SOLD! B Grade RM KL703 HF 25 - 30 MHz Linear Amplifier

The KL703 is a new 500W linear Amplifer for use between 25 and 30 MHz, (developed for the 10m amateur radio band).

It can be used for all types of narrow band modulation (SSB, CW, AM, FM and Data). It is particularly suitable for portable / in-car operation, as it requires a supply voltage of 13.8 V DC.

The KL703 requires approximately 30 W for maximum output power. The harmonic output is better than -55 dB.

The KL703 also has a RX preamplifier that can be used to increase the readability of weak signals.
