As well as single/dual head and 1, 2 or 3 decks. It'd be expensive, but you could build a radio that would do:
Low band VHF (soon...)
VHF
UHF (380-470 or 450-520)
700-800MHz
Analog
DMR and DMR Tier 2
NXDN and Type C trunking
P25, Phase 1, Phase 2.
FPP
4000 channels per deck.
And probably more other features than you can legally shake a stick at in most states.
On the EF-Johnson model, you can do up to 4 RF decks, but they don't support NXDN or DMR.
The RF decks are supposed to be released with 100 watt models on the VHF and UHF side, soon. Right now, they are 50 watt VHF, 45watt UHF (either split), 35 watt 700-800.
The Low band deck is in response to the retirement of the TK-690, and wouldn't be surprised to see it show up in California Highway Patrol use soon.
