO (Cheap Amateur Radio Meteor Echoes LOgger) network. As in the observations made in previous years, a complex structure is confirmed in which two secondary filaments are evident, before and after the main shower, the second of which appears to be composed of larger mass meteoroids.

3. Barbieri L. (2023) " Le Quadrantidi del 2023"

Presentiamo il report sull’osservazione radio dello sciame delle Quadrantidi registrato dal network di CARMELO (Cheap Amatorial Radio Meteor Echoes LOgger). Come nelle osservazioni compiute in anni precedenti si conferma una struttura complessa in cui sono evidenti, prima e dopo lo sciame principale, due filamenti secondari, il secondo dei quali appare composto di meteoroidi di massa maggiore.

2. Barbieri L., Brando G. (2022) " A global network for radio meteors observers".eMeteorNews, vol. 7, no. 1, p. 34-45

Radio meteor observations have been practiced by few observers in the amateur community using different and sometimes complicated techniques. Based on the experience with RAMBo, the authors have created a device using SDR (Software Defined Radio) technology which measures and records the main physical parameters of the radio meteors by analyzing the meteor radio echoes. The low cost combined with the simplicity of the construction and management makes it suitable for the creation of a global network of receiving stations capable of producing coherent observational data which can be analyzed to study meteor shower activity.
