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.?

Re: Raduino Replacemnt, COMING SOON!
Just an update, I have incorporated the optional PTT POP fix on the board too as per: /g/BITX20/wiki/UBitx-PTT-POP-Fix
And an extra cap for power filtering... And extra holes for more power resistors.

I¡¯m such a nubee I am still waiting on shipment of my uBitx.? But what is the difference between the KD8CEC firmware when compared to the stock firmware that comes with the uBitx?? ? 73-Gary ?

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.

Joe KD2NFC? I figured it was time to free this thread from VK4PLN's post.
There is another option if you can beg, borrow or otherwise obtain a computer for the very first set up.? Frustratingly SSH is disabled on most of the pi distros by default so you will need another box to set this up with a card reader/writer.? Also if you are using a windows machine you need a way to write linux files.? I used a demo version of Paragon ExtFS ? Once done you can SSH or VNC (for gui) into your pi via wifi using your phone or tablet as a monitor.? I fumble around with the phone screen keyboard for minor stuff and use VNC or PuTTY on my desktop for real work.? I don't see why you couldn't use a bluetooth or usb/otg keyboard connected to your phone.? This is a good article to get you started I currently have 3 pis running with this set up.? If you go this route you don't need all the USB ports on the Pi3 and can go with the cheaper ZeroW.? Just make sure you get the W with wifi not the plain zero.

Re: Bitx40 Raduino convert to uBitx Raduino
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. ?

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 !

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.

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.

Another error on the Wiring UP diagrams (all of them) show the CW Key connected to pin 2 of the key jack. ?Pin 2 is the RING terminal, not the TIP. ?It is customary to connect a straight key's contacts between the tip and shell of the plug and the paddles
normally (but not always) have the DOT paddle connected to the TIP and the DASH paddle connected to the RING terminals of the appropriate key jack. ?
This has been mentioned MANY times by myself and others and needs to be changed so the newer people building the uBITX have the right information rather than wiring their rigs up wrong and having to change them later when they find out CW doesn't work.
