Demo of a National LF-10 LF/VLF Preselector Being Used With an HRO-500

I have just completed work on a National HRO-500 and matching LF-10 LF/VLF preselector unit. This video provided a brief demonstration of how this combination is used. The LF-10 brings the spec. of the HRO-500 on the 5KHz to 500KHz tuning range on par with its MF and HF spec.

I do too - no bits and bytes in this setup! The receive weighs-in at 32lbs and the LF-10 around 20lbs
