Re: Varactor tuned loop questions
- @ Chris,
Slightly OT, but I thought I might also try your loop amplifier in a wideband design! I'm struggling to find the MPS6521; would the BC550C be a suitable replacement?
Also, I see no value for C18 in the schematic, but two figures given for C15; I presume C18 is the 47uF and C15 100nF?
