As posted in the original sale thread here is the site where all this came from: AGC

Re: Second batch of uBITX shipping? #ubitx

Gary Shriver
 

I sent them an email last week asking where I was in the line up and when I might expect to receive my ubitx.  I ordered on January 13th.   This is what they sent me after my email last week:

 

We are currently shipping orders received on dec 20th. It will take  about 2-3 weeks for us to ship your order. Tracking details will be updated once the shipment is done.

 

HfSignals Team

 

Sounds like they might be catching up a bit.  I read this to say I could expect it to be shipped in 2-3 weeks.

 

Just an FYI for you guys.

73-Gary

Keep Calm my friend Aurélio, I ordered my uBitx in Dec 23 and dont receive notice from hfsignals at this moment, I just follow the dispatch news here in the list.


I believe that next week it will be my turn.

Re: AGC kits

Does anyone know what the typical output level of the first AF amp should be for a strong signal? I built the AGC amp shown in the message by Joe Puma and the AF output begins to distort with an input of 300mv to 350mv RMS. I haven't yet built a spreadsheet to see how much AGC action is provided as the AF level goes up. Maybe I can get to that tomorrow. I don't have any way to sweep the amplitude of the input AF, only the frequency. So I'll have to build everything up manually a point at a time in order to see what compression is provided.

I would think they have bitx 40 in stock I am guessing ubix may be delaying things chris

Glad you received yours.

I ordered a BITX40 with Raduino on Feb 7.

PayPal notified me a few minutes later.

So far nothing came from HFSIGS.

Just sent an inquiry to teamhfsigs@...,

waiting for a reply.

BTW, is the BITX40 sent from stock?

Same here. I still need a case and I'm hoping by the time my uBITX shows we'll have a path for flatter PA drive (I have some IRF510's and RD16's in a bag).

ok now that I slept for 12 hours doing better.  ok square pad # 12v---pin #3 no volts---pin5 no volts---pin8--0 volts----pin#9--no volts---pin#12---12 volts---pin #14 12 volts---pin #16--12 volts.  hop that is correct.   with PCB & Radunio unplugged measured connunity, connunity ok.   checked k3 no voltage on any pins on receive.  Thanks 73's de AC8XZ

Yup. I’m still waiting for a case option to become available so I have time anyway

Re: [SPAM] [BITX20] A SWR power bridge for uBITX

K9HZ <bill@...>
 

Building SWR bridges is pretty easy for most people here and there are many examples on the internet to follow if you want one.  The difficulty with the uBITx in its current form is finding a way to bring the Vfor and Vref signals into the Radurino for calculation and display.  You either have to do some pin juggling… or move some current analog features to the I2C buss.  That’s where the challenge is.

Re: ubitx project

Andrés Moreno
 

The project is on the right track.
Everything is already in a metal box (cookie), it is already possible to transmit, getting about 12W in 40m. and approximately 7 in 20m. For the other bands I do not have antennas.
QSO's in 40m are relatively easy to do, depending on the propagation, but even with my precarious antenna I have been able to perform QSO's with EA8 and HB9, in addition to practically all EA. Keep in mind that I use a mic preamp that has some compression.
The front-end has changed, being governed by an arduino mega2560 pro and a 2.4 "touch screen.
It is possible to adjust the frequencies of BFO, IF, CW Tone and an offset if necessary for the VFO. For the Si5351 the calibration factor and the outputs can be adjusted.
As a disadvantage, this Arduino works at 16MHz and it seems that, together with the screen, it introduces some noise. Working now to eliminate it.
I just uploaded a small video showing all that:      https://www.youtube.com/watch?v=18RdGJ-0sto
or search for "ubitx EB7ME" on YouTube

Thank you very much Farhan for your great idea.

Regards

I ordered on Jan 17th. They said 3 weeks before my item ships 2 weeks ago.  Yikes, I’m in for the long haul. 😩

Re: A SWR power bridge for uBITX

 

I just picked up this kit works great stock up to 15W if you have a pic programmer you can flash the SWM3 hex and get it to over 40W.

 I have tested this to 50w with the SWM3 firmware and it works great, for the price its hard to beat. Next to the Oak Hills meter its worth every penny.

just a note on the build the core is 11 wraps a side not 25.

Re: AGC kits

So there shouldn't be a 10K between the diode and the gate of the fet?

There isn't one on the original schematic and there aren't any pads on the circuit boards for one either.
