Ubitx and 60 meters

Walter Robard Seiler <waltrseiler@...>
 

Having put together the bitx40 and enjoying that I decided to purchase the ubitx.

I don’t  see any posts on USB on 60 meters, how is upper side and selected on this band.

In the documentation it says that USB is automatically selected after 10 MHz

Thanks

Hi Walt,
You would use the function switch, built into the encoder, to go into the menu and select USB.  That is all that has to be done.

My uBITX is alive!!

David Robertson <kd1na363@...>
 

Everyone.
Last night my uBITX took ti's first breath of life. Even worked a couple of QSOs. Attached are some pictures. Please note that I installed the 4.7K resister on the radinio board for CW pull up instead of installing it in the wiring with the CW jack on the front panel. Because of the case size I removed the heat sinks from the finals and using mica insulators I mounted them to the back panel. The heat sinks that were supplied had metal ridges on the back that had to be removed so they could mount flat on the bolts that fastened the finals to the rear panel.

The radio works on 80 through 10 meters with decreasing power as you go up in frequency. I get about 15 watts out on 80 down to 5 watts on 20.

The frequency calibration seems to be very close. In performing the bias adjustment I discovered that I could only adjust the current for each final to about 83 ma with the pot set fully CCW. So to even the shared current of the two finals I adjusted them to 60ma each with the total of 120 final bias current. The little voltage regulator in the final circuit was working correctly supplying 5 Volts to the bias circuit during transmit. Though this radio is not in the same league as my Elecraft equipment it is a radio I can have a lot of fun with.

Looks pretty good David, but where you have the Raduino mounted to the display and mounted off the main board, you really should rework the cabling a bit and use miniature coax for the Clock 0, Clock 1 and Clock 2 wires between the Raduino and the main board.  These are 30 to 50 MHz signals except for Clock 0 which is the BFO and is around 12 MHz.  Still should use coax as these are the main RF signals that control the rig.  

A better choice might have been to plug the Raduino into the main board and use cabling to connect the Raduino's display header to the display itself.  Could save RFI from the clock signals from getting into things it shouldn't on the main board and also RF from the main board being picked up by those wires.

uBITX on the way !

Graham W
 

Got good news from HF Sigs that my uBITX is on the way.
I ordered Dec 20 -2017 and got the PayPal shipping advice on Feb 11 th.
I originally asked for DHL, but asked to be sent India Post .
DHL is fast, but they want brokerage fees and whatevere else they can
pile on. Whit the post system it may be slow , but the cost for brokerage
and other fees are usually nil..

The HF Sigs team is great! They got a high demand product !

Re: Bitx40 Raduino convert to uBitx Raduino

Michael Shreeve
 

Yet, when I put Ian's 1.01 in it, lsb was lsb, usb was usb. Somehing wasn't perfect from the frequency perspective , possibly the BFO was off. Of course, the software lets you adjust the BFO while operating but I haven't tried that. Still not sure why your original software switched usb with lsb, but soon will figure this out I hope because I would like to be able to switch softwares at will.

The settings do not disappear on the next reboot. This enables the SSH server and then it stays on.

Just an update,
I have incorporated the optional PTT POP fix on the board too as per: https://groups.io/g/BITX20/wiki/UBitx-PTT-POP-Fix

And an extra cap for power filtering...
And extra holes for more power resistors.

Re: phone + ssh/vnc to raspberry pi was Raduino Replacemnt, COMING SOON!

Okay. That wasn’t the method then. Not even sure that’s even an option I was foggy on the details but you create a file called ssh and put it in the boot folder on Sd card. When it finds the file on boot it enables ssh and then deletes file.

Lots of good info on his blog site that should be the first place you should look:
http://www.hamskey.com/2018/02/cat-support-ubitx-firmware-cec-version.html?m=1

It’s like comparing a moped to a corvette ;) fixed a lot of bugs and usability is far superior with his updates. 

Things like controlling the ubitx via your computer via the USB port using  programs like FLdigi and others. He has also made a ubitx manager tool for adding memories and locking down TX on the radio to just the ham bands.. saving your settings and more... it really makes the ubitx shine!

Jack,
 I assume he must have his fixed.  I've got the same error.  I'm running 1.8.5.  I have both the btix40 tab and the si5351.h tab.
I did notice when I installed the si5351 library it put it in:
C:\Users\username\Documents\Arduino\libraries
I even copied the folder to where the IDE libraries are:
C:\Program Files (x86)\Arduino\libraries
and restarted the IDE

 I thought while I was sitting here I'd load the sketch, compile it, and be able to play around with some ideas.   So not critical right now.  Just when you get time.

uBitx LCD Viewing Angle and Replacement Hints Needed

Mike Lichtman
 

Good evening. I have my uBitx mounted in a cabinet that working well with 12w on 75m and 9 on 40m. The only problem is
I went to put it on a shelf on my operating desk and the viewing angle made the display unreadable. While not 
a new to electronics, I am new to playing with digital and lcd displays. Can anyone recommend a plug and play blue/white or black/white display
without the viewing angle concerns that is as close to the current opening size as possible? 73 Mike KF6KXG
