Absolutely! I got my ARRL Handbook. WHat did you build? DC receivers? I've built a couple of dual conversions. Just never made a good full coverage digital synthesizer. I've made single band. I never put a transmitter on the air anymore without digital lock. But my VFOs never chirped. They may drift a little but no chirp! Drift is not tolerable for SSB reception.Not for years, and only simple ones.
I would suggest you buy the ARRL or RSGB manuals, these are essential for anything radio based - everyone here should really have one or the other (or both).
