Actually, it's both.  There is very noticeable desense, and the sub-band VFO
is less sensitive than the main band.  The main band is for ham bands only,
where the sub-band VFO has the wide-band receiver.

You *may* be able to work with the DJ-G7 using memory channels in the main
band, but won't have full-duplex operation that way.  I have not tried it using
memory channels for the satellites.

The CQ magazine review was also a huge disservice.  The DJ-G7, although
a good radio for non-satellite work and with analog FM at 1.2 GHz (the main
reason I kept one of the two I bought at Dayton in 2009), is a disappointment
for satellite work.  Go with your FT-530 for satellites.
