Thanks Jerry. I had read about the issue and took particular care not to connect the Nano when the soldering was done. It was hooked up last. I will check the Voltage into the Nano and report back 73

Those pins out of the Nano are rather dainty, could have blown the Nano's IO cell if you soldered it to the pot while the wiring harness was connected to the Nano and the soldering iron wasn't quite

Hi all Finally got around?finishing my BITX40 Ver3?yesterday. It passed the smoke test. Eveything seems to be OK except for the tuning. It is locked on 6.9MHz. I am using a 10T, 100K precision pot

And one more thought: Bryan, did you perhaps install an NPN bypass transistor across the PTT switch for CW? If you did, did you connect it correctly? If installed incorrecty (reversed emitter and

Another thought: Try without the PTT or mic plugged. The relay release voltage is 1.5 and coil is 450 Ohms. So even a 2K across the PTT line will prevent the relays from releasing. You could check the

I once had problems with one of the relays and replaced it by: brand: ZETTLER type: AZ822-2C-12DE

OK Bryan, so far out of 1000's sold I read yours the first relay complaint. Only keep in mind that the standard relay numbering of OMRON and others is different from the BITX40 numbering. OMRON coil

No they are not Omron they are some obscure brand , can hardy read the writing Contacts not made in receive position Bryan vk7kwb Sent from my iPad

What are those connectors called, We use HE14 connectors at work, but they are different, could do with a set. Phil - G7BZD

The standard BITX40 board doesn't come with a connector for those pins. I just soldered the wires directly to the board. But of course you could install a connector for those pins if you want to. 73

Thats right, thru plated holes to the one side of the 5 way connector. Phil - G7BZD terryhugheskirkcudbright@...> wrote:

hi the picture appears to show D5, D6, D7 connected directly to the board without a white connector. Is that right Terry GM4DSO

That is one nice element of Shuttle Tuning, just a turn either way and it starts to scan. Speed determined by how far you turn. de ND6T

* Have had DHL perform tax collection on goods delivered here in Israel before. Avoid them like the plague, snail mail usually VAT free for anything $75 dollars or less. Still waiting for my BIT40X

Not only did they had masks, also a double barrel over under pointed at me for 35 Euro ;)

Would also like a scan feature, could it be done from separate UP & DOWN buttons. I know that may be a bit more involved, or not ? Just happen to use a microphone that has UP & DOWN buttons. Also is

Does your board have OMRON relays? Mine has some other brand. The PIN numbers of the relays is based on a 16 pin IC socket. So it is 1- 3- 5 --8 16-14-12--9

Sad to hear that Bryan hope it you work it out. Regards Kevin Norris VK7HKN

Dear BITX owners Just built BITX40 kit all went ok some squark on speaker when turning audio down , and PPT noise . but my gripe is the fake OMRON relays both failed on receive ( no contact from fixed

Hi all I recently bought the Raduino upgrade kit. I don’t know what version software is on it but it chugs as I turn the turn the tuning dial – chug, chug, chug Does the latest software fix this
