[Elecraft] Tinnitus and the K3 RX EQ and Related Variables

[Randy Moore]

Costco does have different brands, but I've gone with their in-house
Kirkland brand. These are rebranded versions of another manufacturer, and
that has changed from time to time. One can discover the actual maker with
Google, or just ask the Costco hearing aid people.
