Excellent

That will slow down the add me to the list.

I will order when you get caught up.

Eric,

Nice upgrades. ?I am doing these for another Ham. ?He opted for the LaserBeams-Vari filter with the added display for filter control.

?

I suggest that you try Mark’s calibration software. ?That should be easier than the manual method, and may be the only option if you cannot switch out the digital audio filter. ?It would be bear impossible to zero beat WWV with the filter.

KK7BCO,

?

The article you are using is for the v5 and earlier uBITX. ?The P1 connector did provide separate feeds to the PA and the rest of the radio. ?On the v6, The two pins are connected together under the plug. ?You could remove the connector, cut the trace, and then reinstall the connector.

?

It is not worth doing just to provide separate fusing. ?If you want to get a little more power out, you can provide separate power to the PA, maybe 20 volts. ?That requires two power supplies or one higher voltage and a buck converter to drop to 12 volts for the rest of the radio.

?

3 amps is the correct fuse for the radio when operating on 13.8 volts. ?The maximum current that I have measured is 2.5 amps.

Hello,

Last time I used my uBitx the magic smoke was released. The radio was idling, just listening to something (probably FT8) when I noticed a glow in the room and pulled the plug. It looks like I may have just burnt the trace nearest the edge on the underside, which I think is the main power rail to the switch/pot. I repaired this today and the unit powers on, but I won't test it properly until it is back in the case with everything connected properly.

?

On here there is mention of connecting separate fuses for the main board and the finals, using the P1 header. My brain gets confused by schematics which have breakouts, so I do not understand how P1 is connected: the article suggests that 3 connects to ground (correct) and that 1 and 2 connect to the main board power rail and the finals rail (not sure which is which). My DVM probing is showing the schematic's suggestion that 1 and 2 are connected rather than being separate.

?

So, my question to anyone who has performed this addition, or is better understanding of the schematic, is whether I should disconnect the center pin of the barrel connector and connect two wires running to the two fuses, then respectively connected to pins 1 and 2 on P1, or whether I should be tapping a trace elsewhere for the finals, or just run two fuses in series (!?). Or just a single 3A (or 5A) fuse.

?

When I had my magic smoke episode I did have a 5A fuse, but it may have been one of questionable origin in the power distribution block. I have subsequently replaced all my fuses with Littlefuse things, since they do seem to burn when they should.

?

Thank you,

KK7BCO

I no longer have my confirmation email so after seeing this thread I emailed sales. ?Maybe I will see mine this week. ?Who knows.

Probably after the current batch is all out, going to their purchasers, and when HFSignals has had a chance to replenish stock of necessary components...and perhaps they may get some sleep ?. I'm pretty sure some of the crew isn't ready for crunch time again so soon.?

When the new orders will be accepted?

Search Emails for "hfsignals" ? Is auto correct really helpful???? I dunno.?

There is a link in the order confirmation from HF Signal. Do a search in your emails for resigns.

Where do you check for zbitx status?

Enjoy, mine still processing?

Hello Eric,

?

What version of software are you using?? If the HFSignals stock version is used, the calibration process may be done using the transmitter.? An option is to load the KD8CEC software and use Memory Manager to save calibration value.?

?

Another alternative is the software from Mark, AJ6CU, which has a calibration option:

Hi,

I have massive problem with my uBITX v5 for Calibrating.

When I set the Calibration:
eg +10 for the accurate 700 Hz on 14996.000 in USB
then press the Mic Button - says calib set.
goes back to receive - seems ok.
But if I turn the RIG off and on again - the frequency is much lower:
eg bay pressing Button 14996.000 - after boot 14664.650

It look like the value is not really set, only temporary in RAM.

I had this problems since I have this RIG.
Also the Rig is really deaf.. only the most strong stations are received
TX - I must on a given QRG go up for abt 300 Hz then is on the QRG for transmitting to the partners QRG

I spent hours for resolving this - but no result....
Is there not a point ( Tp on the PCB ) where I can set the Calibration ?
Have an Frequency counter/generator here, also other RIGS with are 100% accurancy.

Arriving Wednesday - yay!
