E montei um desses em meu radio cobra 148 gtl. Funciona bem. Mas por questão do codigo fechado e limitado por conta do arduino. Estou desenvolvendo um software próprio. Que vou deixar aberto, depois de completo.Alguém tem alguma informação nova ou experiência com a instalação de um desses?
Hasn't been an obvious problem in the ones we have installed so far. I was skeptical about the Si5351 chip, but so far so good.
What I really want to figure out how to do is use all three outputs from that chip to replace all 3 oscillators in the Tram D201A, not just the channel LO.

Etherkit SI5351 library
has everything you need to turn on any of the clocks with whatever frequency and power level you need.
Chris have you done a D201a yet with these kits ? I got two kits from Troys for the Black Ch sw 201a & 23 ch 201 etc here, started on it , then life got in the way, and need to get back to it. I got opto relays etc to detect the radio mode sw change. If you had any notes on what you did there, I would appreciate a copy please?

Nice of the author to make the source code available under GPL 3 license.Just found out about this one
