Hi All,

Deepu  (VU3TLD) shared his latest work.

Have fun

Hi Johan,

That looks to be exactly what I was hoping for. Makes the RadioBerry into a very neat transceiver.

Once the prototype has settled, I'd be very happy to run a group buy for the PCBs.

Regards,

Hi Johan, Deepu

Thank you for your work about a neat stacked transceiver.

Here is my concern about this stacking picture:
Is the gap between the top Radioberry board and just under Raspberry pi4 correct for the heat dissipation?
I've read somewhere AD9866's augmented heating as well as FPGA, no need to say Rpi4 CPU's high temperature.
Isn't there a need to have more space between the two boards?

Some time ago i did a repair for Cees PD0SBC he used some jumper extension and a nice alu case; which kept the RPI below 40 celcius.

Hi Johan,

Thank you for your information about a very nice heat sink armor.

I've found the same one on Amazon.co.jp:

I'll order this one. The price here is 2,200 YEN( 21 USD) including the shipping charges.
