When you are in the Arduino IDE and uploading the sketch, can you see the TX/RX LED's flashing during the upload? What message(s) do you see issued by the IDE. If the Nano is powered by the USB cable,

Minor but rather important detail, my kit arrived with the two ep connectors, but one of them was missing the knurled nut. What would you call those connectors, besides EP connectors, in order to buy

My Bitxv4 came in on 3/7 C107 is in there. My Bitx40 hasn't workered yet. Just audio noise. Display all 16 character positions are black. I also recv'd the mystery SMD cap. Did get the 0.1 for the

Thanks for the information! So why are you not happy with the outcome?

Jerry, My earlier posts relate to strong 7.2-7.5 Am stations leaking in because of the 4xVFO harmonic mixing in with 12Mhz IF. The probe is on the output of the VFO at the mixer toroid: T2 Same path

It does take some time. It can take up to five weeks. Patience. The tracking info is of little help, too. Mine still shows at the airport in india, yet was delivered a week ago or so. Alan Whitman

Alan This is the data that I have been collecting. Randy BITX40 Deliveries – Randy, K7AGE 3/15/17 Farhan says: Number is like this :AB-xyz The xyz is the serial number within the batch B. A

Go to?http://www.hfsigs.com/bitx40v3_wireup.html ( http://www.hfsigs.com/bitx40v3_wireup.html ) The photo at the end of the section "Step 4: Volume Control" is correct, follow that example.

I ordered a BITX40 on 24 Jan and received a notice that it had been shipped on 30 Jan. ?I live in Washington State, USA and have not received it. ?Can anyone advise if this is consistent with what

Would help if you could tell us exactly where you are probing, if this is transmit or receive, what signals are present. ?Maybe include a description of what you see on the spectrum analyzer. ?I

Curious. ?I bought two boards. ?The one shipped end of Dec had a missing C107, looked like it had been chipped out of there without disturbing the solder on the pads. ?The one shipped end of Jan

Hi majcool Just to make shure Try analog tuning 1) disconnect the DDS1 connector 2) install L4 3) install a 10k potentiometer on the TUNNING1 conector and see if the receiver works. I believe that

No. ?The 1mhz problem is not due to bad Nano firmware. ?Not a bad 5v or 3.3v rail. ?There's no way for a reference clock to go from Nano to Si5351, so it's nothing to do with the 125khz startup

It is never a good idea to parallel two supplies of different voltages. You may get away with it 999 times out of a 1000…. But! Fred W4JLE Sent: Wednesday, March 15, 2017 1:12 AM To:

Hi Jack, I read your comments about arduino Nano. Have you downloaded the Nano as installed on the BITX40v3? I tried to download the simple Blink sketch and it failed. My question is with the Nano

Hi Mike, You may also want to look at www.tronixstuff.com they have a series of tutorials that are very helpful. 73 Elia, M0ZHN

My preference is for these two books, available on

I second Jack's comments. I'm using clone Nanos for several projects in development and I've never had any issues programming with USB while they were in circuit, with another power source attached

If you don't mind waiting for China post, look here: http://www.buydisplay.com/default/character-display/16x2-character Lots of options and cheap. I have a few of each color. Just in case...
