(tr)uSDX Forum

I have found this post. But, it doesn't look like there was a working configuration.

Has anyone gotten FLDIGI or FLRIG CAT control working for the (tr)uSDX? I cannot get it to work using the settings I use for WSJT-X. I have full working CAT control, PTT, and audio working with WSJT-X though.

How did you calculate the required turns for the FT37-43 cores?

That is very similar to how my Amazon kit turned out. The black pieces on each side of the connector aren't supposed to be touching. The 3D printed case spaces out the boards to they don't accidentally touch and short.

Hello, I also ordered a kit from Amazon and found the need to remove turns from the LX2 cores. Did you have any issuees with the SWR measurement with your kits?

I had to remove one turn from all of the LX2 toroids to get the second harmonic close. Removing one turn from the LX1 toroids would increase the power for those bands, correct? Effectively yes, though what it's really doing is moving the passband of the filter around. With your kit you almost certa...

At this point I think my main boards are garbage. I tried to reflow the solder with a heat gun and now the radio menu is slower and the CW tone sounds fluttery.

I wish I knew if my boards were destined to be broken or if I destroyed them.

Does anyone know what could be causing this? It happens without an antenna, with a dummy load, and with a resonate antenna. I tested it in two different locations with the same result. It seems to happen in CW mode on all bands except for 80m. It also only seems to happen when Filter BW is less than...

Unfortunately the issue has returned and now my radio shows 13 watts out and 9.99 SWR. This happened just from taking the radio with me in the car to my university's radio shack.

The issue was my MCU had dry solder joints that weren't making contact all the way. That also was stopping me from running off of the DC jack. The jack wasn't soldered all the way on. Some QC issues with the Amazon kit.

I followed the troubleshooting done in viewtopic.php?p=1898#p1898.

But, FWD and RVS are very high voltages. Tested on 20m into dummy load.

FWD: 3.3v transmitting. 3.6v idle
RVS: 4.3v transmitting. 4.6v idle

Hello, I just build the kit purchased from Amazon. I am in the process of tuning the RF section by following the official tutorial. Although when testing the radio into a dummy load the screen shows 13 Watts and 9.99 SWR. This is on CW on 20 Meters. I have a nanoVNA like the video says and the L12 c...
