We need disconnect D2. For better description is 18mm from bottom, 25mm left, 25mm right from PCB border. I onlydisconect diode leg number 1 from PCB but we can remove it complete.7. Reassemble the radio in reverse orderIn my rig is now TX range 50MHz-260MHz, 300MHz-600MHz but only for short time about 1sec because some protection don'tenought more. Maybe TX PLL I don't know. Pernament TX range is 115-191MHz, 370-484MHz.OK. You can send me some reports or questions to email: laudis@post.sk.MODIFICATION.NET or laudis@mydeja.com.MODIFICATION.NETor via packet.73!
