Can a B2 Spectra be upgraded?

[hoser]

Used as an RF MODEM, this 900MHz Spectra (with no buttons other than volume and mode rockers) has a MAX MODES of 4

Can I upgrade this unit for more modes, convert it to a C2 or C7 perhaps?

MLM is v5.10
EE = 114

Can I swap the MLM or try BIT BANGIN?

What's the model/ID#?

I bit banged the snot out of several of those lately. Not feature rich but will do 10 conv modes and 100 trk modes post bang.
