However, the RBLHGG-5acD (Node-1) would not locate any sector modems.  I verified it was the International version and updated to lastest software and firmware.  But did notice the WiFi Interfaces reported multiple unsupported channels and the following:

Does anyone know what is causing this problem?  If so, what is the fix.

Many of Mikrotik's 802.11ac modems do not support 5 and 10 MHz channels like we use for HamWAN. It could be that this model is not capable.

You could try testing it in AP mode to see if it gives you similar errors:
/interface wireless
set wlan1 mode=ap-bridge channel-width=5mhz
print

Then to get it back into client mode:
/interface wireless
set wlan1 mode=station
