Ive tuned up a bunch of radios in the past so i know enough to get myself in trouble. Hi. But... This signal to noise ratio i just cant seem to get. When tuning the rx i use an old volt meter from the 70's and plug it into the external speaker. When tuning i keep turning (the correct pots) and watch the meter climb. I know im done when the meter stops climbing. What is a better way of doing this? What piece of equipment should i be looking to buy to get the noise to signal ratio better? Thanks for the help or recommondations. Jerry... BTW, i do use a signal generator to inject the signal..
