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

* Headphone output Impedance: 4 to 8 Ω (will not drive an external passive speaker)




X5105 Transmitter Specifications




* Output Power: 5 Watt SSB, 1.5 Watt AM Carrier @ 13.8 V DC
* SSB Modulation Type: Balanced modulation
* AM Modulation Type: Low level amplitude modulation
* FM Modulation Type: Variable reactance frequency modulation
* Spurious Rejection: >45 dB
* Carrier suppression: >40 dB
* Sideband Spurious Rejection: >50 dB
* SSB Frequency Response: 400 Hz-2.8 kHz (-6dB)
* FM Max Deviation: +/- 5 kHz
* External Mic Impedance: 200Ω to 10kΩ (Nominal 600Ω)




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
