Not if the dynamic range of the analog electronics limits it, which is what Joe has pointed out. Often those extra bits are "advertising bits" -- they fool those who don't know any better into believing that more bits is better. Actually, it's far more important to optimize the signal level that the A/D converter sees. That's why I like the Tascam USB interface better than the Numark -- it has a much greater range of gain adjustment and a clip light on the front panel. That allows me to easily optimize the 90 dB or so of dynamic range that its 16 bits provides. Besides -- the 90 dB dynamic range provided by a decent 16-bit A/D is probably more than most hams will ever see at the audio output of their radios. While the radio itself has much greater dynamic range, the WORKING dynamic range is limited by noise received by the antenna that is often 30-50 dB greater than the electrical noise levels inside the radio. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
