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.

The dongle I bought:

UPDATE-SEPTEMBER 2020....
This afore-mentioned dongel has dies after 2 years. I bought a new one from Banggood for about $20 which was of poor quality and noisy... useless.
Next I bought one from the RTL-STR.COM website... this one is of good quality, and works well as it should...Carl Laufer who runs the site gives user support and answers Emails. Dongels from other sources may be cheap imitations... so I advise don't waste your money on others sources.
The dongel gets quite hot, as did the previous one. I suspect that the previous one was damaged by the heat... Although Carl advises me that getting hot is normal, I attached a heat sink from the CPU of a scrapped computer to it which dissipates the heat beautifully.
