Adjust R Tor Best Waveshape

Fig. 89, A pulse generator is needed to adjust noise limiters for best results. Many hams who operate mobile have had the embarassing experience of running their battery down by talking a bit too long. One way to avoid this is to use two batteries, one for the ham gear and one for normal car needs. However, some way must be found to keep them both charged, yet make sure that the ham battery does not steal energy from the normal battery. Schemes to accomplish this used to be complex, with heavy...
