Re: New uBITX Ver. 6 Assembled Today
just to throw my own experience in here, I was suspecting the mic was bad too, but I also didn't have a proper low power meter. This morning I found an old power meter with a 10W range and tested again. No power out on SSB. I also find the mic I used with my version 3, and I see about 4 Watts out with a hearty Hallooooo! Into the mic.? I'll take it apart this weekend and see what's up, but I also have 2 of the Pacific Antenna qrpkits mics to assemble and I hear good things about those.? I'll report back.?

Re: uBITX V6.0 For Sale
Ashhar/Hans
hams everywhere are truly blessed to experience fine radios.? all was meant to try to 'redeem' a thread focusing on concerns with the size etc of the uBITX (one can wonder where the term micro comes from?) - so I merely invited him to consider the QSX.? I appreciate the correct path each of you has taken to benefit a vast number of ham ops.? my v4 ubitx and QCX are doing well, ditto for the U3S.? (I hope to finally check how the v4 works with shielded inductors and an added xtal filter, but I may not have spur data for a while - but if the rig works decently I suspect it will be pretty good also with spurious).? those unexpected features on the QSX are quite welcome.? sometimes I get concerned that those of us in the West dominate the list - I have learned wonderful info from Raj and Sunil and others in India and other places.? please everyone, enjoy your building and radiations.? belated happy 2020, Curt wb8yyy |
Re: uBITX V6.0 For Sale
BUT, can you do things like add a new modulation scheme, like FreeDV or other codecs? It seems that would require SDR-level coding, something that couldn't be easily bolted on at the UI level. Would there be a codec "plug-in" interface? 73, -- Dave, N8SBE

A good SWR meter can be got from Ebay for not very much. I have never owned an antenna analyzer - a SWR meter works just fine for a lot less. Alex Netherton On Thu, Jan 9, 2020 at 8:34 AM Vaughn <vlkteach@...> wrote:

Re: Need to Calibrate the V6
#v6
Thanks Ashhar, that got it done although I had to find WWV on 5mhz since the 10mhz just wasn't strong here.?
Some thoughts: Would it be possible/reasonable for you to store the BFO and Freq adjustment numbers in EEPROM?? I had to go back and forth from setup to regular operation to finally get the v6 accurately at zero beat and each time the BFO and Freq adjustment numbers would revert to their defaults and I was starting from scratch again.? Also, the tuning speed could be damped down a bit; it seems far too jumpy right now.... |

I experience similar difficulties with settings and freqs shifting during the button press. But too many miles for me to get a ham/electronic hobbyists candy store as it were hihi.? Only one here was a morphed Radio Shack (aka TheSource) and since Bell Globemedia took it over all the hobbyist candy inventory has been removed; now they just flog cell phones TV's and Express Vu Sat TV. selection for us is really gone downhill.

Good call. It¡¯s just a contact closure so you could do both in parallel if you wanted. :-)

"I've had difficulties getting into the setup menu with a long push, because the encoder is really sensitive." This is exactly why, when I assembled my v5 uBITX, I didn't use the push shiwtch on the encoder, but instead connected a separate red SPST push switch on the front panel of the radio. Works like a charm with no interference to or from the encoder. 73, ... Martin VE3OAT |

Dope. Read Andy's stuff but not the initial prompt. I don't have any suggestions beyond xloader for Windows and using the Arduino IDE or avrdude for anything else

If you just need to load a hex, avrdude from the command prompt should work too:
That assumes you have avrdude installed and are comfortable running command line prompts, though. No GUI. Reed |

¿ªÔÆÌåÓýYou might try Xloader if the PC's or laptops are running windoze
OS's; no equivalent for linux flavors I have found yet. I just put arduino IDE into a linux box and tried to get a hex file imported into it but no go. I did a quick compile / export sketch, similar code to what is in the Utube video link below, to duplicate the resetting of the ubitx nano using an android phone USB link because, as Reed and others have pointed out the way the nano is mounted the reset button is not readily accessible or visible so the arduinodroid seemed like a good option. also need a Micro USB Male to Mini USB Female Data Sync &
Charge Adapter Cable to connect nano to phone
One would be well advised to do all your familiarization with
the arduino IDE without the nano in the uBITx connected as the IDE
has some features that do a couple of things in a sequence and
then upload your practse sketches. I use the export sketches
options to obtain compilations and hex files to study or work
with. Maybe invest in one of the cheap arduino uno boards or kits
to do experimenting.
Here are a few
----> YouTube Tutorial Arduino software development tool
; IDE GUI ( a couple of F bombs and Hell at start otherwise informative) ; hardware ; general overview tutorial ; vid tutorial aeduino coding
more vid tutorials NOOBIES might want to go through first before embarking on blind mouseclikkin' fingerpokin :
I had received a hex file from Reed and hence I am trying to find a work around to upload it from my linux box. I spent a few hours watching video tutorials so haven't yet got a good solution for using my linux box to do this; I have a nice large (32") bright display on it to be able to code in arduino sketches with ease rather than tiny little dim laptop screens on battery. It looks like one needs all three files as shown in att pic to be
able to view the actual sketch code in the arduino IDE window; and
the the two hex files to upload directly ( one with and one
without the bootloader) an .ino and 2 .hex files.

I know about AvrDude and USBtiny and similar methods of getting HEX into the Nano and that's fine for us semi-technical types.? What I have been looking for and unable to find is any super simple system that will use the USB connection and simple software to program the Nano rather than requiring the Nano to be pulled out of the radio so that it can be used with a burner like USBtiny. Setting up the Arduino IDE is beyond some of the people I'm trying to help so I'm looking for a way for others to load a HEX file without pulling the Nano out of the radio.? |

Dave, I wasn't sure if it would be useful. Now that many have confirmed it to be so, I will link it up in a day. - f On Thu 9 Jan, 2020, 10:59 PM Dave New, <n8sbe@...> wrote:
