RTL SDR dongle as a panoramic display for FT-920 transceiver de 4X1MK

This ham's use of the RTL-SDR dongle, tapping the 68.5 MHz IF of my Yaesu FT-920 transceiver, getting panoramic frequency display and frequency control from the computer. This should work with any transceiver having a first IF above 25 MHz without the need of up-converters. The dongle with a metal enclosure was bought for $20 including postage, on Ebay. There is USB-RS-232 cable between the computer and radio for computer control of the radio (which is useful with other programs for digital modes). Software used: HDSDR (the screen seen here) and Omni-Rig running in the background so the computer talks to the radio.
