No, it's not an STX, i have an LPE-200 that has been sitting on my shelf for about a year, i actually got it from a yard sale in tennessee, the guy was a rail buff and he thought it was VHF and he sold it to me for $200, and i heard that you can set an EDACS system up on RX only, i heard there was a way, and i would like to utilize it, it's currently programmed to ITAC non rebanded frequencies, and i can't find anyone to program it, but i got 6 STX radios with a RIB and cable from ebay and my local radio shop will program the whole lot for $100 to RX only, but with the LPE they can't, they don't program that line of radios,
