I'm using Mark's NQSMHS board with a TM-D700A. Works very well. Here are the D700A settings I'm using, which were passed onto me from Fred PA4YBR:
Settings in firmware: TX Invert = OFF, RX Invert = OFF Settings in radio: MENU 1-9-6 (Radio -> AUX -> Data Speed) : 9600bps (default 1200) MENU 1-3-6 (Radio -> TX/RX -> Wide/Narrow) : NARROW (default WIDE) [TM-D700E only] Ignore anything about data modes or such.. that all uses the internal FSK TNC (1200/9600) which is irrelevant here. I'm sure you are using the same settings, and you've done the obvious and adjusted the TX trimpot. I'm curious where the antenna for your D710A is located relative to your IC-80 antenna. If your D710A antenna is outside, try going outside and see if the R2D2 is still there. Sometimes the various wires in the house can result in multipath, and gmsk is very vulnerable to multipath. On the D700A, I ended up placing a switch between my outside antenna and a small indoor antenna. When indoors, I use that, and no more R2D2. Wish I could be of more help.

I got my NQSMHS build over the weekend and tried getting things running today but cannot get rid of the R2D2 on Echotest. I've been the full range of adjustment on the data terminal input and output levels via the MCP-2A software and have carefully adjusted the RX and TX pots at each setting, but still get far too much R2D2. RF Read is fine. The NQSMHS is interfaced to the rigs data terminal (9600 baud input) and the rig is running NFM mode on 2 meters. I'm transmitting to it with an IC-80. Any thoughts? On a related note, I tried running the DVAR Hot Spot software to see if I could listen to some traffic and adjust things further, but the software says the GMSK modem is disabled? Didn't get a chance to troubleshoot that much, but thought I'd toss it out there with my other problem. 73, Mike WM4B
