Technical description CS-818

The CS-818 has a tuning range of 1.8 - 54 MHz, with input powers from 0.5 - 30 watts. Thus, it is ideally suited for QRP transceivers like the Yaesu FT-817 or FT-818.


The easy-to-read 1.3" OLED display provides information about the supplied transmit power and the current SWR value. 


The included battery allows up to 50 hours of operation. Relays with latching allow power-saving operation even when the tuner has been switched off.

Of course, the CS-818 can also be powered and charged externally. Both a 13.8 V DC-in socket and a USB-C port are available for this.

Application description CS-818

The device's firmware can be updated, and future updates can be performed by the user.


With its compact size and long battery runtimes, the CS-818 is perfect for QRP and portable use. Antennas with 5 - 500 ohms can be tuned.


If the tuner is operated with the Yaesu FT-817/-818, 20000 memory locations are available, whereby known frequencies can be tuned quickly when recalled. For use with other transceivers, there are 10 memory locations.


Marco, DD6FM, provides helpful tips about operation and configuration of the tuner in a test report.
