CHIRP

Hi all. I am looking for help when it comes to CHIRP and the Icom IC-T70 radio. I have tried 2 identical cables form Valley Enteprises to communicate with my radio.
Driver is correct as is the COM port setting. All I ever get is "failed to communicate with radio; unexpected response from radio"
I'm running Windows 10.
I see there are already some similar bugs being reported.
I have another cable from Valley and it works great with my Yaesu 817-ND.
Been at this for about three weeks now back and forth with Valley and Icom and they can't help.
Any assistance may keep me from trading this HT in on a half dozen Baofengs!!
Thanks for any help.

Regards, Adam
