Request preparation
What would you like?
Yes — the RF2K-S supports TCI (Transceiver Control Interface) natively over LAN/Wi-Fi. It was actually one of the first amateur radio amplifiers to implement TCI directly.
The RF2K-S can use TCI for:
Frequency tracking
Band switching
Operating state synchronization
Integration with SDR software such as ExpertSDR / SunSDR
Network-based amplifier control without traditional CAT cabling
The amplifier acts as a TCI client and connects to the TCI server running on the SDR/control software.
Basic setup on the RF2K-S:
Connect the amp and SDR PC to the same network
On the amplifier:
Interfaces → General → TCI
Enter:
Host = IP address of the PC running the SDR software
Port = TCI port (commonly 40001 for ExpertSDR)
Save settings
When configured correctly, the amp follows frequency and band changes instantly over TCP/IP.
One important detail:
The “Host” field should usually be the computer running the SDR software — not necessarily the radio itself. This trips up a lot of people initially.
The RF2K-S also supports:
CAT over USB
UDP frequency data
TCI over IP
Remote LAN/Wi-Fi operation
If you want, I can also help with:
FlexRadio + RF2K-S TCI setup
SunSDR configuration
Thetis / ANAN integration
Node-RED control
Automatic antenna switching over TCI
PTT handling over network vs hardline PTT
Remote station configuration over VPN/LAN
