BI7CZF CZF??? Are you really CZF?? Where is your QTH? I am CZE, we should use the same callsign, and we were both part of the group that took the exam in Hengyang. I have successfully connected with 439.680 MHz, and the repeater is located near Chengbu Iron Dingyan. Last night, I connected with BI7IZM, and yesterday afternoon, I connected with BI7CZI. CZI also went to the repeater location yesterday, so it was lucky for me to connect.
