Reminiscing about my first (and favorite) HT, I did a search for TRC-214 (did it last week too, found nothing). To my surprise, radioshack.com came up (website heading says "Radio Shack Is Back") and to my even bigger surprise, the page I was brought to was talking about the radios from the 80's and had a GIF of the 214 manual scrolling which included the schematic. And that's a schematic cbtricks never had, so add it to your collections!
