The software provides functionalities for scheduled recordings, enabling automated capture of content at predefined times. It caters to a range of users, from radio enthusiasts monitoring air traffic and scanner amateurs archiving communications, to professional environments requiring 24/7 broadcast storage or call center monitoring. The Pro version extends these capabilities for more demanding, continuous operational tasks. Compatibility spans multiple Windows operating systems, from Windows 9x up to Windows 10, ensuring broad usability across different system generations.

Capturing intermittent radio transmissions efficiently requires a robust audio recording solution that can intelligently manage disk space. Scanrec, a freeware Windows application, addresses this by providing a **Voice Operated Exchange (VOX)** control feature, enabling the recorder to activate only when audio signals exceed a user-defined threshold. This functionality is particularly effective for **FM communications** due to their strong squelch characteristics, minimizing recordings of static or noise. The software supports recording radio communications, air traffic control, and infrequently active channels, preserving disk space by pausing when no sound is detected. It incorporates an anti-clipping feature to ensure the beginning of audio events is not lost, a common issue with mechanical VOX systems. Output files are saved in WAV format, compatible with standard Windows Media Player. Scanrec operates on older Windows systems including Win95, Win98, NT, W2000, and XP, requiring minimal resources like a 486 PC, 4 MB RAM, and a sound card with line or microphone input. While optimized for FM, its VOX gate can be challenging to set for HF ham bands and World Band radio due to their poorer signal-to-noise ratios.

Constructing a compact, two-band magnetic loop antenna for HF operation, especially from constrained locations like a balcony, presents unique challenges. OK1FOU's design, inspired by DJ3RW's 50 MHz loop, addresses these by employing an unusual side-fed configuration and placing the symmetric, two-section variable tuning capacitor at the bottom of the loop, directly connected to the coax shield. The article provides specific material recommendations, including two 1-meter wooden pales and about 3 meters of thick loudspeaker cable, noting the high current (60A at 100W) in the loop. Construction steps detail forming two turns with a 5 cm gap, using a GDO to pre-tune the open loop to a frequency slightly above the desired highest band, and then integrating the tuning and coupling capacitors. For 10/14 MHz, an open loop resonance of 16-17 MHz is suggested. Practical experience with the 10 MHz band from a third-floor balcony in Prague (JO70GC) shows a 1:1 SWR across most of the band without an external ATU. While DX traffic was modest due to the urban environment, QSO examples with RA6WF, LA6GIA, G0NXA, and LZ1QK on 10 MHz are provided, demonstrating its operational capability.
