[chirp_users] VV-898SP

I have a new Leixen VV-898SP backpack radio and it works OK with the factory software. The problem I am having is the latest version of Chirp won't allow me to input frequencies over 470 MHz. The radio transmits to 470 MHz and receives up to 520MHz. I need to use it to monitor public safety on 470-490 MHz as a receive only radio. I have no need or desire to transmit above 470 MHz. Can this be addressed somehow? Thanks Steve Black KB1CHU
