FWIW, Drew and I ran two DJ-G7's in full duplex mode into a comms tests set, one was Drew's very early model and mine was a more recent model. We also took the opportunity to test a TH-D7.
We ran the tests using AO-51's uplink and downlink frequencies. Drew has the actual figures, but as I remember it they were like this:
Early DJ-G7 15dB desense Later DJ-G7 5dB desense TH-D7 1dB desense
The test involved adjusting receive signal power until we had a 12dB SINAD measurement, first without transmitting then while holding the radio's PTT.

Hi,
Sometime back, while my rig was on back order, I asked if anyone had used Icom programming cables with it. My rig finally arrived, as did shortly thereafter new firmware and most recently a memory cloning program. With that, I have been able to test both the Icom OPC-478 and the RT Systems CT-29A cables. (Both need a stereo 3.5 mm to 2.5 mm adapter, plus the EDS-10 adapter which breaks out the Alinco connector to separate microphone and earphone connectors.) In both cases, I have found that they work perfectly for both memory management and firmware upgrade. If you already have a similar cable, you can probably get by with a $4 adapter from RS rather than a new $55 cable.
Unfortunately, the DJ-G7T is not so far proving to be an adequate satellite rig, but that is another issue.
