There was only a spot for 1 filter but I did see somewhere, weather it was 
home made, or an inrad thing, or what I don't remember, but there was a 
board somewhere I saw that did allow for 2 filters. Stock though, the radio 
can only take 1 filter. There was the 570, 570DG, which were the 160 through 
10 models, then 570 SG, which had 6 meters in it as well, I don't know if 
there was a 570S before the G model or not with 6 in it. I got my 570DG just 
after they came out with the G upgraded models, in fact it was kind of a 
surprise when I went to place the order and found they had a G on the end of 
the model number.
