Re: uBITx Control circuit...
Bill,
Did you create a PCB for this, or should I just go ahead and do one for myself?

Just a heads up. Do NOT use the battery pack and have any power in the DC jack. You will have a melt down.

Forgot all about it.? But didn't use it much when it was first started.? I backed it up a number of times but that was it.? Don't think I even automated that.

About 2 years ago I thought it would be useful to have a map where BITX owners could pin their location.? In that time we¡¯ve had over 450 users added to the map.? Shortly after setting up the map in google maps I registered? which redirects to the map page.? The domain name is coming up for renewal and it got me thinking.? Is anyone using the map?? It shows over 26k views but most of that was in the beginning.? I don¡¯t mind renewing the domain name for another year but I¡¯d like to think someone actually visits the map every now and then.

Re: Antuino battery voltage
There is a problem on the DC jack. The assembly girls couldn't get the DC jack onto the pcb, so, they, er, drilled a bigger hole and destroyed the PTH. There is no connection between bottom and top tracks of one of the DC jack pins. Take an iron and flow as much solder as you can on the top layer of the PCB so that it catches the tab on the top and spills over the mounting tab (on the top tracks). Here is picture of which tab is the problem

I was in error.? Rechecked the battery voltage tonight and it is 9.45 v with the new batteries.? I thought it had only 4 AA batteries in the internal battery holder but on second look there are 6 AA batteries.??
Still won't work from the battery pack.? Does work using the external power jack and 9 v battery.??
Will have to take more time and look into it.

Re: Raduino frozen on BITX40
Perhaps hf signals can send a raduino cheaper. Try once , before landing on an 30$ item.

Connecting IK3OIL FLL VFO reader
Can anyone tell me where on BITX40 board can I connect IK3OIL FLL counter? I am thinking of reconstructing original analog VFO and I happened to already have this FLL counter in a drawer. It is not a simple reader but should keep VFO frequency to stay stabilized against the drift, so I suppose it is not to be connected only as frequency reader to IF stage or it is? And where?
I am doing this because my Raduino has toasted (probably Si5351 chip).
Thanks for any help..

Good news Sasha.?
I have the same loop controller parts here, just waiting to be assembled. Please share a short summary on what was needed to get this to play with the uBitx.

So I finally did some testing and it really seems as everything works as it should.
Thanks everybody for your help with the project, I could not have done it without you.
Especially you John - your help and insight was awesome and I am deeply in your debt.
Thanks also Jack (had wanted to thank you before, but forgot) for your explanations of C.
I'll guess I am getting a book now to dig myself a little bit deeper in programming.

Re: Antuino - the antenna analyzer

I slapped one together on the bench and used 69mhz filters salvaged out of a really dead?
TS830 instead of the crystals for the filters.? Tweaked the code and works well.
Could you explain a little how to modify the code for other IF is just one or two lines of code or mayor surgery.
Thanks in advance?

Thanks for the modified glcd LIB.?? It works fine on my mock-up here.? I found an unknown controller type display and it worked straight away.
As a pretty raw beginner, my efforts with using openGLCD were slow!
