Normal state when the device is connected: the PLL is LOCKED with an output power of 0.85W and a PLL phase of 2.33V

This shows what happens if the device loses its lock. We simulated a failure by placing our fingers on the oscillator coils.

This shows the return to normal with the user command FREQ:106.7 typed in the input box below. A value between 87.5 and 108.0 MHz can be set.

After pressing 'Send:' the display returns UPDATED FREQ 106.7 along with other technical information. This causes the transmitter to change frequency.

This shows another command, RDS-PI:ABCD typed for devices with the RDS card.

After pressing 'Send': the display returns UPDATED RDS-PI:ABCD instantly updating the RDS PI code.

This shows two additional examples of RDS commands:
RDS-TEXT:[write your message here]
RDS-PTY:[number from 0 to 31]
Text is plain ASCII up to 60 chars and valid PTY Codes shown below.

Shown below are the current commands available for USB PC Control and also the PTY codes for program type. We will be making further developments, improvements and more useful commands to this app in the near future. Keep checking this page for details.

◼ DEVICE-ID
◼ STATUS
◼ FREQ:[87.5 to 108.0]
◼ DDS-ADJ:[-1,0 or 1]
◼ PWR:[0 to 1]
◼ RDS-PTY: [0 to 31 list of PTY codes]
◼ RDS-PI: [0000 to FFFF]
◼ RDS-TEXT:[any string up to 60 chars.]
◼ RDS-ON

Additional commands following Oct 2025 firmware update

◼ RDS-PS:[any string up to 8 chars.]
◼ RDS-MS:[0 or 1]
◼ RDS-TP:[0 or 1]
◼ RDS-TA:[0 or 1]
◼ RDS-AFNUM:[0 to 15]
◼ RDS-AF:[Up to 15 freq. formatted eg. 88.1, 88.7, 94.8]

Stay connected to your transmitter anywhere, anytime. With AAREFF’s remote control option, you can monitor and manage critical performance data in real time without needing to travel to site.

• Web Interface & Secure Login – access your transmitter from any browser
• Real-Time Monitoring – forward/reflected power, VSWR, temperature, and supply voltage
• Remote Control Functions – switch RF on/off, adjust power levels, change and fine tune the frequency
• Flexible Connectivity – connect easily via LAN, VPN, or our secure web interface — designed to work even behind firewalls.

This feature not only gives engineers the tools they need, but also provides peace of mind for station managers by reducing downtime, lowering maintenance costs, and ensuring your broadcast runs smoothly 24/7.

What You See in the Remote Dashboard

The AAREFF remote control interface provides engineers with a complete overview of transmitter and system status in real time:

• Connection & Device Info – online/offline status, LAN & external IP, device ID
• System Performance – CPU load, processor type, disk usage, memory load, lock status
• Operating Conditions – internal temperature, supply voltages, calibration states
• Transmitter Parameters – frequency, forward power, VSWR, phase voltage, DDS/PLL control
• Real-Time Alarms – instant alerts when parameters go out of range

From anywhere in the world, you can securely monitor, troubleshoot, and control your AAREFF / Veronica FM transmitter, ensuring maximum uptime and peace of mind.

Internal Microprocessor Logging

Every AAREFF / Veronica transmitter is supervised by an embedded microprocessor that continuously records system activity. The internal log provides engineers with precise, time-stamped updates of operating conditions and broadcast data.

• Time-Stamped Events – detailed logs of all changes and updates
• Operating State – PLL lock status, frequency, RF power output
• Live Parameters – phase voltage, VCO levels, calibration values, DDS registers
• Device Information – unique transmitter ID and system identifiers
• Configuration Updates – records frequency adjustments and parameter changes
• RDS Activity – logs text messages, program IDs (PI), PTY codes, and 57kHz carrier status
• Diagnostic Data – low-level register outputs for troubleshooting

This level of transparency ensures engineers can track performance, confirm settings, and diagnose issues quickly whether on site or connected remotely.

Web-Based Control Panel

The AAREFF remote interface allows engineers to configure transmitter and RDS settings directly from any browser, providing complete flexibility and instant control.

• Frequency & Power – set operating frequency and adjust RF output remotely
• DDS Calibration – fine-tune digital synthesis for precise operation
• RDS Text – edit scrolling station messages in real time
• Program Identification – configure PI codes and PTY types
• RDS Carrier Control – switch the 57 kHz subcarrier on or off instantly
• Service Commands – enter advanced commands for maintenance

With this secure, web-based control panel, you can manage your transmitter and RDS data from anywhere in the world.
