Ashhar Farhan
#ubitx
Does Ashhar Farhan answer emails sent to his HFSignals email account? ? I asked if there are any mods that need to be done to the current version you are shipping and if the JackAl add-on no longer needs the Raduino can the radio be ordered without it for a lower cost? ? With no reply in 9 days I just ordered the V4.

Re: uBITX V4.3
¿ªÔÆÌåÓýTHANK YOU. I THINK I WANT THE CEC SOFTWARE AND I WANT TO ADD A 3.5" NEXTION TOUCH DISPLAY. FIRST I NEED TO DOWNLOAD THE? DR LEE CODE INTO MY uBITX V4.3 THEN ADD THE 3.5" DISPLAY. I WILL TAKE IT ONE STEP AT A TIME. RIGHT NOW I AM ADDING MODS FOR THE WEAK AUDIO AND AGC. I AM RUNNING WIN7. THE TERMS LIKE HEX FILES, COMPILER ETC HAVE ME MYSTIFIED, BUT I WILL WORK ON IT.

Re: Is push pull hf amp has higher spectral purity
The stock Bitx40 has a problem with the 7.2MHz birdie not only on receive but also it produces a spur on transmit which does not meet fcc spec.
You could use it on 7.1MHz and below or change the vfo to high side and move the carrier oscillator to the other side of the filter (Allard's software). Whether you can do that depends on the xtal filter in your Bitx40. You may get lots of carrier and poor sideband rejection. The Bitx is a good entry into homebrew. You might get away with using it barefoot but take care if you want to push to higher power. 73 Brian. |

Re: uBITX V4.3
Arduino source files are .ino There is an arduino hex loader program that uses .hex file extensions I believe that the question is related to one of the various mods having stored the files in compressed mode, one of which uses .MD and? another .ICO.? He will need to look up extraction programs for the above compressed libraries (WinZip or 7Zip or similar).? I use WinZip. Evan AC9TU |

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. Evan AC9TU |

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. Jack, W8TEE

Re: UbitX audio hiss but no rx
¿ªÔÆÌåÓýOk, 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.

Re: Totally Absurd -- Farhan being questioned in a police station about doctored sat picture
Timothy Fidler
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. |

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.? |

¿ªÔÆÌåÓýOkay 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?Joe

Re: Spectrum purity of uBITX and BIT40
Simon
Dec 2???#62208??
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. Allison |
