Firmware V3.0 1. Easier operation with new VOX function. 2. Fixes CW issue. 3. Properly optimized hardware greatly reduces the problem rate. ¡¡[nope, not very informative!] (I had already downloaded V3 from Radioddity, and it's V3 Build 7).? I have not updated my X5105, received in une, 2020. It's v3.0.0, according to the screen on the radio. +++++++++++++
has X5105_FW_V1_0_06_build002_beta02.zip X5105_FW_V1_0_06_build002_beta02 Update Description 1. Fixed a bug in SPLT exception in CW mode of X5105_FW_V1_0_06_build001 2. Reconfigure the audio baseband unit to enhance the sense of hearing; Also available from radioaficion is (12M)
They also have v3.0, but list no description or build number. +++++++++++++++++++++++++++++++++++++++++++++ An eHam.net (https://www.eham.net/reviews/view-product?id=13557) review from 2019-10-26 says: "the early Version 3 firmware (V3.006) has a bug in CW. With this firmware you will get a hiccup in the CW note. Dits will come out d-dit; dahs will come out d-dah. You will not notice this if you listen on another receiver near the X5105. . . . The second hardware version of this radio looks just like the A-series but it usually has the V3 firmware installed. Reports from other users on the FB group hint that some of these radios will not have the CW bug. Others will have the bug. Xiegu recently released an updated Version 3 firmware (V3.007) that appears to cure the CW bug and provide the owners of both A and B series builds with the updated screen, a much more manageable menu system and CW, RTTY and PSK decode as well as VOX. The older firmware deep menu functions have all but disappeared. Some of those settings have been moved to the standard operating screen menu. This includes RF gain. . . . My experience with this new firmware is positive. However, there are some interesting "features" involved in this new firmware. . . . While the CW operation has been improved and debugged, the new firmware allows the keyer to act as a PTT if the radio is in SSB modes. If the radio is in CW mode, the PTT button on the microphone will produce a CW note. This means the PTT button can be used as a straight key. Interesting feature. . . . The new firmware appears to make the receiver a lot more quiet but there is still an obvious white noise hiss from the receiver when the radio is not connected to an antenna. This annoyance is somewhat controlable by the RF gain setting on the front menu. (There is a deep menu function to adjust the S-meter gain to match or coincide with the RF gain control.) . . . The DSP AF filter and noise reduction filter appears to be improved. It's hard to make side-by-side comparisons when you only have one radio." --------------------- I hope all this helps those of us who are curious about the firmware variations, bugs and fixes.? I'm sure there's more out there to find, too.? Please add what you find - it will help us all.-- Doug, K8RFT
