I just started getting into the discriminator tap/computer decoding, so I may be a bit excited about it. I have trunk tracking scanners, so I just log talkgroups, and then look for new ones to identify. It
may be a bit impractical, especially if portability is a requirement. The 246T sure seems like the cats meow if you don't need a digital radio.
The Hallicrafters name is a bit old for me. I think they went out of business before I was a speck in my mothers eye

and I couldn't even tell you what a BFO is, but the vintage gear sure looks cool to use!
