The Tokyo Hy-Power HL-1.2KFX works perfectly in all bands with full RF output, except 40 meters.
In 40 meters, the amplifier works as like if it was on standby mode, there is only RF from the driver at the output with no amplification, there are no warnings nor indicators and SWR in that band is around 1.3
Any guidance or input is appreciated.
