https://www.venus-itech.com/download/SW_3B_Troubleshooting_guide.pdf Pretty slick rig and cover 5-16Mhz shortwave. about as small as an Altoids tin. I posted this separately from the gear review as this is the tech side of the rig. I didn't download the work here as I have assigned the copyright to Venus Technology. However, the download in unrestricted, should you wish to have a copy. have fun
