Yaesu FTdx 3000: Very, nice fully functional, Yaesu FTDX /6M Transc. This radio is very well documented on multiple places on the internet so I will not go into a long discussion of the specifications/features here. Everything is working fine and it's in good to very good cosmetic condition. The rig is not mint as there are few light scratches and rub marks on the case. This will come with the OEM Power Cord and Manual and an aftermarket custom dust cover and a quick reference mini manual as pictured. I will sell, pack, ship and insure all that you see pictured for $750 to anywhere in the CONUS. If you can pick this up in the Denver, CO Metro Area on a cash-N-Carry basis, the price would be $700. I am happy to take PayPal but will hold this in your name for one week if you would prefer to use a Postal Money Order. I have more Hi-Res Pics and can provide them upon an email request. Please respond directly via e Mail for further information Good on QRZ Thanks for looking.
