K5AID smoke test successful

Well, I connected my windom antenna heard some 40 meter cw, but I also heard some things like birdies and so my first thought would be to check for cold solders, shorten up wire runs, and twist cables to minimize noise pickup. I stumbled into the menu, and I hope I didn't mess something up...got a message of "calibration? set!" But I have no idea how I got there, or w hf at I did.? Stock firmware as shipped on raduino...no mods yet.

A new rig can sound different. I doubt you did anything to calibration by accident. Learn how the menus work on your own for all but calibration. Do listen to different bands. Enjoy the rig a bit before concluding anything is amiss. Since you and I didn't solder all these parts, I doubt there are any solder issues. Curt |

Hi Curt, ????????????? From Near STONEHENGE in the uk would you recommend the v5 ubitx????? if so what mods..regards Dave G0AYD. On Sat, 23 Mar 2019 at 11:08, Curt via Groups.Io <wb8yyy=[email protected]> wrote: Kelly |

I have no clue what might be lurking there in that ancient structure -- okay never mind its just rock!? I certainly recommend the uBITX as a cool radio curiosity.? I myself have a v4, I can't vouch for the degree of improvement (particularly in spurious) for the v5.? We honestly need more data, but here versus the US regulations a typical ubitx will be compliant on a few bands, marginally compliant on a few - and likely as much as 10 dB or more out of compliance.? As the community obtains and compiles data, hopefully reliable recipes will emerge.? My v4 is now fully compliant on the lower bands using an added relay board, but it is not yet compliant on the higher bands.? My rig also has a mod to reduce the sidetone level.? I use my ubitx with an external audio filter for CW, and I have an AGC circuit installed.? That's all.? Curt |

Hello Curt, ?????????????? Stonehenge is 4,500 years old and the discussion why it was built and where did the stones comes from is still open for debate.Its created alot of controvasy regarding the main road that runs 400 yards away,they have been discussing a bypass for oer 40 years now prices for this started off at ?1.5 million last year this has gone up to ?33 billion and still nothings progressed any further and the road past the monument vehicles are nose to tail most days.The summer will soon be with us and then traffis tail backs will be up to 8 miles...I had to drive past it to get to work 4 days a week for 38 years !!!!.. They recently built some houses 3 miles west of stonehenge and whilst digging the foundations for the houses found a skeleton when the acheologists dug him out he had flint arrow heads a knife and remnants of a bow.and boots,dna tests showed he originated from the swiss alps. His skeleton and finds are now situated in Sadlisbury museum.Anyway you can google all information. Right i think i shall continue to read the comments on v5 and then decide should i purchase one or not I have a local friend who has a vesion 4 and not impressed you have to modify it to have some semblance of decent received audio.I think i may place an advert for a version 3 and see what transpires.Have a good weekend.Dave G0AYD..

The uBitx is good for what it is, a working starting point with which to experiment. Some bands and modes may not meet regs so not a good idea to add a linear amp for high power. Comes mostly assembled, firmware and hardware are all easily hacked. If you want an appliance that just works, figure five times the price. > .I think i may place an advert for a version 3 and see what transpires. Not sure why.? The v5 is apparently better than the v3 and v4. The audio amp on v4 was less than ideal, but is easily replaced with the v5's LM386 for around $1US.? ? ?? Not yet available, but the QRP-Labs QSX SSB/CW/Digital HF transceiver looks promising.? Will require much more assembly, firmware is not open source, not so easily hacked. This will not be an easy kit for the first time builder. But has lots of additional features. The older QCX single-band CW rig from QRP-Labs has been very well received. We keep our Concretehenge in much better repair, and our skeletons are older:? ? ;-) ? ?? ? ??

interesting stories there about ancient and modern coexisting.? here in US our feds got wild idea to put too many jobs in its vicinity.? no matter how much roadbuilding gets done, it isn't enough.? the ubitx is much more about the journey then the destination.? that a well performing rig can be mass produced with so little is nice.? mine hears just as well as my K2 in light to moderate traffic.? any of its versions can make a nice radio.? only real weakness is no one is yet kitting for sale the stuff to fix the spurious.? our club here is assembling now more than 23 units.? we kitted a simple relay board to add isolation at the LPF network - 4 out of 4 so far (mine included) are successful.? no clear cure yet on improving 45 MHz IF related mixing spurs - the crystal filter solution disrupted 40m CW, the simple LC filter in v5 isn't enough in my rig.? remember its the journey!? my rig is working nicely now on all the lower bands.? 73 Curt |
¿ªÔÆÌåÓýI FINISHED MY VER 5.1 AND IT IS WORKING VERY WELL. I DRIVE THE SPEAKER WITH NO AMP OTHER THAN THE 386 FROM THE RIG. PLENTY OF VOLUME. I ADDED? AGC BOARD FROM SUNIL. FOUND A S-METER ON EBAY (CB METER) AND WORKS WELL. MANY OLD PROBLEMS FIXED WITH VER 5.1 NO MORE POPS. AUDIO GOOD. I USE A UNIDEN CB MIC (ELECTRET). THE FAN MADE A NOISE WHEN GOING FROM TX TO RECEIVE. I INTERFACED THE FAN WITH A SMALL RELAY TO ISOLATE.? ADDED A SMALL SPDT SWITCH TO THE FRONT OF RIG FOR FAST AND SLOW AGC. I DID NOTICE THAT THE BIAS OF 100 mA WAS TOO MUCH. I USE 30 mA FOR EACH TRANSISTOR PA. IT NOW GIVES ME 6 WATTS CW AND 12 WATTS FOR SSB. ALSO MUCH MORE STABLE. I CAN DRIVE MY SOLID STATE AMP AND GET 300 WATTS OUT WHEN NEEDED.
