RM Italy KL-805V PLUS HP Black HF Super High Power 600W




KL-805 PLUS: A new SUPER high-powered linear amplifier ideal for any (24V) vehicle. The RM KL-805 ‘black line’ is a 24 Vdc narrow band HF linear amplifier covering 25-30 MHz. Maximum output is 600 Watts from 15 Watts input power. It may be used in AM, SSB, CW and FM modes of transmission.
The RM KL-805 features an independent receive pre-amplifier that provides about 26 dB gain for the received signal. Another feature is an internal RF switch so when the linear amplifier is switched on, it will automatically switch to TX and amplify the output of the transceiver when there is RF on the RTX input connector. It also features internal automatic VSWR protection and will shut down if the antenna VSWR increase about 2.5:1 protecting the transistors from damage. It is also protected against accidental DC input reverse polarity.

NOTE: Protection circuits are not 100% guaranteed. To prevent damage to your amplifier always check your (VSWR) after changing bands, no hot switching, no excessive input power etc.

NOTE: The MRF-422 is capable of delivering a maximum power of 150W SSB. Since the KL-805V PLUS is assembled with 4 power amplifiers, its maximum output power is 600W SSB FM. We therefore invite you not to take into consideration false technical indications present on the web (videos and written reviews), in which output power values ​​of up to 1000W are declared. Using a driving power and a supply voltage higher than those indicated in the table leads to certain damage to the amplifiers.
