hmm, thats the first i have heard of it, except for the few tenths between the .net and .usb.hate to tell u this, but the tl usb is not that consistant.. we had 3 at the 12" test session and lets just say 1 was not very linear throughout the frequencies and all 3 read differnetly ( about .7 db off for one and 1.3 db off from the other )
the .net i think is a bit mroe consistent
i've done the same scores from mine>5 others. in fact, in one session, i tested at a 155.0.... went to ft. wayne, did a 155.0, drove to OH and did a 155.1.
i lost .3 from my meter to the .net at a drag 3x also.
