The problem here as I understand it is that full duplex and wideband receive
are not compatible. I would hazard a guess that the manufacturers see
wideband dual rx as a more marketable facility than full duplex.

One other facet is that full duplex radios have tended to be larger,
possibly due to the size of the filters, although it may be simply that
no-one's developed a new one for many years, since the days that HT's tended
to be somewhat larger.

I live in vague hope for the Yaesu VX-8 that I got my hands on at Dayton,
although this was a preproduction model and I was given a stern warning when
I contemplated punching the buttons. There was no 'DUP' key that I could see
