RM KL 503 HD
RM KL 503 HD
The RM KL503 HD (High Drive) Version 2021,
Mosfet linear amplifier with a frequency range of 25 - 30 MHz.
The RM KL-503 HD has an output power of 300 watts AM FM and up to 450 SSB and can be driven in from 1 to 35 watts.
This amplifier (heater) especially helps you to transmit further with for example your Lincoln sending in at full power.
But also helps you receive better by no less than 26 dB pre-amplifier.
When turned off, you can continue transmitting up to 50 watts.
