Tried looking through thread but no luck finding the desired info. Already have the Clapp oscillator from previous buy, and before getting into the new buy, was wondering if anyone could offer an opinion on the objective upgrade in performance from building an SC based oscillator. TIA.

This thread is a bit of a mess, may I suggest that you split in two one for the gb, the second for the technical part?

@Andrea

Can I use 33uF capacitors instead of 22uF in the C17 and C18 positions in the schematic of TWTMC_D&D ? Those ones are located just below the LD1085 regulators.

I have found problems sourcing the 22uF, just wondering if 33uF will work as expected (they have even lower ESR)

Cheers
Pepe

Yes, 22uF to 47uF should be fine. Since it improves ripple rejection, higher value is better.

Thank you Andrea !

If there will be a new batch then this thread will be splitted in two parts.
For the moment I prefer to keep one thread only to avoid confusion until the current Group buy will be closed.

 

[Nikon1975]

I am really interested in the technical findings of this work, that are almost impossible to find here at this stage.

Closing the Group Buy

Since I would finalize the order to Laptech, the Group Buy will be closed within February 15.

If you are in the list but you have not yet sent me the order form, please send me it as soon as possible.

Next week I will send a Paypal request to all the members who have sent me the order form.

 

[RollE2k]

Andrea, i have sent the order form - but i realize i will not have time for this (we just got our second kid... and i have alot of projects already that i have no time for). Can you remove me from the list?

Ok, just removed.

Andrea,

Is the coming GB just for the crystals? I may want crystals on different freqs as my previous sent order form. Should I just send you the order form of crystals and update the interest list with the boards?

This GB is for the crystals and the boards previously released (Clapp oscillator and daughter board). The Driscoll oscillator and the oven boards have to be tested with SC-cut crystals (to do after I'll receive these crystals), so they will be available in a second moment, after this GB will be closed.

I got your order form, you could add the boards developed for AT-cut crystals only (not the TWTMC-D and the TWTMC-OVN).

Thanks Andrea. Updated ordering form sent.
