my buddy rick had a 690 (450 with 6m). digital s meter with mod scale works on recieve, very nice radio. he liked his very much but sold it as he never had a ticket, he would just listen and money talked. the fan liked to come on even when the radio was barely warm. he ended up changing it so it would come on later, pretty annoying as he would turn it on and 10 seconds later the fan would spin.
if you are going to be using this on 11 meter in town i would look at a different radio.his was getting hammered pretty hard as the agc was slow to react and you would nearly always have to have the 20db pad on and it killed most far signals. very clean audio, powerfull (40 watts am and just over 100 ssb) ran no problems on a mfj 35 amp power supply. it was unbelieveable as far as ssb goes and had solid am sound. very clean. it was not as loud as most of the current radio's go but it was clean.
all in all if you can score it for a good deal than do it make shure it has an auto tuner. its much cheaper to get one with it installed rather than buy one from ebay. if you dont plan on using it take it out and sell it, should see $80 or better. otherwise take a look at a kenwood ts 570d. might be a little cheaper to go that route and you pick up some more options like dsp.
