I will but it might be a few days before the BITX is wired and tested.

Re: uBITX No Power Output all of a sudden
#ubitx
I suspect poor plating. Rig had been working just fine and I had power out set to 5 watts into a Microwave Associates 20 watt dummy load on my YouKits DP-1 digital wattmeter on 40 meters. I checked the resistance on two of the other V3 uBITX boards I have and it varies slightly as you press on the board with an insulated tool near that VIA.
Don't know about the V4 boards, but during any V3 build, I'd suggest running a piece of 30 gauge wire wrap wire through that hole and soldering it on both sides as a precaution before mounting the board. You will probably have to carefully scrape the solder mask from both top and bottom of the VIA pad. I'll try and take and post a good hi resolution photo of it later in the day so you can positively identify the spot. Jim - W0EB

Whatever, Raj, I recommend soldering a bit of 30 gauge wire wrap wire through the VIA on both sides at least as a precaution.

Thanks Bjorn, for the link... That was the issue. Once I loaded that file, things look much better!

Re: Windows Serial Port Problem
Jim Lommel <wd8rwi@...>
I was completely wrong about there being a download manager for Win 10. Microsoft has changed to a service model from a subscription model and now you have no control over what updates get installed and what don't get installed other than not be connected to the internet. My understanding it that this was done so all extant Win 10 installations are the same instead of there being millions of different installations. Does anyone else have information about how MS is

Hi

I almost completely abandoned MS and Windows long ago. I have one legal copy of XP that I run in a virtual machine in Lunux if I run it at all. It does not get exposed to the internet. Reading this thread I have dug my trench even deeper and fortified the walls :) Yes..there are a few things that I can't run without MS Windows. Life without those few things is not really so bad :) You put your money down and you take your choice. 73, Bill KU8H

Thank you. That's where I tried to find it. Under the "Circuit Description" tab under bitx40, there is a link part way down the page for downloading the schematics. The link takes you to
http://www.hfsigs.com/bitx_with_raduino.zip which is not found. If anyone has the correct liml, please let me know.

Well if one goes out of his way to check an error condition and finds it you should at least let the user know! Probably should write the substituted value into the EEPROM. rOn

Nextion and the Icom7300

Bo Barry <bobarr@...>
Completely off topic, almost. But this is where our genius Dr Ian hangs out.
As we are learning, the Nextion is a computer all by itself! I saw a YouTube by YO2? where he had his helping the awesome Icom7300 along! I'm slowly learning from Ian's work and will put that project on my list. Gotta do the RTTY contest at 2pm Eastern today first! 73, Bo W4GHV since '54

Re: Source for female connectors/pins/manual crimp tool?
Jon Titus, KZ1G <tituskz1g@...>
Radio-control aircraft enthusiasts use the same types of crimp connectors, so a local hobby store probably has male and female pins and a crimper. The crimp tool linked to below should do the job and it won't kill your ham-project budget.
https://www.showmecables.com/d-sub-crimp-tool?gclid=CjwKCAjws8vaBRBFEiwAQfhs-BmOdBAvHw7fnPZd1Wnhm2dWCRCMJ8UI-yR39lF6crX_4uVqluOTJRoCSFcQAvD_BwE I used a similar tool for my uBITX project. For female crimp connectors that attach to 0.025" square posts on 0.10" centers, use the Jameco Electronics part #100766. The small tabs crimp the metal wire, while the larger tabs crimp the outer insulation and provide a strong physical hold in case you pull too hard on a wire. Jameco also sells the connector housings for from 2 to 36 contacts. -- Jon Titus, KZ1G Herriman, UT USA

AGC manual rf gain versus KD8CEC ATT rf gain software
Gary Hanson
While waiting for my Nextion display to arrive, I completed the AGC kit and was considering whether to add the manual RF gain as suggested by Don, ND6T. I also plan to upload the KD8CEC firmware and noted it has the ATT software RF gain control. Am I right to assume that I do not need to do both?
The manual Rf gain limits the signal at the front end and the ATT software shifts the signal in the filter. Any advantage of one over the other? If they both accomplish the same goal, then it comes down to twisting a variable pot knob versus using a touch screen slider. Gary Hanson, KJ5VW

Re: AGC manual rf gain versus KD8CEC ATT rf gain software

Gary, after listening with AGC does it seem you still need manual RF gain control? I'm happy with AGC only. I would recommend the S meter connection off the AGC board and KD8CEC software though.
