Hi Cristian,
Please upload a screen shot of your error.
?secondly, please check whether you have set the port and Port has recognised? the CH340G? usb interface.
Finally define the chip as atmega328, and if possible as old bootloader.
the Arduino Nano is also to be selected.

all the best
regards

I have restocked mic's, paddles and AGC's. The AGC doc's have been updated with the correction for the DP3T.

I am curious to the relationship of the IF-S to the calibration and/or the BFO. I have things set on the radio and I can hear pretty conversation clearly but my IF-S is set all the way to the right at 2000. I am guessing that it means I could still do some fine tuning somewhere.

Thanks for the help

Thanks for all the help everyone. I got it working pretty good and I can hear conversations very clearly.?

Thanks again

Tim, here's what I got this evening. Hopefully the numbers are good. They are similar to what I posted yesterday. The Vol-Hi measures are p-p done on an o-scope. There was a fair amount of noise at Vol-Hi maybe about 10mVp-p. It was tough getting a good connection.

Input?????? ADC???? A7(Vdc)??? Vol-hi(Vp-p)

-73dBm??????? 2???? 0.02??????? 20mV
-63dBm?????? 59???? 0.303?????? 72mV
-53dBm????? 158???? 0.795?????? 240mV
-43dBm????? 196???? 0.981?????? 660mV

I had to do the Vol-Hi measurements a second time after I realized it wouldn't work with the ADC on. (My turn to say, DOH)

Sascha,

maybe you can solve your problem of the noisy stepper motor using a low speed DC gear motor like this:

very low power consumption as well.

Hi everybody,

for the OMs who where interested in this project, I have made two videos of the controller in use with the uBITX.

The 2 or better 3 points I am still trying to work on / which need improvement are

1.) The sound intensity of the stepper motor. This is really annoying. The problem is i think that the capacitor gets pushed to hard by the pulses of the stepper which causes the vibration noises.

2.) For tuning, the loop controller switches the radio to AM and reduces power. Both functions are not supported by the uBITX.

a.) For getting a tuning signal i made the loop controller firmware change the mode to CW instead of AM for tuning.
However it is not working, i need to manually use a CW key (also called screwdriver) to get a usable signal.

b.) I think (depending on the band) 15 to 5 Watts is still to much output while tuning - or worse - while not having a good SWR.
I need to figure out an easy way to reduce output, which can be controlled via cat - maybe by manipulating the bias of the finals or by switching in an attenuater with a relays.

I have found that a 470 ohm in series with the 10 uF, seems to work well.

Its a big planet we live on. These rigs keep landing all over the world, from a small enterprise. Distract yourself by preparing everything for case assembly.? And explore what you may do later. Its a cool radio.

Ok thanks guys. I ordered it DHL. I just wanted to make sure the order went through.?

Which way did you order it? India post or DHL.? I ordered DHL and got full tracking info. If I remember right the website says if you order India post it is just the confirmation email no tracking.

I went through the same thing.? For me, I contacted the email provided in the PayPal notice.? They ultimately responded that I would get a notification when the item shipped, which I did a couple of days later.? I never did get a notification that the order was confirmed.

It was almost two weeks from order to shipping notification for me.? I assume that was due to all of the interest in the new v5 boards.? Once shipped it arrived soon there after.

I would send the email to the PayPal vendor link, and wait another week.? They may still be back logged on the boards.

FWIW

Hi all I ordered my kit about a week ago. I got a confirmation from PayPal but never got an order confirmation for the board. I looked on the website and there’s no way to contact them to make sure the order actually went through. Did the rest of you get an order confirmation.

Thanks
George

I am under the impression the documentation has been fixed.
That aside. R70 is a good place to be taking the audio from no issues there.
I am fairly confident the issue stems from the drive level on the v4's being lower then the agc expects. I think the simple solution is going to be add another amplifier stage before the audio in on the AGC but not having a board my self it is hard to test this.
Digger could I get the measurements of Vol-High with those same measurements?

Thanks for all replies. At least the small display I have responds to touch!

kbgluxford@...

any ideea haw to fix this error?!but whene i try to write on raduino i get message thar is writing but no mesaje is receive....i use another pc and the same problem...the ubitx is new,out from the box....

Thanks also, Tim, for these explanations. With the correct wiring instructions most of these questions didn't need to be answered.

As far as vol-high I'm taking it from the via hole at R70 which is just a few inches from the agc board.

I’m sorry to hear that.?
