Freq. range: 1.5 – 30 Mhz. Output power: 300 Watts
In contrast to many small amplifier for 12V operations, the BLA-300plus is an amplifier for your station desk. It covers all HF bands from 1.5 to 30MHz and all modes (SSB, CW, AM, FM) and is wel lsuited for QRP transceivers like FT-817, IC-703 etc., but also to get more power from 100W class transceivers, which can then be operated with a lower output power.
Manally switched low pass filters care for a good suppression of harmonics. Of course the amplifier does not need and heat-up time, and except for then band selection no tuning is required. The max. output power is 300W, with a max. allowed input power of 30W with the input attenuator switched on. For reception a pre-amplifier with tuneable pre-selector (10-30MHz) can be selected.
The amplifier BLA-300Plus has an ALC output and a PTT input for transceiver connection, but can also be operated by HF vox. The coaxial connectors are SO-239 sockets (PL sockets). The built-in power supply is suitable for international use with voltages from 110 to 230V AC. Multiple protection circuits support trouble free operation: automatic switch-off at too high SWR or too high temperature.
