LogHX3 has a critical bug - in ADIF import the call and name are written twice - instead RX4HX is in the log RX4HXRX4HX (see attached screenshots).
Otherwise is your program very nice and is a candidate to my favorite. This bug appeared on latest builds 686 and 688 running in Windows 10. Your program also needs to be run with root privileges or with security level turned to the lower value.
