Fantastic delivery - left India Wednesday and it will be on the air Friday evening in California!
Just an amazing little rig. Super job everyone!
Just have to get my antenna back up from storm damage this afternoon, then uBITX will be on the air soon!

Moving to an i2c LCD would help.

Diz has a nice kit for an inline SWR/Power indicator,? $12, good up to 100W.
If we had a couple spare analog pins at the Raduino, could use that for sensing.

I built this QRP one from eBay ordered parts. Randy does a nice job explaining the build. You can also take power measurements using the Elecraft owners manual chart. See ? Sent from Mike's iPad WA1MAD

Re: how to coil your own cables
Thanks. A while back I watched a YouTube on same subject. After the hearing the guy spun it backwards to make it snugger (if that's a word)

Maybe just be aware
that some enamel is the same colour as shiny copper. Test with
your multimeter to be sure.

Re: Rugged Case Options?
#ubitx
I ordered a couple of these, good price:
? ??
No idea how thick the sheet metal is.
The bigger one you ordered would be better if you want to add stuff inside, and/or want more panel space.
Mine will be cramped across the width for a uBitx, but has room towards the rear for a battery and SWR detector.
Will report back once I get my hands on it.

I have an SWR bridge from kitsandparts but wouldn't know where to start to get a nano to read from it and output on oled. I have everything but the code experience I keep trying but just no good with code.

Nice.
I assume they are 1W parts.
With shorter leads, might work better at VHF if that's of interest.
From what I see on Mouser, the surface mount parts are cheaper than the old style radial leaded parts,
??
Could do a small circuit board with pads for those surface mount resistors and the diode rectifier circuit.
Holes cut in the circuit board allow oil to contact the bottom of the surface mount resistors too.
Not sure how well connectors would do in that oil, so just solder any wires and coax to the board.
Coax ties into the middle of the board, resistors radiate out for minimum trace lengths.
I need a good dummy load.

Mine ordered on the 9th was shipped on the 15th
and arrived on the 18th
one day earlier that predicted.
I'm the one who came home from work and found my uBitX wrapped
and under the Christmas tree. I'm told by wifey that it will stay
there until
I get moved over to the nice list!

Hi Joe,
Same situation here..Placed order, got reply from PayPal, but no acknowlegement from HFSigs..There doesnt seem to be any link or address to email them to find out the status either..So keeping my fingers crossed for now..I would expect some DHL tracking link sometime during the process. I see some guys are getting their radios. And if worse comes to worse I just file a claim with paypal and they'll get the money back..But I would rather have the radio.
73 es keep us posted,

Does anyone know if there's a site to find the status of an order? I placed an order for a uBITX last week. and, aside from the immediate confirmation that the e-commerce site got my order and charged my card, there has been no feedback from HF Signals about confirmation and when the order will ship. Given the popularity this unit is likely to gain, I think regular updates about order status is important.

Jack, Thanks.
I really need to make time to read your books.? I am sure I will, once I actually start playing with the Nano.
Thanks again.

ubitx - Possible to receive 630 meters?
#ubitx
Hi,
I will be putting my ubitx together after Christmas but was curious if it is possible to modify it to receive 630 meters???
I already plan on building a lpf for 160 meters, so I will build one for 630 meters as well.
Any thoughts or suggestions?
Thanks

Jack,
?Any chance at the code? I have pretty much all of that ready to go and a dummy load that would love that as a add on. Could it be used inline for active monitoring of output? I need a good meter but no radio funds outside spare parts at this time.
