WINRADIO WR-G305e unblocked wideband scanner receiver. This is the professional model which covers 9Khz to 1.8Ghz and it is unblocked. You can go to see all specifications and to see what is added with the professional model. Two nice additions with the professional demodulator are independent and dual sideband modes. This model in standard form sells new for $619.99 and the professional demodulator options sells for 199.99, totaling $820. Prices are from current Grove catalog. I am selling this radio for $575 including free shipping. I am selling it due to a move in to a condo and I cannot mount the proper antenna systems.
