I ordered two Bitx40 over the weekend?and had delivery by?DHL.? They were here this morning.? I have ordered a lot of things in the past, even overnight, it was as fast as anyone could hope for.?

*Thanks* Allard, PE1NWL. OK all, Yes because my situation is still in experiment ballkack. So the perfect grounding and casing to avoid the stray capacity will be good. ja9mat Hidehiko.

Yes thats it, take the red wire from the 3 way socket and connect it to the input, output from AGC then goes to AF pot. Think thats part of the fun, most is words from e-mails, bits of info from the

i will use the heat shrink once its in the box and wired up ( after i show it flashing away and working). where abouts did you connect yours too. do i take the audio from the board where the volume

I used a piece of heat shrink tubing over the LED/LDR, so its nicely confined and the LDR only sees the flashing of the LED, Level of flash is only low, although I think it depends on the LDR and the

so here it is Phil one board nearly finished. Thank you for your assistance. i haven't fitted the audio 10k trim pot i will need to shop around or hunt in the depths of a junk box for that part. i

Terry, With the latest SW version 1.14.1 doing CW is a no brainer. The hacks needed for it are very simple. Take a look before you waste the BitX resources with a seperate TX. PJH, N7PXY

Very nice, thanks! ?I might even be able to remember that when using some other computer. Oh, and nice to see that representation from Flora OR still outdoes the entire Portland metropolitan area.

This could be automated with a Perl script running in a cron job. The www::mechanize::firefox module supports, among many other functions, the automation of clicking around on a web page.

Glad I could help. Look forward to your finished results Phil - G7BZD

OK, now I have checked the ATmega328P documentation. The digital IO pins have a pull-up only, guaranteed to be between 30k and 60k, which can be disabled. The ATmega328P does not have an option to

Allard: I think I'd add a pulldown resistor somehow, make the behavior vaguely defined. As you have found, there are significant differences between rigs on how fast that charge leaks away. Using the

Allard: I'd give this a try. Jack, W8TEE To: [email protected] Sent: Wednesday, June 14, 2017 1:09 PM Subject: Re: [BITX20] CW Offset does NOT work on Raduino_v1.14.1 for BITX40 Hmm, yes you may be

Funny you should ask.. As I was reading Jack's post I was thinking, it's an analog line, use it like one. Vince.

Hmm, yes you may be right that in some cases the 7805 output hasn't dropped sufficiently to represent a digital LOW. Another way to circumvent this situation might be to define A0 as an analog input

I must have misunderstood. If the internal pull-up resistors on a pin are activated, doesn't that impact the voltage seen on the pin? Also, if the code does a digitalRead(), the documentation says it

That's another option. I already have right channel PTT circuit in the form of the Fldigi CW keying circuit. I was wondering if I will incorporate it. The final design is still floating around in my

The code is doing a digitalRead(PTT_SENSE), I'd expect the threshold on the nano to be somewhere between 1 and 2 volts The problem is that when the +12v TX line into the LM78L05 at U3 goes to zero

Given your code, Allard, I'm surprised he needs a dropping resistor on that line. Jack, W8TEE To: [email protected] Sent: Wednesday, June 14, 2017 10:51 AM Subject: Re: [BITX20] CW Offset does NOT work

Hi Hidehiko-san Yes you could be right. Another possible cause could be poor grounding of BITX main board and Raduino board. If Raduino board is not grounded perfectly, some small potential difference
