My Serial is CXG11135

Send photos. It may be fixable. I had that problem. Turned out it was a relay. Someone else had burnt diodes in the SWR protection circuit. The Mitsubishi RF Mosfets are pretty robust and will take a lot of abuse. The radio is pretty simple, analog signal path and not much more complex than...

link to the Mouser part for the RF switch chips https://au.mouser.com/ProductDetail/873-AS179-92LF I'll post the results when I get the chips in.

I have an outdoor version with blue buttons. That one That's with the older firmware loaded when I had it in bits

Back on 14 August 2020, I emailed customer at cqxiegu asking for the latest firmware for my outdoor blue button version X108G Curry sent me this file Thought i would share it here

I know its been a while, but there is a list of parts in the service manual that you can use as hints for what they're likely to be. The service manual I have doesn't show the component numbers nor values on the diagram. Later versions have different components and or completely different...

Hi All I wanted to be able to run FLDigi to decode CW while still having noise come out the speaker. On the back of the unit is an Aux cable, which is a serial connector to the CPU, but not really necessary as we already have a micro USB connector for the radio already. I fgured I could use...

Hi all I have an earlier blue button outdoor unit which has had all sorts of issues over the few years I have owned it, but I somehow manage to keep the thing going. Specifically the problem I had recently is the recovery time from TX to RX when the unit is cold. The unit clicks back into...

sounds like a flat CMOS battery. There is a small button battery I had to replace in mine. Works fine now

I mostly use the rig for CW. While the CW filter drops the S meter reading significantly, the signal to noise ratio improves significantly. I tend to give RST reports relative to the base noise, rather than rely on the meter. I have a Yaesu FT747GX and that knocks an S point off the signal, but...

This was the item I purchased and it worked perfectly. The radio is still marginally OKishh, but at least I can read the screen again https://www.aliexpress.com/item/32259768807.html was the part I purchased with the short lead. Pretty straight forward to change

Have a look around in the "Files and mods" thread for the latest version. I had a look and I have two files X108G_OLED_FW_V2.00.1_build006(26M).xgf dated 8/5/17 and X108G_OLED_FW_V2.00.1_build002.xgf dated 24/12/16 Not too sure which one I am running but I do havea 2017 software versio date...

Just confirming that the silver conductive paint is working for the time being

I had issues when connected to a linux box. Same issue. I connected up an old Windows XP notbook and it all worked OK. I havent tried any other devices, but I have read that the USB interface can be a bit fiddly.

OK I am u and running now The schematic on line is different to the version I have for the input stage on the RF power amp. The long IPX jumper feeds the modulated RF signal to the board. Its pretty low level. Maybe 50mW. You can see a test point next to the jack you can connect a CRO up to. I...

Removing the resistor opens up the transmit from 100KHz to 30.000 MHz I get between 15W and 22W across the spectrum. It wont fix your transmit problem. I'll post my fixes for you on the other thread

Hey Bob I was given one which is no longer transmitting. I have a serial beginning with an 11. slightly diferent scematic. There is no transmit to speak of. Maybe 10mW. I have reseated the ribbon cables, replaced the battery (socketed same as yours) and flashed the 7 May 2017 firmware. I have...

I've used some silver paint on the pads of the ones that dont work and that seems to have sorted them out. They are usable now, and while I can not comment as to how long they will last, the silver seems to stuck to the pads well enough not to scrach off with my nail

I'll admit I didnt, however I expect that these have just factory defaulted anyway as the CMOS backup battery was flat. I have replaced it and it now remembers settings. AFAIK they are required to align the radio in relation to the filters and such, rather than the old trimmer to tweak the...

Quick update. Reseating the ribbon cable between the RF board and the top board has fixed the Keying problem, however I still have no power to speak of
