Ubitx and 60 meters Walter Robard Seiler <waltrseiler@...> #41878 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 Walt VE7CWS

Re: Ubitx and 60 meters M Garza <mgarza896@...> #41879 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@...> #41880 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. 73 Dave KD1NA

Re: My uBITX is alive!! Jim Sheldon #41881 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 #41883 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 ! VE3WGW -73-

Re: Bitx40 Raduino convert to uBitx Raduino Michael Shreeve #41889 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.

Re: Raduino Replacemnt, COMING SOON! Nick VK4PP #41892 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! Joe Puma #41893 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. https://www.raspberrypi.org/blog/a-security-update-for-raspbian-pixel/ Joe toggle quoted messageShow quoted text On Feb 14, 2018, at 5:41 PM, Fred Buecker <tfbiii2002@...> wrote: The settings do not disappear on the next reboot.

Re: My uBITX is alive!! bill richardson #41894 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! toggle quoted messageShow quoted text On Feb 14, 2018, at 6:29 PM, Gary Shriver <gshriver@...> wrote: I’m such a nubee I am still waiting on shipment of my uBitx.

uBitx LCD Viewing Angle and Replacement Hints Needed Mike Lichtman #41898 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
