Re: TCXOM is ready for order
Hi Fred,
Hot air or heating plate are the best. If you don’t have either of them, a solder iron of high power (60-100W) will do the job. Just touch the metal surface and wait for solder melt and then move the crystal towards empty PCB side.

Re: TCXOM is ready for order
Wow, they went fast!? I bought some 25 MHz TXCOs to play with so I can wait-- but I really would like to make the ADX-S a clean mod, so let us know when you stock back up.? I easily can wait two weeks as I have be incredibly busy in my work and personal life for the last several weeks anyway and that won't change in two weeks.?
At some point you should plan on selling these on your website (the TXCO boards, I get not the modified si5351 boards).? There are a lot of ham projects out there that can benefit from that board!
Again nice job on the daughter card.?

Guys,
Shall I make the math simpler by adding 10 cents each? Let’s
make:
TCXOM - 5 USD each
Reworked 5351 module with TCXOM - 10 USD each
Shipping - 5 USD each order
The 1st lot will be gone soon. I will start shipping
tomorrow. The next lot will be shipped about two weeks later.
?
Thanks Bill. I can match your order.

Hi Adam
Just ordered 2 modules and 1 daughter board,
$24.70USD total but the new Paypal system didn't
offer a message to seller option, so I hope you will
be able to link the payment to this post?

Guys,
Why you will need this TCXO Module? No more
noticeable drift, even WSPR at full RF
output! The TCXO is supplied by KDS of
Japan. The spec says 0.5ppm.
I am offering two options. Please add 5 USD
for shipping each order. PayPal to rongxh@...
and leave your ship-to address. I have 30
pcs in stock at this moment.
- The green daughter board on the left,
only available to this group, 4.9 USD
each, 5 pcs max each order
- The reworked module on the right, will
be made available to public, 9.9 USD each,
5 pcs max each order

Thanks,
Adam

Re: TCXOM is ready for order
Yes, Barb. The error is just 2ppm, or 28Hz at 14MHz.

Re: TCXOM is ready for order
Tom,
It is my major intention to design the daughter board. The reworked module is just for your convenience if you don't feel comfortable to play with the small daughter board. After you replace the board, you will need to calibrate the frequency again. This is all you need to do.
Of course you can use it anywhere else. It is a generic modification to your existing 5351 module on hand, either original or clones.

I am late to the conversation but this got my attention. Can the reworked module and daughterboard be swapped into an existing ADX-S board for better stability and performance?

Doug,
It makes perfect sense. However, you guys put work on my
side, hi hi. The green daughter boards are readily available but
I will find time to rework the 5351 modules, so you will need to
wait for a few days.
?
I just ordered two of the complete modules.?
When I saw your first posting showing the mod I
ordered some TCXO's from Aliexpress planning to do the
modification myself. When they arrived I had to use a
magnifying glass to see them!?
It will be much easier just to replace the whole?Si5351A module than
working with the micro-sized TCXO or taking the risk
of damaging the existing Si5351A module when removing
the crystal.?
Many thanks for
offering this!?
