Description
KL-703: Is a new 500W Linear Amplifier for operation between 25 and 30 MHz, (developed for the 10m amateur radio band). It may be used for all narrow band modulation types, (SSB,CW,AM,FM and data modes). It is particularly suitable for mobile operation as it requires a 13.8Vdc supply voltage. The KL-703 requires about 30W for maximum output power. Harmonic output is better than -55dBc. The KL703 also features an RX pre-amplifier that may be used to increases readability of weak signals..
