Re: UbitX audio hiss but no rx

 

OK, I went back and looked through the prior emails to get a handle on what is going on.

First off, need to know the details of your build?
- uBitx, Bitx40, bitx20 which one if uBitx, then version (4 is the latest)
- Which version of Raduino (Nano) software are you using?
- Verify that you have installed the resistor for the CW keyer, or if using the CEC built in keyer the dual resistors for that
- did you change out the nano?

I am not sure that I can help, however will try with the above information.

What machine are you running on and with what op system? Those file types are for Microsoft Windows and your OS should have programs to unpack them if you're on a Windows machine. There are some converters out there, but I've never used them.

Re: UbitX audio hiss but no rx

Ok, so I've tried that, tried manually shorting the connections, nothing. I've clearly got something wrong in the wiring up process. I did get a more transmission out which I picked up on another radio, but it switched itself back to LSB.
Just checking, how robust are these boards? How likely is it that I've bloen a MOSFET or something?
I'm sure it's probably just a duff connection, but short of starting again I don't know what to do with it.

Best wishes

Another piece of class stupidity? : may years go I was working as an Instr engr in Melbourne on the telemetry and other matters to with a gas plant to go up in far north Pakistan.? This was wild west country where warlords not the? Pakistani army or police force made the law. included was a spread spectrum modem box that communicated from? here to there (I wont' say where for obvious reasons )? Data was gas flow rate , temperature that sort of thing.? Well someone in Pakistan suddenly had an idea that in a Paki/Indian war,? Ashan Farhan's brother/uncle? might lob over some rocket? (indirectly guided by the frequency hopping signal)? and wipe out the gas processing station.!!!? Pakistan does not have a great deal of natural gas so this would be a significant act.

? So we had to write a technical paper why this was next to impossible (did anyone ever read it ??)? and then got permission to put the link in. (Cable / Fibre optic is always? possible but is a much more expensive option if you have to trench for that one cable only).? So If I suddenly go QTE you know that the Paki secret police has got to me.

Quite how we in Melbourne (Aker Kvaerner at the time ) got the yellow jersey to do that job is a bit of a mystery.? There might have been some overseas aid component to it.. hard to say.? TEF

Re: God Speed on your flight Farhan

 


Buxton said Fox-1Cliff will share dispenser space with ExseedSat-1, a CubeSat built by an eight-person team at Exseed Space Innovations Private Limited, based in Hyderabad, India, and co-founded by Ashhar Farhan, VU2ESE, the designer of the ?BitX SSB/CW transceiver. Farhan and engineer Gurudatta Panda, VU3GDP, were on hand for the integration. ExseedSat-1 carries an Amateur Radio FM transponder and APRS digipeater, with a repeater, digipeater, and telemetry downlink of 145.900 MHz FM, and a repeater and digipeater uplink of 435.340 MHz.?

Okay so now for the questions, what is the name of the cubesat as I didn¡¯t catch and how can we track it? will our favorite satellite apps track its keplar data? What frequency is the transponder and is this all on a website?

I had the same problem.
(Well, at least I thought I did, turns out it was a PICNIC error).

Put the radio in CW mode, and find an AM station.

Hope that helps.

Re: Spectrum purity of uBITX and BIT40

Dec 2???

Seem to hear that self build, home brew is more relax under fcc laws than mass production factroy machine, to allow progress
in test, training, education, etc., in principle.? ?

NO.? The rules for factory and HB are the same.? They are not hard to meet but reasonable attempts to meet them are expected.

So far the relay is not the improved one.? Its not one its four and they are a pain to extract.??

Some people have built the uBitx as a ground up project using a self designed board or ugly (Manhattan, dead-bug style) on
a sheet of copper clad as a ground surface and the general result is much better.? Layout is everything.

Re: uBITX - Limiting power output

 

Charles French,

One way to find out... try it.? However use a good pot.? The shields go to one end of
the resistor and not to any ground near the pot and both shields are used at ground
where the pot was on the board.? Short leads and good lead dress keeping the two
shielded wires away from the board. The likely problem is RF feedback and oscillation

Me I'd dial it down as the sweet spot for passably decent IMD was found to be
around 2W anyway (for 80/40/20).

The current home brew radio I use with the 1208 is designed for it and the internal attenuator
was dialed down to 3db so all I needed the radio to deliver was about 3mW! Its dedicated to
the 1208.? Why?? Running the transverter and developing power to dump in resistors?resulted
in a power hungry system (nearly 40W in for about 10 out).? Doing a TRX specifically
for that lowered that to less than 26W (at 11W out) making it far more battery friendly.

Over the years I had my first Hb 20mSSB (3.5-4W),? WM20 (about 3w), and a TT505 Argonaut
(about 5W)? and all of them at one point or another drove the 1208 until I built a low low power
radio as a driver.? ?It iss a fun backup to my HF-6M (Eagle) and TT526 6n2 and five HB 6M
monoband radios.

Re: uBitx Function Button ERROR

 

I had removed the "Extra" purple wire that is an ADC input often used for an S meter.? I assume that you have a v3 or v4 ubitx (I have the version 4).? You explained in one of your posts that the problem goes away when you ground the output connector on the uBitx with your hand.? That is pointing to the RF coming back on the shield of the coax.? Do you have a 1:1 balun on the dipole?? If not, again I would look to grounding and adding the balun.? MFJ or others make both baluns and full cut antennas.

Have you tried grounding the case?

If problems persist, I would also look at adding ferrites on the control lines from the encoder to the Raduino board.? That was one of the things I tried, again, helped but the grounding and ferrites on the feed to the antenna were the things that solved it for me.

I would also verify that you are not over driving the audio: I could reduce the problem by lowering my mic gain.? This also reduces the power out, so may be just a function of the correct frequency and power getting back to the nano.

Since all was well with the plastic case, I am still leaning towards the RF coming back down the coax brain, and surrounding the nano.? If there is unbalanced RF on the braid, putting the uBitx in case that is not grounded may not have helped.

I had the same issue, however on 20m.? Traced it to rf riding the coax braid back from an off center fed dipole (MFJ-2010).? Solved it by grounding the shield before the radio, and placing a ferrite snap on core over the coax (RG8x) between the ground point and the connection to the radio.
?
Tried the ground only first, and it helped (could raise the power out to 6 watts), then added the ferrite to get it back to peak at 14 watts without causing the menu selection.? I did not have any issues on 40m.

Re: uBitx Function Button ERROR

 

RF pickup is a bit unpredictable. Long wire, more pickup

ONLY if they use ADC in way I described as no push button board circuit on web.

Then, 0.1uF on ADC line and a good grounding point, short leads on the
Arduino board

ADC is mega ohm high impedence input. Can add
from push button long line
10k ohm series
0.1 uF to ground

Hi, and thanks for the informations. I would like to say that my antenna is

socket. Can it be this happening because of the display wires ? And somebody
mentioned above about a capacitor of 0.1uF in the ADC line... should I put
this in paralel or in series with ADC line?
