Heil Ham Radio: Parametric Receive Audio System Demo

Jerry Lynch, Sales Manager and Product Specialist at Heil Ham Radio demonstrates the Parametric Receive Audio System (PRAS) for Amateur Radio. The PRAS and HPS Powered Speaker (HPS-5) have been designed to improve and clean up receive audio for Ham Radio. This device can help to dig out low-quality signals. It can also aid hams that are suffering from hearing loss by allowing them to adjust vocal range frequencies.

Excellent demo, you put into 2 minutes what the guy at Ham Radio 2.0 takes 20 mnutes to do, well done.

Do they all come with a high pitch wine and no RFI protection? Or is it just the one I bought?

Lovely unit, takes out all the backgroung noise. One question can you connect two radio's at once in differant inputs (assuming you dont use both at the same time).

Will this work soothing voices that sound to harsh, on some repeaters voices are very scratchy harsh not clear, and hurts my ears . Especially on 2 meter.

Will this work the same using headphones plug in to PRAS? If so which headphones are recommended? Thank you.

It has a huge flaw. The increased sensitivity and amps pick up transmissions from your rig and cause rfi problems at the shack.

Has the issue with RF feedback been resolved?
