Hi, Just uploaded and still white screen. Ill try compile Reed's code and try that.

Re: compile error

Thanks Joel. I already have the old bootloader selected.

Thanks Reed. I was getting errors as well as warnings but i uninstalled the ide and deleted all directories and folders relating to it and reinstalled. When i uploaded the firmware on previous code with errors screen would not work. I have not tried to upload the new compiled code (with warnings) to the nano as its a V5 i have and ill need to swap the lcd back to the v6 tft and jumper the pins again. Ill try later when i get a chance and get back to you. Thanks to both of you for replying so fast. Reed i will be using your speed increase code as soon as i get the origional v6 firmware working on the v5. Nice work.

Thanks

Well, there is this........  an end-fed multibrand using a trap.

Brian,

It looks like those are warnings, not errors. There are binary starts at the end of that output. Are you unable to upload that code to the nano?

Re: compile error

 

Hi Brian,

Change your processor type to 'Old boot loader' that should let it compile.

Re: compile error

mm0bef@...
 

hi, im getting compile errors on stock V6 code. Im using win10 and arduino ide 1.8.10 .
Its set for the nano and old bootloader as this uploads to the origional nano.
compile Errors.txt file is attached to show the errors.
I dont get any errors on compiling the stock V5 code but i do get errors on the V6 code. Anyone any ideas? Have i got a setting wrong? do i need an earlier version of the ide? Any help is appreciated.

Thanks and 73

All it involves is using a photo quality paper and using a drawing program to create a "faceplate" and then print it on an inkjet printer. Al uses an Xacto knife to trim the TFT display opening. The faceplate is then glue to the mounting surface of the case. We also apply a thin coat of "fixative" (Krylon) to the paper to prevent smudging and protect it from water. Chapter 16 in the book goes into this is greater detail.

Re: TSW Teensy 4.0 to NANO Adapter for the V6 (and software) #ubitx #v6

Jim Sheldon
 

Yes, but you'll have to use different software.  There is a port of Ashhar's 5.1 factory code that will work on V5 Raduinos and the V5 ubitx.  CW may not work on it though and you will have to leave the A6 wire disconnected to keep the 5Volts off of A6 on the Teensy, but since the connections and the pullup resistors/voltage divider network are external to the Raduino on the V5 and earlier (unlike on the V6) just disconnecting the wire to the Digital Plug on the Raduino should be enough.  Our programmer is at a funeral and won't be back until early next week so the 5.1 port still has the old keyer code in it.  It won't work well with 3.3Volts which the Teensy needs.  The ADC doesn't resolve the differences without too many mods and it becomes very sluggish even with the mods using 3V3 to the 4.7k pullup /A6 line.  We haven't had time to work on that yet trying to get a V6 system working first.

Re: New uBITX Ver. 6 Assembled Today

Mick
 

Dave,
Thanks for the feedback and tutorial. I selected that antenna specifically because of the the no tuner claim. Unfortunately I think your snake oil call is on the money! That’s the bad news. The good news is I can build a 40 meter dipole reasonably easily and get on the air at least on one band. That will be another days project.

Re: New uBITX Ver. 6 Assembled Today

Dave New, N8SBE
 

Mick,

An end-fed antenna at it's design frequency (where it is a 1/2 wave say at 7 MHz and thus about 66 feet long) will have a very high impedance at the feed point (one end).  You typically can't just hook it to your antenna jack, and expect to get any power into it.  The MFJ-1984 has a so-called matching transformer (more about that later).

Various end fed feed arrangements are typically used, including 9:1 (or higher) transformers at the feed point.  That may help get the typically 1-2 thousand ohm impedance down to 100-200 ohms or so, which can get it in range of most "antenna tuners".  Also adding a counter-poise ("ground" line) there, to help stop RF from coming back down the outside of the coax shield, which can raise havoc with your rig.  Such a setup almost certainly will require a matching network ("antenna tuner") to match whatever impedance you are seeing from the antenna/transformer arrangement to your coax/transmitter.

End-feds are popular with the QRP crowd, especially for portable operations, because you only need to have a single support (nearby tree) to throw the far end up into.  But care must be exercised in feeding such an antenna, because on the design frequency (and even harmonics) it will be far from the typical 50 ohm output of modern solid-state transmitters.

Now, the MFJ-1984 is making some pretty wild claims for how well their end-fed antenna matches on practically all bands 40-10M WITHOUT A TUNER (WTF?)

I call snake oil.  If it really does show a low SWR across all those bands, it likely has a 50 ohm or similar resistor in the housing across the feedline.  This will of course, give you a nice low SWR everyplace, but it will also dissipate
most of your signal in that resistor, rather than radiating over the air.  There was an infamous shortened dipole that had a center insulator that was potted and shielded, making it difficult to see what was inside, even with X-rays.  Eventually, they were found out that the system had a big 50 ohm resistor in the center insulator housing, and thus, any band looked good, but it radiated very poorly.

You may be able to hear well, in particular on 40M, because the signals on that band are pretty loud, and you can hear OK there with a severely compromised antenna.  But, it will be very frustrating, because most stations will not be able to hear you.  Compound that with running under 10W, and you will be very frustrated, indeed.

Please start with a simple resonant (cut to frequency for that band) dipole antenna, center fed with 50 ohm coax.  You can use a 1:1 CURRENT balun at the feed point, if you want to stop antenna currents from coming back down the shield of the coax, but at the moment, that might considered an unnecessary complication.  Get it up in the air at least 30 feet or so, and try that on your setup.

A simple resonant dipole is VERY efficient, and say if you do this for 40M, you will be pleased with getting out and making contacts (especially on CW for QRP) out to several hundred miles.  At only 30 feet, it won't be a DX champ, because the angle of radiation will be somewhat high, but it will fine for closer in work.

Hope that helps,

73,

-- Dave, N8SBE
