Hard to tell, for what I know, there have been different production batches, each board was checked but may slightly behave differently from others. Current production should have solved relays issues

Dileep, sad to know yours is from Worldchips, too. Mine is working perfect. It seems your unit is defective.

All the best Balan. I had one such with TJC 3.5 display and Aliexpress supported my cause and of course I sought partial refund, as mian display still works and only the touch glass broken.

Thanks RAJ, It relieves us from the frustration regarding the issues under concern. wish all success, post launch and let the sat serve the ham community at large. regards sarma vu3zmv wrote:

Thanks VU2POP, Snowist and DV3RWR for your comments. Open an dispute with Worldchips, and I requested him to re-fund.

yep thats all that's needed.

Greetings, I have a ubitx unopened ver. 3 kit that I'am not going to build that I want to sell or perhaps trade. I also have an aluminum case for it. I would like to get $100 for all of it. You can

I'm not real familiar with his raduino board but looking at the schematic it appears to be just and enhanced raduino. Looks like he brings the i2c pins out to a header and a few other minor changes.

Lots of people do, but also very many do not. I have been using a Pi and a ?6 usb soundcard with leads directly to my ft891 with no issues at all. All of the input levels are controlled through the

That surprises me. I always use a sort of psk interface, i. e. isolating transformer (to avoid ground loops), fixed attenuator (the signal from the sound card might be too strong for an mic input),

Thanks.

Thanks Evan.

Thanks but there will be no transformer decoupling via signaling or similar, just straight from Pi to usb soundcard to rig.

The signaling has a serious capacitor built into it

Daimon, I have not connected anything other than a mic and amp to the uBitx, however I have a lot of experience with both Arduino's and Raspberry Pi's. Both are susceptible to high voltage on their

Hi Daimon I must admit I'd never thought of the potential problem you mention. However FWIW I use a Signalink USB between Raspberry Pi and ubitx and it all works fine in every mode I've tried. Cheers
