Okay well then. Who will pay $100 for it? Kidding. It's sold! 73, Joe

For sale is the ubitx board and raduino. As mentioned in this thread, I couldn't get tx to work: https://groups.io/g/BITX20/message/38280 I don't have the diagnostic eq or time to figure out what the

Okay. Here's what I've got: I came home, turned on the ubitx which is still hooked up to a proper antenna. I set up my other radio, and stuck a 12" piece of wire in its antenna coax spot. I then keyed

Does it matter which side of the cap the antenna/lead is hooked to? If I were sitting at home instead of at work I'd probably just try both, but since I have a computer but not the radio here... And t

#ubitx

Me too! I even turned up the bias pots a little. Didn't help. I also removed the radio from the box and set it up again with jumpers, also with no effect. Raj I am not sure exactly what you mean re: p

Just got home from work and checked: brown wire properly hooked up. I measure 13.5v to the heatsink w/o the key down and ~13v with it keyed.

#ubitx

Right, so the directions say to go to min and then turn one pot until the current is 100mA higher, then to do the same w the other. Thats what I did, but my starting min current was 50mA lower than th

Actually, I was going to post this as a separate issue, but in the PA bias step my initial reading was outside the range mentioned in the directions. With both bias pots at fully clockwise, I measured

#ubitx

By PA supply wire, do you mean the wire to the speaker/headphone jack? If so, yes that's hooked up. It's working as a receiver (i.e. I'm copying activity on the bands) playing through a pair of headph

Okay I fiddled with all the torroids with the key down and saw no evidence of shorts. Also no activity on the power meter. I tested tx in 80, 40 and 20m with the same results on all. I heard signals o

#ubitx

It does indeed receive. I'll check out the toroids, thanks. It's funny you mention that as they looked a little flattened when I opened the kit. Joe

#ubitx

Should have noted: the radio does go into tx mode when the PTT is pressed and when the key is down.

Finally got around to putting my ubitx into a box, and I'm having trouble getting measurable output. I followed the bias tuneup procedure but when I got to the part where you HAAALLLLOWW into the mic

Sorry for the newb question, but will the ubitx be okay being fed by a 30amp 12v power supply? Mine is supposed to be delivered tomorrow and that's the PS I have handy (and I want to build it up immed

I should have added: I paid for the trackable shipping as well. Joe

Same boat here. Ordered on the at 2300z on the 9th. My Paypal transaction has no shipping number added as of a few min ago. Joe KD9JLV

I like all these antenna options, but I do have to find a way to operate w/o a tree. The MI parks ask people not to run anything up into trees because of concerns about moving parasites around. I am t

Very nice! I like that arrangement even better than the one I linked to. Question: how did you anchor the plate everything is mounted to to the case?

I posted this question to another forum and didn't get much support for the idea, so I figure I'll ask here: "I'd like to get involved with some of the OTA groups -- Michigan's three year Parks On the
