Nope...not going to risk the HF rig at all. Five days and we're no closer to finding out anything except I bought junk. I appreciate the help from everyone...especially Gordon. You spent a lot of time walking me through things, doing sketches, etc and I really appreciate it. We started off on the wrong foot, but you're a good man. But, this thing isn't going to work and I'll never be able to fix it. My daughter knows I tried and she'll have to be satisfied with the pre-built one I bought....however it's configured. I'm not touching a thing on it. |
uBITX works!
Simply couldn't resist haywiring the board and trying it out after getting it today! Despite the precautions about trimming leads, I left them untrimmed and all worked well! Photo enclosed... packaging, well, it's so much fun this way... no, I'll work on something...
On 40 and 80 meters it seems to receive very nicely for the broad filter on CW - no mike hooked up yet. Tuning pretty smooth and functions easy to figure out. Worked a few stations on 40 and 80 for the Wednesday night (Thursday UTC) CWT contest, and it was not too hard to pick stations apart even with the SSB width filter - above all, the sound was clean with several stations in the passband so we're definitely on the right track. Heard some pretty weak stations down to the noise and pulled out a QRPer I could barely read. I was happy to note the rig tuned down below 3.5 MHz down to the 160 meter band and into the upper AM broadcast band. Issues to work on - and I of course will contribute. None are deal breakers for the kind of rig this is, but of course we can constantly help improve: Pretty hard pop when it goes into transmit. The keyer is cleverly implemented, but isn't very forgiving of mis-timings in transition from dit to dah. I'm sure there are limits with the multiple voltage scheme (plus you don't get iambic). Straight keying was glitchy - whether it was my contacts or whatever, it kept going unresponsive or responding oddly to key presses. Attaching my good old Wilderness Radio KC-1 counter/keyer made for good CW. The only menu function that didn't work for me was changing the CW tone - tone changed but grounding PTT didn't make the frequency enter. Other functions where grounding the PTT line was required to confirm worked fine. All in all - elegant simplicity overall, with just a few things the community can help improve - which is part of the point! Thank you for this design and getting such a radio board out into the hands of the world! John Seboldt K0JD Milwaukee, WI |

开云体育Hearing it over the
time signal is why it is being suggested that you disconnect
the dipole from your main rig and temporarily replace it with
a short wire. You won't harm the Yaesu at he power levels being produced by the Raduino.You are only using the Yaesu to "sniff" the output from the Raduino, in the absence of any other RF test gear. Bill, VK7MX On 21/12/2017 3:53 PM,

Re: Help! I think I may have just ruined my 9 year old's Chanukah
I just tried to start the troubleshooting video. First, it's outdated. Second, touching the antenna with a wire caused it to pop and crackle until I put it firm, but I didn't get increased noise.
This thing is just junk. I wasted my money |
Re: uBITX working, question about power, PTT pop, LOUD headphone output

Correction. PTT does nothing but the encoder button only exits the menu. The change to CW tone does not take.

That stupid time station is way too loud. I have tried it though with the plugs still in....only unplugging it from the LCD so I could raise it up. Still didn't hear it. |

Re: Help! I think I may have just ruined my 9 year old's Chanukah
开云体育actually, that pic shows 5 caps and 2 resistors. I suugest that it would be useful in these posts if you refer to components by their numbers on the pcb, for example C1, C6 or C5 for those closest to the Si chip. That will narrow down the effort for those of us looking to reply, as it is our normal mode of referring to them. Bill, VK7MX On 21/12/2017 2:47 PM, William R

开云体育Caps look fine to
me. The two resistors can't really be seen from the at view,
as far as the solder joins closest to the Si5153 are concerned
but I would suspect that they are also OK. On 21/12/2017 2:16 PM,

When you have the raduino out of the case, is the display no longer connected?

If you have it connected and tune to a freq, then disconnect it that freq is lost unless the tuning pot is coming with it. It should be at either extreme 7.0 or 7.3 but I'm not 100% sure what the extremes are in that. So you'll need to check near 5.000 and 4.700 but that's not a guarantee. The tuning pot is connected between ground and +5 volts. When you tune it it varies the voltage going into on of the analog ports on the nano. That voltage is mapped and a freq is derived from that. Then the freq info is sent to the Si chip to make that freq happen. Without the pot connected that analog port is floating. What do you have for an antenna on the HF rig?

Something just occurred to me. Without the raduino connected in the case it's still going to do something. You just won't be able to vary the freq. So with it connected to the USB, see if Farhan's sketch works on 12.000 - whatever freq is displayed, or somewhere close to it. I can't tell which frequency is displayed, but I have tuned it to a frequency, taken it out, hooked it up to USB and then tried to find it. I did 12,000 - displayed frequency. Never found it. ? I did remove the caps. They look fine to me. |
