Xiegu X5105 XCVR questions, auto memory keyer function not working and intermittent PTT

Lou N2JPR All Messages By This Member #948 开云体育 I just found this group and have some questions about my X5105. ? I got my unit via MFJ in late 2020 and have made 430 CW QSOs with it. It is a FW V3.0 unit. I have the following issues, to date. Issues: ? Auto memory Keyer: I have followed the below instructions exactly, numerous times and the internal keyer never transmits. I can, however, decode CW via the CWDEM mode nicely. Here are the instructions to load and send: ? To configure the 10 CW memory messages: Go to Menu 3 by pressing the MENU button until 3 appears beneath the power meter on the display. Hit MSG Select MSG number with VFO (Tuning Knob) Press the EDIT button Scroll through letters / numbers with the VFO and hit INS for each selection When letter/number selections are complete,? press SAVE Repeat for each custom message and when done, hit QUIT ? To play the 10 CW preset messages: Go to Menu 5 by pressing the MENU button until 5 appears beneath the power meter on the display. Select DIGI Select CWDEM from mode choices (leftmost button in menu 5) by pressing the button until CWDEM appears Repeatedly hit MSG to select specific message number Press PTT on body of rig or perhaps press PTT on mic. This will send the selected message one time. To exit, hit MENU for other menu selections ? In CW mode, the PTT function does not always trigger whether I use the: PTT button on the radio. PTT button on the mic. External PTT input signal via the Accessory jack. Whether I have the PTT software setting to Normal or Toggle. I noticed that the intermittency it is associated with the battery charging function. These are the behaviors: The PTT will always trigger properly if I have no DC Charger plugged into the External Power jack. The PTT will intermittently trigger if a DC Charger is plugged in and the charge voltage is below 13VDC. The PTT will trigger almost never if a DC Charger is plugged in and the charge voltage is above 13VDC. With these symptoms/conditions, I am wondering if I have a ground differential issue? I use a 12VDC car battery to power the transceiver and other accessories, a separate Li-Ion battery pack for the keyer, and a separate NiCAD battery pack for the external audio filter/amplifier. I could use a single supply for everything but the wiring changes in my shack are not easy. ? Has anyone seen these anomalies and can offer any suggestions? ? Best 73, Lou N2JPR ? ?

Lou N2JPR All Messages By This Member #1261 开云体育 Hi X5105 Group, This is a follow up post to my previous post (1/10/2023) on my X5105 that had intermittent transmit/PTT. After months of trial and error with no clear indication of a physical (Antenna, Power, Relay, Connectors, etc.) or settings cause, the rig eventually went to 100% of the time with no-output. Phone calls to MFJ and Radioddity were the same recommendation which was that it is a firmware issue requiring a re-flash. Radioddity strongly recommended that they could send the rig back to China for a full diagnostic check and repair. ? An online search of this X5105 issue showed that I am only 1 of many having this issue. Most Hams cut their losses and sold the rigs. Those opting for re-flashing had mixed results; everything from a fixed radio with feature and setting changes to not working at all. ? I then went down the road of researching an upgrade. The X6100 and X6200 are hot items right now. However, there are several YouTube videos showing that these rigs are not-yet ready for prime time with many software issues encountered and documented. Of special concern to me, there are a few specific mentions that “the X5105 no power output issue has been grandfathered to the X6100”….ouch! ? So, I attended a Hamfest last week and put my originally purchased new 2020 X5105 ($499 from MFJ) on my table, mint condition, all accessories. I let it go for $200 and cut my losses. ? I am a 45-year Electrical Engineer with a focus on analog and digital communications. At this point in my life, just engaging retirement, I am not looking to grow my work bench with projects, especially lethal-outcome flashing projects on SDRs that could render a brick. I want to maximize operating on the air, exclusively CW. ? For what it is worth, I am not impressed, charmed, or fascinated with any SDR. This Xiegu was absolutely the worst-fear outcome I have been trying to avoid in this venture. Where an expensive radio simply stops transmitting due to a software bug is in my top 2% category for a worst case. Who would purchase a rig knowing they will be at the mercy of “code” for a catastrophic failure? Not me. ? At this point, in the category of pursuing knowledge and experience in this Amateur Radio niche of SDRs, I would consider a rig for <$100. I have found a USDx QRP XCVR clone that is of interest. I may pursue this open-source code software rig for the $81.70 price + $3 shipping. I can cut my losses again for <$100, if necessary. But nothing more from Xiegu until they get their act together. ? I would appreciate any input/feedback on this post with shared experiences and recommendations. ?

JP McGinley All Messages By This Member #1262 Lou, ? I had two of the 5105s that did that. The fix action is to disassemble the radio, BE CAREFUL of the side panel prop leg springs. They will fly out.? ? The radio has three or four boards and use brass standoffs to provide grounding to the boards. Over time, the screws and standoffs loosen and causes the very low milliwatts to zero output.? ? I took mine apart and cleaned the standoffs and ground plane they touch. Then using needle nose pliers to hold the stand-off, used a JIS screwdriver to tighten the screws. Never had any issues after that.? ? I bought and quickly returned the Xiegu 6200. Firmware issues and output problems…”only in certain serial numbers”, ya right!! ? The 5105 is a nice radio, quite portable and as you know, will tune just about any antenna.? ?JP KA3BWP
Lou N2JPR All Messages By This Member #1263 开云体育 Hi JP, Thanks for your response. Yes, I did the standoff tightening about a year ago. It did help the output power increase, but the intermittent output down to 0W continued. As the problem got worse with increased key down time with no power out, and continuing to hear the relay click on and off, it made me suspicious that it was software related and, Radioddity confirmed that. Apparently they have had a rash of these failures.
