Hi All,?
Thanks for the replies. I¡¯ll go for the 1N5711W SMD for both D1 and D2 and hope for the best!
It gets worse though- the strip of 1uF SMD capacitors are actually measuring at 8.5uF.?
I contacted the seller and they said these are fine to use. They also offered to post the missing Schottky diodes- so full credit to them.?
Looks like most of these capacitors are used as stray RF filters between + rails and GND.?
Increasing the values of these would just increase the upper limit of the frequencies they filter out right?
Has everyone just stuck with the 1uF capacitors or would it be worthwhile using the 8.5uF ones instead?
Many thanks folks, 73s

??? ??? ??? Grant,
You may use both but as A: ¡®use either a BAT41 or 1N5711 for both
D1 and D2¡¯
Not two different ones .

Hi Everyone,?
I got a very cheap N7DDC kit from eBay a few weeks
ago, but it unfortunately didn't come with all the components.
No complaints from me- i wanted it to be cheap!
The missing bits are specifically the two Schottky
diodes D1 and D2.?
On the github schematic they are listed as ¡°D1, D2 -
BAT41, 1N5711¡±
Does this mean:?
A: ¡®use either a BAT41 or 1N5711 for both D1 and
D2¡¯?
or?
B: ¡®use a BAT41 for D1, and a 1N5711 for D2¡¯
Both look to be very similar but different
components, but i¡¯m not an expert.?
As these are both THT parts, I was also wondering if
i could use SMD parts instead?
I guess i could form the leads to match the pads,
but i¡¯d rather not if possible.?
I think a 1N5711W (a SOD123 package, pretty much an
exact replacement for the 1N5711) would fit the pads, but can
anybody confirm?
Datasheets are here for them all for handiness:?
Many thanks,?
