In general, the TH-D7A/E can be modified to all configurations.... But
the hardware is different between D7E and D7A because the UHF SAW
filter frequency is different and the narrow deviation filter are
different.
The D7A uses a 438-450 SAW filter for UHF and wide band LC filter
for 400-438 and 450-480MHz.
The D7E uses a 430-440 SAW filter for UHF and wide band LC filter
for 400-430 and 440-480MHz.
