So, being that this is my mobile and permanently mounted in my truck, using the SCU20 cable is not a valid solution. Thus, I am left to the SC card method, which is okay. However, the Yaesu-supplied software is questionable- for starters, it doesn't even accept the data from the radio itself. I backed up the radio to the SD card, brought it in and put it in the computer, and when trying to import the SD card data into the Yaesu ADMS-7 software, it gives an error reading the .dat file from the radio. Now, I do recall reading somewhere that the RT Systems software, while being a paid-for product, is superior to the Yaesu program, if only marginally so. My question is, is it worth the 25 bucks? As it is now, I am looking at sitting in my truck and manually entering frequencies and offsets and CTCSS/DTMF. And for the head pounding on the desk I have been doing with the Yaesu software, I am all for it at this point since it doesn't appear that chirp will be supporting this radio anytime soon. So, 400 owners, what's your take?
