I’ve been trying to send out some test calls on the MF/HF and not been having much success with receiving responses, the equipment is working correctly.

Radio in simplex or duplex mode? A3E or J3E (i.e. USB) or another? Use J3E.
As for frequency, the 8MHz range should work most often. Check pub117’s frequency selection guide.
