Do your files include the .drl file? ? That¡¯s usually the hangup for me. From dip trace you have to do a second export to get that file ? ?Without it they won¡¯t make the printed circuit.?

I've been trying to get a PCB from Peter's Gerber files, I'm assuming a 6x6in PCB - but the Gerber files are unreadable by the company I paid... I'm presuming a version error in the Gerber files. Anyone have ideas for free software that can import a Gerber
file?
I'd hate to start from scratch - knowing that others have already done the work - but it may come to that...? I'm not experienced in creating PCB's...

If you installed the IDE correctly, you should have the arduino.H header file in the IDE's root directory below:
??? hardware\arduino\avr\cores\arduino\Arduino.h
Also note that C is a case-sensitive language, so arduino.h is not the same as Arduino.h. Your statement shows lower case which may not work. (I think I saw somewhere there is an arduino.h, but I'm not sure.)

Thanks for the tip on desoldering with a wick atouk i was wondering why desoldering didn't work well. Forgot that manufacturers are lead shy.

Re: Ubitx V3 Please Help, ANTENNA Pins on PCB have SHORTED no Receive
#ubitx
#ubitx-help
Fabian you will always get a DC short across the antenna terminals. If you follow the circuit from the two antenna connectors one is earth, on receive the other goes from K3 contact 12 to 14 to K1 contact 12 to 14 to L1, L2, L3, L4 of the Low Pass Filter to T2 winding one side marked number 1 through the coil marked side number 6 to earth. On Transmit the winding of the output transformer T11 marked number 2 is earth, the other side of the winding marked number 6 goes to KT1 contact 12 to contact 16 and then through the respective Low Pass Filter depending on which band you are transmitting.
As you can see there is always continuity through the various coils and you will always get a DC short across the antenna terminals both on receiving and transmitting.
As for not receiving anything, did you connect an antenna to the transceiver?
Regards Lawrence
Hello,?
?
My Name is Fabian and 31 years old from Meiningen in Germany and a have HAM Licence Class E since 5 Weeks and my English is not the best so i hope you can forgive me my writing and spelling mistakes and can unterstand my problem. I need really your help and i i really thankfully for any help so i can cry when my Ubitx receive at one day..
?
I have not much money and a have many health problems so a have only a little job and can't buy a Transceiver like a Yaesu or Icom in this price class.. My big Dream was to have a little SSB Transceiver for 80m and 10m, bescause in Germany with my HAM Class E onky 160m,80m,15m,10m are allowed.?
?
So a other HAM from my town sell a Ubitx and i was very lucky to think for 130€ my big Dream was come true.. He says its the best for me and not really difficult to construct, only little bit of soldering an than i can have my QSO a few our later.. So i trust him because i think its a friend, but he knows that i was a beginner of HAM.. I do not want to blame him, only I am a bit out of tune because many said a kit was not for a bloody beginner.?
?
But now to my problem..
?
I have been trying to get the transceiver running for a month but unfortunately without success. I have tried many things including the updates of the CEC versions and the Ubitx version v4 but all you hear are rushing and sounding like digital beeping. I've also tried the audio NF chip, the TDA2822 is the version FCI and does not seem to be the problem. Then I tried everything again with other antennas and also outside to avoid disturbances of the house. but again no success.
?
By chance, I then checked everything for short circuits and suddenly I see with the continuity tester, the multimeter tester, between the 2 pins on the board where you connect the antenna cable, which has a short circuit just these two !!! I did not know any further .. Then I was in the Ubitx chat from the forum here and David said that's just not good and that must be the error that I'm not receiving properly .. By the way, thanks again to david if you read it, You are really nice and I would like to say thank you again !!
?
that's exactly my big problem. I need urgently your help to repair the antenna pin short circuit. I'm really really thankful for any help I can do now or check something. or if it is possible that you had this error before and know what needs to be repaired. I am really very sad to have not had a single QSO for my test for ham... but maybe everything will be alright, I always hope so...

I say thank you very much!

Re: Ubitx V3 Please Help, ANTENNA Pins on PCB have SHORTED no Receive

Hello Fabian,
If you trace the circuit from the antenna it will lead you through several relay contacts to an inductor to ground. That is a piece of wire that wraps around and around with or without a core. Your meter uses direct current to measure resistance and continuity. Direct current sees any inductor as a plain old piece of wire - a short. So it sees that inductor to ground as a dead short. At RF frequencies however, it is NOT a short. Most - maybe all - radios will have this:) So you should continue looking elsewhere for the problem.
Have you completed the "alignment" steps? If the oscillators are far off frequency the radio will not work very well if at all. Do you have a more experienced ham there who can help you?
Fabian, we all have or had different 'starting' places. It is not reasonable to assert that a kit is not for a beginner! At one time if hams did not make their own radios from scratch (not even a kit) they had no radio at all. The uBitx is not really so much of a kit. Building your own gear from scratch or from a kit is 'learning by total immersion'. Sometimes that method can seem frustrating but eventually we all get where we want to be. Just relax and enjoy the 'journey'. After you have finally sorted out the trouble and corrected it you will find it more satisfying than that Kenwood or Yaesu:) Those have their own rewards and can be an appropriate starting place for somebody else.
I started out building radios from a pile of old junk harvested from dead radios. At times it was discouraging but in the end it doesn't seem to have hurt me:)
And now about your English. Your English is very usable for a non native English user. I know only a few German words and not very much about the grammar or syntax. If I was suddenly transplanted to Germany I would experience 'total immersion' and would soon be speaking, reading, and writing German. It would sometimes seem frustrating but eventually I would fit right in :) For now your English is substantially better than my German.
73,
Bill KU8H

Fabian:
If you look at he schematic, you will see that the antenna connects to T2 through the relays and a Low pass filter. It should present a DC short. However for RF this is OK since the transformer is normally not a short. If you could describe your problem in more detail maybe we can help you. Does your Raduino work? Do you hear any signals? Etc.

Re: New version of TFT Touchscreen based VFO-BFO for uBitx
Costs vary greatly with larger displays. One reason is because many of the less expensive color displays push the display processing onto the main processor while others use the hardware on the board. Also, many displays either do not support touch screens or there are no third-party libraries for them. Some displays have less resolution than others.
The display we are using in our forthcoming JackAl board comes in either 5" ($34) or 7" ($44) size, uses the RS8875 via SPI, has 800x480 resolution, and uses capacitive touch:  By pairing it up with the Teensy 3.6 ?C with 1Mb of flash, 256Kb of SRAM, and clocked at 180MHz, we can do DSP that many other processors cannot. (The photo shows the SSB in GREEN and its choices of filters have selectable bandwidths of 1500, 1800, 2200 (selected), 3000, and a user-defined custom (Cust) bandwidth.) We also provide about a dozen free !/O pins to play with.
Our board will likely cost more ($30) than a Nextion display system, but we think its features and horsepower will bring a lot to the table.
Jack, W8TEE

Re: Fried irf510s replaced but
IF more watts on 20 than 40 either a relay is stuck or like a friend had the coils for
the 40M filter were plain wrong or got damaged from handling.
relay or coils or the associated caps for the coils.
L17, L18, L19 should have 14 turns(a turn is though the hole once), the bad radio
