I went into the boards and reset the jumpers 180 degrees. Checked the connections and powered up. Keyed the mic and T appeared on the screen! Checked SWR and sent code using another radio to listen for the signal. It transmitted without any problems. Life is good! I like this small radio out in the field. cheers, 73

Have a X1M which has been upgraded to Pro. Had not been used for over a year and now is not transmitting. Various post indicate a transistor failure. I am not able to do the repairs, is there anyone who could do the repair? I am in Goleta, California. Thanks It's weird being the same age as old people Gato Viejo, raton tierno KI6DOZ

Hi all, I have an original x1m that was upgraded to a pro. However, now it doesn't come on. I thought it was because I had a bad new pro faceplate but looking back at my notes it looks like I did get the radio to boot up with a new pro face plate. I checked briefly too and it doesnt appear to come up via CAT either. When i turn the power knob I hear the click of the power supply come on but nothing. Any ideas on where to start focusing my attention to look at? Thanks

Hello everyone, I recently purchased an X1M but it did not come with the USB cable. What cable is suitable for this? Can I use a g90 cable and replace the 3.5 mm plug with a DB9 connector or is there something better? Does it use 3.3 or 5 volt signaling? Thanks, randy.ab9go@...

Hi, I don't have an X1M, but I have just got the XPA20 which I think was designed to go with it. Has anyone here owned or used this amplifier? It powers up, and I can flick through the menues - I have downloaded the user guide. What I don't know, is what it requires on the "PTT" jack to switch from rx to tx. It appears to be a four wire 3.5mm jack socket. I'm guessing that it will just require a grounding on one of the connections, but it would be good to know before I brick it! Can anyone help me, please? (I am hoping to use it with other QRP radios) Many thanks, Adrian

Hi group, I need help because I was updating 1.07 and the radio stopped working and I'm trying to update it and I can't. Maybe someone has a batch for this radio version 1.6

Hi, since years I did not use the X1M. Now back in HB9 - checked all. Firmware is X1MPRO V1.024 USA from March 3.2014 Is there a newer one eg. on Github or elsewhere ? Makes 80/40/15m 6 Watts - 30/2017/12m 5 Watts, 10m 2 Watts - this is in the usual Range for X1m? Its possible to copy from a Memo Channel to VFO ? TNX Erich

I have an X1M that came with the OLED Pro display. The display recently started to have a minor but annoying issue. The "F1" button which controls "tuning speed" and the "F2" button which controls "mode" seem to have linked in some manner. When I press the "F1" button to cursor from khz to 10khz to 100khz..etc moves the cursor but it also changes the mode (LSB, USB,CW). Example- If my frequency is set at 14.250.000 USB and the frequency display cursor has the "0" to the left of the decimal point underlined, the cursor will move to the left under the "5" but it will change my mode from USB to either LSB or CW. I removed the OLED "pro" display and put the original green LCD display in its place and the radio and display control work as they should. If anyone has an X1M Pro that is a basket case or a working Pro display, I would be interested in replacing my display.

Hello, from one day to an other the x1m lost nf Power. I have no complete circuit and servicemanual for messure and no oszi. my Know-how is also Not very high. Tx, Display is fine. At Power On the „palim“ also not to hear. speaker and Headphonejack are checked. What i hear was a quiet Power on „palim“ on the cw Tone poti. I put a mic ampliphier on this btw. The cw-side tone is also not to hear in cw-tx mode. could anybody help me what i can check and give me some meassuring points with voltage Ort so. At the moment i have only a normal multimeter I warnt to give the sound back to this fine little transceiver. my supposition is a failure in nf amp. like lm 386 dead or faulty voltage. Thank you very much for Reading and any help or even a solution 73 Ralf

Aloha! I have a x1m pro. It came to me in non-working condition. I really appreciate the files. Thanks! I see not much activity here. So, signed up for email updates. Will post some story if I get it working. 73, -bob ah7i

Hi group, I bought a used x1m pro two days ago. It works great on 80 and 40 meters bands ( full 5 watt output and good reports), but on 20 , 15 and 10 meters bands it uses just 0.2A and virtually no output (seen on my wattmeter). I noticed that when I transmit (with a dummy load) outside the ham bands I get full output power also near the ham bands ( E.G 14.400 mhz), so I think that the problem is somewhere in the band pass filters. I desoldered the two relay switches of the 20 meters band filter and they worked fine, also tested all the other relays and toroids and everything seems ok. Any ideas? Has anyone had the same problem? Thank you :)

I have slowly made progress with the X1M. Now I have narrowed down a SSB issue to the microphone. Having read the instructions on one of the online configuration PDFs I would like to know if there is a way to calibrate without any meter or additional hardware. All I have is the X1m and a SW receiver which can be used to pick up a transmission. Currently the SSB transmissions are extremely garbled and muffled, but they are on the correct frequency. thanks,

I recently picked up a x1m Pro in working order. It seems to function as it should. It currently has v. 1.023, 1/21/2014. First my electronic skills are marginal; I can solder two pieces of wire together and they will look like crap, joined but ugly. I try not to do any modifications because I will eventually create a non-working item. I am finding the CW sidetone extremely loud; using a straight key. I adjusted the trim pot 90 degrees to the right (as shown in the documentation), still too loud. Adjusted once again 90 degrees to the right and still too loud. If I bottom out the trim and back off 90 degrees from the bottom will this help lower the volume and not create a new problem? I see there are several updated firmwares. Must they be installed in order or can I load the newest? Where can I find the upgrade procedure for updating the firmware? Suggestions are welcomed. T

Hi, Bob! I posted my archive on x1m when this group moved, dunno if it is accesible via group, uploaded them here, https://fex.net/s/cxkef6l . They will be accessible for a couple of days. Google doesn't like this archive as attachment, possibly because of executables of firmware upgrades... This is all I have on this TRX, hope you will find files you need. WBR, Yuri UT4ULU

Hi everyone, knowing now that the yahoo X1M group no longer exists, the is my last resort. I bough the X1M back I'm 2014, I guess, due to busy life I only realised that my X1M was defective now in 2020. I'll explain what's going on. I get full power 6 watts out of the X1M when the BPFs for 10 15 20 40 80 bands are not engaged. out of the ham bands the radio is not designed, it works really well, very sensitive receiver and again 6 watts. I suspected the BPFs or one of them could be faulty, so I decided to bypass the BPFs. Things got worse, therefore I can assume it's not the BPF. I've checked the the RX/TX relay and it's fine too. I'm running out of ideas here. Does anyone know what's going on with my X1m? Thank you in advance Flavio VE2ZFP
