I just recieved one via mail today and boy what a neet little radio it is/ I am going to put that in place of my little Uniden PC122 I have in are spare car. I made a few 10 meter contacts on the 257 tinight and audio reports were great with the stock mic. I got a handheld D104 M6B with the radio aswell and Im going to keep the original mic on it seeings how I have it set where nobody new I was running a stock mic until I told them. I thought hell thats pretty good. I have the older style 257 but all the same it sure is a solid little unit tracks good on SSB and as I said it has great audio I just found the adjustment I needed for setting it to my likings and no problems. I thought the knobs were a tad chinsey but hell for what these radios cost who is gonna complain abot knobs or sweat any of the small stuff for that matter. These have plenty of cooling as far as heatsink aswell . All in all if you or anyone is looking at these for a purchase I wouldnt hesitate I gave it
