Hello,
In my 1MHz-30MHz receiver, **broken link removed** I am trying to achieve more amplification with simple devices (not MMIC) out of the RF preamplifier BC109C, without changing the 4.7pF capacitor.
I consider a darlington transistor (BC517) instead of the BC549c. Keep in mind that everything has to be kept simple, it is a hobbyist circuit.
Will I see any gain improvement up to 30MHz compared to the BC549C, or it does not worth the effort?
