Is it just de-sense, or lower sensitivity on the sub-band? I have one on loan I am going to try (A-B compare to my FT-530 with the Arrow), as soon as I find a SMA-BNC adapter in my shack.
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.
I read the QST review and the author said "no issue" except for same-band sub-band, but he is not an experienced LEO user (as he stated in the review).
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.
