Upgrade firmware on Quansheng UV-K5 from egzumer 0.17 to 0.20.1 and RX Oman on 10m

Just upgraded the firmware from egzumer 0.17 to egzumer 0.20.1 Here's A47RS "Royal Omani Amateur Radio Society" on 10m. One thing I have noticed is now the S meter no longer shows S5 of noise and the USB RX is clearer. The antenna is a base loaded 27MHz telescopic from Ebay about £10... I'm at ground level in Sidcup Kent SE England.
