Parts confusion

[VK3XKA]

Hi ... Andy VK3XKA here.

I am in the process of building the Pico Tuner ver 3 and have noticed a couple of resistor conflicts. The parts list and the circuit diagram differ with r4 and r5.There may be other conflicts that I have not yet discovered.
R4 is 2.32k on Parts list and 4k7 Circuit diagram
R5 is 1k on Parts and 1k8 Circuit diagram

Which is correct??? I presume the Parts list (I got from DigiKey) is correct. Maybe the cct drag needs updating?

Both are correct. It is a voltage divider setting the voltage. Maybe I will delete the BOM.

The BOM is very helpful to occasional hobbyists....I'd delete the precision resistor and use the E12 pair, something that said hobbyists may have in a selection pack......but then they wouldn't need to order them.....

That's what I did, but maintaining a BOM is a never ending task. Components go out of stock, part numbers change. Nightmare.

Thanks for doing the BOM …I just received the order as per the BOM …so much easier to use a list and paste it into Digikey …


ordered the digikey order the same day as the BATC order for the pcb and nim …..digikey made it across the Atlantic in 3 days …still waiting for my BATC order to arrive

Digikey is a large corporation with hundreds of paid staff. BATC is run entirely by volunteers, who do everything in their spare time.

Perhaps that’s something to do with it ?

Blimey no sense of humour??? Hence the laughing faces ,…….I honestly give up …people have no sense of humour anymore

Actually Steve it's not about being touchy, Roger was just saying the way it is

And yes occasionally I do get just a little bit peeved when people imply the service is not up to scratch as several of us spend many hours a week keeping BATC running for the members - I'll be going to the post office today with a bunch of orders which I've just put together.

Hi Noel
I am sure the majority of members realise it’s a voluntary service …but obviously there’s a few that don’t ……anyway still waiting for my order so hurry up down the post office ……
