Crystal filter alignment

WebThe normal filter is easy, just align the IF to the crystal frequency. This may not be exactly the published frequency, however, this is the practical frequency to use, and it should not be far off. If the crystal doesn t work, dismantle it and clean with alcohol, or get another one. A sweep generator is also helpful here. Webhave a very wide sweep band (since a TV IF is 4.5 to 6 Mhz wide), and are usually swept at a 60 hz rate. For typical receiver IF alignment, we’d like a sweep bandwidth of around 5 …
