Probably the cheapest and most elegant improvement to the 706; these RTL dongles are only $10 delivered on ebay. 
How you use them is you solder the antenna lead to the IF of the 706 and use the PC to decode the IF frequency. 
This gives you the advanced capabilities of the SDR Software including multiple layers of fancy filtering.

Please note I no longer use the WIA email address where possible owing to it blocking emails from sites such as VK Logger and ARRL.
