Back in the mid/late 1990s, I was that guy who loved his 9800XL Ultra Classic phone. Best RF of any (then current) handheld cellphone (remember when people actually TALKED on phones and not just stared at them while ignoring their friends/family?).
I wanted a PFD3000 just to be that guy. My old radio system supported full duplex interconnect. Heck, we were paying AT&T for three PLIB lines until 2016! I remember making a full duplex call on our old system back in 2000. Would have been the cat's shit to have a PFD3K back then.

Freakin' awesome! There was a transportation company in Seattle using full duplex PP radios, I believe.

I've got some oddball Uniden and EF Johnson duplex portables I'll post up later.

Speaking of oddball duplex SMR radios, I present the EF Johnson Viking CX and Uniden SPS8000ED.

They're big pics, so click away!

What's the deal with the Uniden unit? Never seen one before. I threw it in to Google and all I got were Russian sites...

That looks a lot like one of those Qualcomm PCS phones that were private labeled.

I was told both the Uniden and EF Johnson were 800mhz full duplex LTR radios. I've got a manual for the EF Johnson and *might* have a user guide for the Uniden. I'll look in some boxes.

I've also got an Ericsson IPE200 which was also an 800mhz full duplex EDACS radio / phone. There was another one known as the Allegra: http://www.repeater-builder.com/ge/lbi-library/lbi-39110a.pdf

Okay, found the owners manual, original packaging and a second NIB unit! Apparently it's a full duplex 800mhz radio which operates on LTR or ESAS trunking. Can also do regular PTT conversations and half-duplex interconnect.

More on ESAS trunking: https://urgentcomm.com/2002/09/01/poor-mans-multisite-trunking/

Also a couple images of the IPE200 duplex EDACS radiophone. It's a solid block of aluminum and a fraction of the size of the L3000 / Lingo handset. This makes me want to try and track down as many SMR "phones" as I can. This has certainly piqued my interest.
