Re: Handedness of winding doesn't matter?

There is no right way. Either way is okay.

Why not just rewind the right way?

Re: Handedness of winding doesn't matter?

In your application it should make no difference. It's when you are winding a two or more winding transformer that it becomes a problem as the wires won't come off the core in the proper arrangement. Electrically it makes no difference. In other words the physical layout for the board holes is what matters. Electrically there would be no difference. Lee, w0vt

Handedness of winding doesn't matter?
Adrian Boyko
Hi, I just wound this with the opposite handedness of the example in the build instructions. I just wanted to be doubly sure that it doesn't matter, for this particular component. It's fine this way, right? I'm just concerned that there might be some subtle board layout consideration that makes it better to wind it the other way. Thanks, Adrian, KR0DAK

Hi Adam,
Thank you for your quick response. It turned out to be a cold soldering point on R16 GND side. 73 Pedro, LU7DID

Sorry for replying late. Check if you have swapped Q5 and Q6. 2N3906 and 3904 are very similar looking. Thanks, Adam

D4D Step 2 Failure
Dr. Pedro E. Colla (LU7DID)
Hi,
Building the D4D at Step 2 WITH the MOD on pag 25 implemented when testing the step upon powering the circuit the relay clicks but the amber LED goes and stays on. On previous STEP 1 testing the green LED went ON correctly. Any hint? 73 de Pedro, LU7DID

SST on Choc perfboard

Folks,
It is BG5JNT’s FB project. He built many projects based on my Choc perfboard and SST is his latest one. Nice design from NorCal in late 1990’s. Thanks, Adam

There are a few sandwich kits available from QRVTronics.com. There is also an option for a frequency display for a few bucks more. Larry Lovell 73's N7RGW http://QRVTronics.com Cell: 214-697-1729

Sandwich for 40m KN-Q7A
I have a 40m KN-Q7A that has been shelved for a while. I see there was an excellent looking kit called Sandwich VFO that greatly enhances the radio but shows as sold out. Is there a plan to re-introduce either the kit or the assembled module in the future?
Thanks! Bill K7WCB

Thanks for the feedback. GQRP is really an international club with a long history. I believe more Chinese QRPer will consider joining after my introduction.
Thanks, Adam
