Re: BJ stability


Honestly a varactor does not seem to be a huge impact on regen stability,  as these things can receive with high fidelity.  the varactor Q will vary some with bias but I am doubting any noticeable impact. 

My homebrew WBR has commercial varactors, and seems sharper than these receivers with makeshift varactors, but its only a coarse observation.

Has anyone measured their regens with a audio FFT like spectrogram?
