Yes, that is a good reason to use a dedicated PC, Linux machine or Raspberry Pi type machine to be the computer running your station. And put the least amount of software applications as you can on the machine. Certainly don't use that machine to do your banking or store your Bitcoin wallet :)

If your computer controlling the station can accept incoming connections from the internet (You can connect to it and log in for your remote computer directly) you need to try to keep your computer up to date with security patches, as well as choose software where the developers currently maintain the software and keep up with what is going on in the security/exploit arena. For open source projects you can generally check how recently the last code commits were and if bug reports regarding security issues have been addressed. 

If you connect to your computer running the station through a third party website, and the station and remote access computers only make outbound connections, the security issues can be less. However, it that case you are somewhat at the mercy of whether the third party site was designed by true technical experts or just business people seeing a market to build a business around and not understanding (aware or care about) the nuances of what they are having built for them.

-- Tangent warning -- Of course you can go overboard. Not every little exploit discovered is a real threat. Risk has to be weighed with the possible damage. I worked for a company when they went into the first phase of evaluating/addressing security aspects of their internet service (good!) they went into full blown paranoia and the security people reacted to every exploit they read about on security sites without reason. Had a new set of servers provisioned for a project and just about the only way they would sign off the systems, was if only the operating system without the custom software that made our business a business, was installed on the machines. And, no, our custom software was not faulty from a security perspective. Reason on both sides prevailed eventually.  -- End of tangent --

Not bad at all! What kind of audio amp did you use? We were at a farm yesterday and I carried a KX3 with a longnwire. It was hopeless. I couldn't get the vswr below 4 and the band was dead. No contact made.

hahahaha!  You're right!  I hadn't noticed that.  I'm no programmer, I'm just someone learning / bumbling their way through.  I did my best to merge Bruce Hall's amazing improvments into my own minor changes, and I apparently missed that / screwed that up!  I'll look into it shortly and see if I can figure out how to fix it.

I am working on a masters of cyber security, I just wanted to speak up about the potential security issues. I like team viewer because by default it generates random passwords. This obviously won’t work here, so it’s important to make a password or passphrase at least 14 characters long. I also wouldn’t store personal or sensitive information on the pc. You are opening a door for hackers to use your station etc.

  Richard, I wish that I could say that I can still do most things.
 But alas, my COPD and things have prevented that.
 So I am limited as to what I can do physically.
 Can still solder and troubleshoot, plus what does not require lifting more that 10 pounds or so.
I amused to carrying about 8 pounds on my back (O2 tank in backpack).
 Though that sometimes makes it harder for me to get back up.
 More power for those of you who can help persons like myself that are now limited by a combination of things
  No, I'm not asking for help for myself, other than what I mention on my facebook page.
 One thing I will be able to help with is programming memories for certain GE radios

Re: Remote access - I want to connect ubitx to Raspberry PI and remote in #remoteaccess

i used TeamView for free with personal use. I took a bit to get both computers trusted and set up...one with Ubuntu/AtomicPi and the other Win10/oldlaptop. But...it works. Here is a screen cap from my win10 laptop controlling the AtomicPi with ubuntu controlling my V4 uBITX running WSJTX and completing a JT8 QSO.

I am thrilled!!! I have remote control for both good and evil...hahaah (actually not evil as I don't really know what that would amount to, hahah).

After this success, I switched to Fldigi and that works as well sending the keyboard via the link to Fldigi text input window. However. If the uBITX audio output level is set too low from the last time I physically adjusted the speaker volume, then I have no way to change/increase the uBITX output level to make Fldigi happy.  I'll pay with setting the uBITX output on the high side, and then try to lower the level on the software side of some application.

Now I see the real advantage to complete visualization of the transceiver (.e.g. Flex). if I had all of the uBITX functions on the screen, then the volume controls would be screen sliders allowing me to adjust it all from remote control. 

So question...is there a way to adjust the uBITX volume levels in software through some interface?  

The other challenge is not seeing the RF output levels. At the rig, I run the uBITX RF output through a old fashioned power meter to keep the lid on power levels. It would be nice to see the rig output on the screen somehow. I know I can adjust the drive level remotely, I don't really know the impact that is having on RF power output levels...

But, to the question of basic remote control, assuming your physical rig i/o levels are set in the range, then TeamViewer will allow remote control of your computer apps and rig. Seems to work fine. 

If there is a reboot, I don't yet know about having TV boot automatically so you can always get remote into it. I'm sure that is doable.

I need some help trouble shooting bitx 20 ver 3b mixer stage. The VFO p-p is 125mv (In fact I had to add a capacitor to the frequency counter for it to work)) Q7 dc voltage is per the manual , when I scope Q7 output after connecting the mixer I get 4.1V sinus clipped at the top by the 12V power supply . I attach a picture of the scope. Any advise ? I forgot to mention that this is unbuilt kit and I just got to the mixer stage per the manual.

With this updated firmware and a jumper I am still seeing -13dB in SNA mode? Is this still considered normal? I also see some un-linearity with some pads but ill blame that on lack of calibration for my unit.

Re: Is there Nextion 5" firmware for Basic LCD NOT Enhanced?

I put not a basic and enhanced version of the 5” screen in the file section. Look under the directory AJ6CU. 

I do not have a basic version so I was not able to test it.  The enhanced  version has a faster processor so I would not be surprised if there are some performance issues. 

Let me me know how it goes.

Re: Antuino 2.0

WoodJRx@...
 

I've attached to hex files (compiled binaries).  I'd recommend trying mine (ported to OpenGLCD, added bhall66's linearity and encoder fixes), and doing calibration afterwards.  I'm quite happy with my devices accuracy and functionality, particularly with those improvements.  If that doesn't work to improve things, i've also included a compiled binary of the original code from Farhan.  That will return it to the way you received it.  With the hex files you just have to worry about setting up the Arduino IDE to connect - you don't have to worry about libraries, compiling, etc.  (IDE settings - Board:  Arduino Nano; Processor: ATMega328P (Old Bootloader); Port:  Whatever it is on your system)

Mine seems just as accurate as any other equipment I have here (which is admittedly nothing even remotely near lab grade).  YMMV. Let me know how it goes!

Farhan,

So, what’s the answer? Does the AD8307 need to be changed? This does not seem to be necessary as my readings are pretty consistent, just inaccurate. Would Arduino firmware programming changes fix it? If so, I don’t think that is something I have equipment or expertise to do although I may have club members who could.
