Hosp. - Dept. Biomed. Engineering Lines: 17 1). Has anyone but myself noticed the audio tone quality that commercial mobile FM gear has? Unlike your typical "police scanner" or even mass-produced FM amateur radios which have a high pitched hiss when you disable the squelch, commercial sets have a throaty sounding hiss and the voice quality is always pleasant, not buzzy. I have tried building audio filters to change the tone for my 2m gear but all I get is muffled audio. External speakers help a bit but I am convinced that they are doing something sneaky inside of the commercial stuff. 2). 6 meter questions: I am young enough to have missed the heyday of 6m popularity. Does anyone still produce it for hams? Should I build my own or modify a Motrac or something? How bad were the TVI problems from equipment used strictly car-to-car in rural areas? What kind of range advantage can I expect over 2m mobile-to-mobile? All I want are one or two freqs. Were there any "popular" ones like 146.520 simplex(2m) ? Bob Lagasse N 1 A L G Mass. Gen. Hosp.
