FTS-8px Tone Encoder / Decoder

I bought the FTS-8px way over a year ago and it has worked very well on the repeaters here no differnce from the Yaesu FTS-8px I have gone and lisen to a Yaesu FTS-8 and then lisend to my FTS-8px and you can't tell the differnce. It has worked for me so well Iam going to buy anouther one just in case I ever need one in case they run out and never can find one or then I dont have to pay the high price for a Yaesu one off Ebay. Thanks for makeing them.
