Oh man I cannot thank you enough for this... there is literally zero instructions online and have been struggling with cabling for days... Would love to see when you made CAT as well.
I fight with ft8 long time . Today is success 🎉. Now need litlle setings beaciuse sometimes RX/TX is like crazy but FT8 start working . Thank You for the plug audio/ mike description.
@@LB0FI I love QRP portable. camping and trips. I bought this radio without knowing its options. for such little money it is really great. Thank you very much. without instructions was a problem for me and many who bought them. Greetings from Poland, SQ8MFQ (now more on QRP)
I tried many times but I could not get a stable tx. I tried to make a cat cable but it didn't work. Looks like I've missed a lot of settings on this radio. Thank you for the informative video. Please go on. TA2YNN 73.
Great video Morten! I have a similar Chinese radio, the USDR+ (known as the "Red Corners") but I can't find info about the audio wiring. This one have the same connections like yours, SPK, TO-PA, UART, MIC and KEY. Do you have a guide or diagram to build the cables? Thanks in advance. Jorge VE3EAD
The closest thing to a diagram I have is what I show in the video. I have wired it the following way. The tip on the TRRS connector is wired to the tip of the TRS (Audio) and the outer ring of the TRRS connector is wired to the sleeve of the TRS connector (ground).
The connection became unstable. Somehow the whole thing was getting out of tune. So I put a 1 kohm resistor between the output from the PC and the microphone input to the trx. Now it broadcasts superbly. Noise gate 5
So I managed to break it up on vox. Noise gate 25. My microphone is wired differently. Grounding is at the plug. I will try to connect the cat tomorrow.
Thanks for the info. I don't think I am going to attempt a firmware update on this radio, as I would think the risk of bricking it is too high. As of a proper review I don't think I am going to do that. I have a couple of videos out on that radio, and more are coming.
@@LB0FI My radio shows version 1.02v (spose to have CAT) and I have a USB serial adaptor, I will try it out and let you know. For the time being I made a cable up for the Mic port following your diagram and have been getting lots of FT8 contacts some up to 7000 kms away with just a short random wire/tuner. This is a great radio for FT8 and JS8CALL.
I have version 1.02v of the firmware/ USB serial adaptor and have tried everything to get CAT to work to no avail. There seems to be data coming out of the radio but even using a serial terminal I could not make sense of it. I can get the USB serial adaptor to talk back to itself so I know that works but no joy from the radio... still using VOX and audio cables which seems to work fine.
