Reprogramming didn't help unfortunately - It's really blown. I know these are sensitive devices and I always take ESD precautions. Nevertheless it became damaged somehow. I never used this input

Is it correct to say that A6 is PTT in the V1.08 sketch , So it should go high when ptt is pressed ? 73 luc ON2AAV

Yes, two others here in KC area have lost inputs A6 or A7 due to static. I think soldering to wire while still connected to the pin is the reason but I’m not sure. New Nano always cured the

Maybe add another button, dedicated to save. ?I use a single button on my Arduino sig-gen to access menus, held in structs-? quite intuitive, but maybe outside the scope of the Raduino .... -- 73

While I was experimenting with digital inputs, I couldn't get pin A6 working. It always reads a "LOW" regardless of the actual input level. The other pins work as expected. I may have blown the

Very cool! I wonder if a opto-isolator out of a junked computer power supply would work... S

Hi William and all, Ithis is a strange problem certainly. I have been following your problem only recently so my comment maybe already reorted. Sorry. Would it be possible to have a sket of the

we can perhaps remove the dc feed path and try coupling thro capacitor. I shall make a sketch and send , you can try that i shall upload soon lee.hemmingsen@...> wrote:

That is not static, static is what you hear on a radio not tuned to a station. Sounds like the cicadas at my farm! This sounds like a wiring error, probably a ground wire mistake between the Raduino

First I really like the newest version, saving the mode is a big plus in my opinion. As long as we are discussing writing frequencies to memory, from my viewpoint I don't see the purpose of writing it

I looked at the output of the Synthesizer today where it enters the Bitx board with a scope and on mine the output went up as the current increased. I didn't measure anything exactly but it appeared

Loud static :-( sounds almost like a smps that's given up the ghost

No other receiver is available :( and the static only gets louder during sweeping no tone. just static and louder static.

Sorry, Allard. I keep forgetting that I'm using a Mega but most are using a Nano...my bad. Jack, W8TEE To: BITX20@groups.io Sent: Thursday, April 27, 2017 5:10 PM Subject: Re: [BITX20]

I heard KC2NUD calling cq shortly after 8pm, he did not hear me. Later I heard KC2NUD talking to W5IFN and hoped to get a relay but W5IFN was in a hurry to go.? Bands were OK, not great. I am trying

Hi, Break up your trouble shooting (Simplify). Dis-Connect Xmit DC Connector and just get receiver going. Dis-connect mic and ptt. Put the speaker connector directly to a speaker or headphones.
