Re: Old Radio Shack SPL cal

Just thought I'd kick out some feedback on the old RS meter cal.

I have a friend who has a 33-2050 (latest analog I believe). I ran and plotted a set of curves manually using a low freq test disc with 1/6 octave steps. I then ran my old RS meter (42-3019) and the numbers were generally the same. A few steps did show some differences but it was always less than 1 dba. It would appear by this analysis that the curve for the 33-2050 will work just fine for the older 42-3019 meter.
