New uBITX Ver. 6 Assembled Today
I assembled my V6 full kit today.? No nut for the BNC connector, no sticky on the feet and the feet are too large to work with screw positions, volume knob can be attached but just barely.? Those are no big deals.? Maybe you an help me with some electrical issues listed below.
My problems are electrical: (1) When mic is plugged in for a minute or so, the radio will cycle to TX at the same rate as the CW speed.? Unplugging the mic stops the TX cycling, but it will start up again at unexpected times.? Can't make this happen when moving the mic/cord, so it is not a faulty cable or switch. (2) My radio is on USB when it says LSB on 40 meters.? The radio is on USB when it says LSB on 20 meters.? Other bands not checked.? Confirmed this issue with on-air contacts. (3) In CW mode USB and LSB are the same with no sideband suppression.? That's OK, but where do you tune to zero beat a station? Bert N8NN |
Did I break my V6?
#ubitx
My V6 arrived yesterday afternoon. I assembled it that evening, hooked up an antenna and power supply, and took it for a receive-only spin.
I ran the audio-out into my laptop and monitored FT8 with wsjt-x. Everything worked beautifully. Then I got the brilliant idea to try CAT control as well. I scanned some posts here, and connected a USB cable from the extender to my laptop. After some fiddling with the radio settings in wsjt-x, I was able to control the rig. Then I disconnected the USB cable, and that's when things went south. The tft screen went blank, and would not come back up when the rig was turned off or on. I reconnected the USB cable and the raduino and tft power up again. Receive turns on and off with the power knob. Logic says something is disrupting the 5 volts from the main board to the raduino. It was getting late at this point so I decided to table it for the night and dig in this evening after work. Am I an idiot, and did I break my new radio? Mike KD7ZPC |
Re: uBITX V6 heat sink temperature
60C degrees don't seem to me really too hot but actually I have no much experience with finals. The CPU temperature of my laptop is about 75C degrees. Il 27/dic/2019 20:20, "Joel Caulkins/N6ALT" <caulktel@...> ha scritto: It has the heat sink screwed on and is tight, the fact that the heat sink is so hot means it's working, it's transferring the heat. Maybe I'll change the regulator to a new one to and see if it runs any cooler. |

¿ªÔÆÌåÓýI agree.EXCEPT I screwed the feet on, the screws were short, so I pushed.. and put the head of the screw all the way thru the foot. Besides a larger nut for the BNC, I will get 4 stick on feet. And I thought it was just me.

I believe that the 3x4mm are for the display, and the 3x8mm work fine for the places it says 10mm. Second, the main board doesn't line up with the screw holes on the chassis. At best, three of the four screws go in. I chose to omit M2 because the BNC connector would hold it in place (see for how far off it is, not a lot but enough that the screw doesn't fit) Third, the front plate hinges on the 3.5mm inputs and it's very hard to screw in both the top and bottom.? is how far off the top of the plate is if I screw in the bottom two screws. Fourth, the volume/power control doesn't stick out far enough to properly put the knob on, see .

Fifth, there's no mention of the feet anywhere in the instructions, and even if there was, it wouldn't matter because the screws aren't long enough to go through the feet into the bottom screws of the top and bottom plates. Sixth, in the instructions it says to attach the antenna last, after the display. This makes the antenna connector incredibly hard to attach, it should be attached before the display (and probably even before the front panel goes on, it's much easier that way.

OK
That's AFAIK
Being a lazy American and ignorant of all things metric, I just used the screws that seemed appropriate -short ones for display, longer ones everywhere else... I had leftovers of everything included.
I had no problem securing the main board to the four points on the base.
The 3.5mm jacks protrude sufficiently (as shown in HFSIGNALS website photos), I expected the nuts from the jack to anchor jacks on faceplate, but there was not enough threads to attach the nuts.
Agreed. By knob is exceptionally close to case, seems secure, but I'm Probably babying it.
I assume the feet only attach with adhesive - all the available screw holes are too close to edge - I chose to leave them off.
Do you mean the speaker connector? I had no issue attaching last, but it would be better to attach it earlier in construction.
Common issue, I had no BNC nut either.

Several Quality Control issues with ubitx v6

Re: uBITX v6 kit makes tones
¿ªÔÆÌåÓý+1 for missing BNC nut.The 1/8" (3.5mm) jacks on the front included nuts, but the jacks don't extend far enough to secure the nuts on the front panel. Not a problem, but now I've got three tiny nuts extra. Also, the only tools I needed were: "regular" (neither large nor small) Phillips head screwdriver "Small" (neither regular nor tiny) slit screwdriver Pair of pliers/needle nose pliers? The "small" screwdriver is needed to secure the supplied knobs on the control shafts. The "regular" screwdriver is for all other screws on the case, and the needle nose pliers are needed to hold nuts while you secure the speaker to the lid.

Re: uBITX V6 heat sink temperature
I hope the heatsink is clipped on. I have been running the radio continuously for a month now. No harm done. In an earlier version, I was using a switching regulator. It was horribly noisy. I just took the lazy way out. - f On Fri 27 Dec, 2019, 10:41 PM Joel Caulkins/N6ALT, <caulktel@...> wrote: Hi all, |

¿ªÔÆÌåÓý¡°Tighten the large nut around the BNC socket.¡± ? I received two ¡°large¡± nuts. Put one on the Encoder. Since both are the same size nuts, it would not fit on the BNC socket. ? The packing slip for the v6 kit lists #17 Encoder nut, but does not list a nut for the BNC. ? Off to Ace Hardware.. ? Kent ? From: [email protected] <[email protected]> On Behalf Of Ken Hansen

uBITX V6 heat sink temperature
Hi all,
I have my V6 all hooked up and calibrated and have checked into a few nets with my own home brew mic, the supplied one got bad reports, however I have noticed that the 5 volt regulator heat sink is running at 142 degrees F or 61.1 C. That seems hot to me. Anyone else? Joel N6ALT |
