do you every visit bitxmap.com?
#poll
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

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..

Looking at my board it looks like an incorrect footprint was used for the barrel connector so some holes were drilled out to make it fit. The concequence was that one of the holes all all the through hole copper removed. Thusly there is no electrical connection from the bottom to the top of the board.
Putting solder on the top of the pad to the barrel connector fixes this.

I forgot because the Most of the value of WSPR Calibration is the same as the value of Master Calibration.

Hi Ian,
this bug found by Carlos is still unfixed, correct?
I am using version 1.11 of the uBITX-Manager (and I have not seen a newer version yet) and can still confirm the behaviour.
The once entered WSPR calibration value can never be read out again - there is always the master calibration value in the corresponding field.
I just played around with the WSPR Calibration to improve my setup - the built-in WSPR funxction really is a great feature.

I took a few more measurements, adding in 3dB and 6dB steps at higher attenuation values.? It looks like the additional 3dB and 6dB steps are attenuating RF appropriately.? But the shape of the graph remains non-linear.? ?See attached.? ?
I am not sure what to try at this point; any suggestions?

One way to know is to measure readings of smaller attenuations at different attenuations. For instance how does the readings change between -50db and -53db as opposed to -10 and -13 db? My tests show quite linear relationship between actual attenation and db readings.

What i think it should be is to have all the Fonts in a directory called "fonts". Fonts.h is just a list of the fonts used in the Sketch.
in the same directory as the sketch.
then change #include <fonts/allFonts.h> to "fonts/allFonts.h"?? so when you run the sketch in the IDE, it gets the fonts from the sub directory /fonts
