New #QRP radio arrives

Posted: 02 Apr 2022 02:39 AM PDT https://va3qv.wordpress.com/2022/04/02/new-qrp-radio-arrives/



Friday morning my new radio arrived. I look forward to getting the XIEGU X5105 Portable QRP radio operating in the next couple of days. And with regards to my previous post. With 5w output the radio is a QRP Radio. and
no debate on what power did it have it set at as the best it can do its 5w (using the internal battery or a external power source)




Here is the Specs

As I sold off all my portable antennas when I sold my old FT817 will be building a couple of antennas before I get to properly test things out.




As soon I have gathered enough data to have an opinion on the radio I will share it with you
