Im sure this has been cover in a previous post but i could not find the same symptoms. I accidentally shorted the heat sink on the irf510. I had no power out at all after that. Power from PA is 12v, i

I am running on battery power and I have clicks.

So it took me this long to test the IRF510 per your suggestion Jerry. To recap, when I first turned on my BITX20 there was a snap pop and a flash around the IRF510 (not sure exactly where.) Receive

The 72 Ω impedance only applies in free space which an antenna is not unless it is more than 1λ high. That means 40 metres on 7 MHz. I wonder how many amateurs can put an antenna that high on 7

Thanks John, Your observation of NO CLICKS with a battery is interesting balance we have to analyse and find means to balance. I would like to propose a filter on both positive and negative leads

Not sure if this helps anyone else but I had been running my Bitx40 from a small 350 watt computer power supply I have converted over to a bench supply for 12, 5, and 3.3 volt power. I had never

Part of the problem is that there are multiple libraries using that same name and not all function the same way. If you Google "Arduino LCD library download" you'll quickly discover LCD libraries from

#include <LiquidCrystal.h> Its called LiquidCrystal. It's available through the library manager. 73 - Ben [email protected]> wrote:

It works petty well for me it's a lil slow but works. I think it was worth the build.

Yes the same way connected .But results are not good for ssb phones .But cw working good. wrote:

Hi Henning, it's the standard Adafruit LCD library, version 1.0.5 installed in my IDE. What compilation error do you get ?

does not compile due to an error of the adafruit LCD lib, so whichn lib is used in Your compilation? Henning Weddig DK5LV Am 15.04.2017 um 20:03 schrieb Andrew Whaley:

I just tried to compile, but I get an edrror, the Adafruit LCD library seems to be the wrong one as thsi lib is on error. So which correct LCD lib is used? Henning Weddig DK5LV Am 16.04.2017 um

OM Vu2RJW Please let me know if its effective on Farhan's bitx 40 Also did you take audio in from Pin 1 (Red wire )of volume pot by connecting it directly to AGC and? audio out to Pin 1 of Volume

Thanks! Once I figured out how to load the libraries in the Arduino IDE it works. John/N6VTS John Higgins 719-330-0916

Yes! Thank you! John/N6VTS John Higgins 719-330-0916

Thanks Andrew...I'm working on getting the "libraries" in the right location in the Arduino IDE. Will report when I "crack the code"..hi hi! 73, John/N6VTS John
