LF: Re: LF performance FT-847

Hello Uwe,

Use a 30 - 40 dB tuneable pre-amp.
I have attached a circuit diagram.
The beauty of LF is that good selectivity can be achieved in front of the 
active devices, which greatly helps to reduce overload problems.
At HF it is often common sense to use as little gain as possible in the 
front end of a receiver.
At LF I have used up to 50 dB gain without adverse effects. I found that 
these high gain tuneable pre-amplifiers opened the band for weak signals 
here.
Best regards,
