- Chinese TCXO to improve short term stability of my Yaesu FT-857D. Also suitable for 897, 817 and probably other ones.
Quite cheap (payed about 12€ delivered).

They offered them on ebay or 15.-€ including shipping.....now they are 20.-€. I bought one for my TS-590SG a few Years ago.. A waste of Money. It was just a Piece of Junk. Tnx for your Video & happy Weekend. 73 de Uncle Günter 💯👌🙋♂
Great info. Thanks!
Thanks for your useful info! But frequency stability is only one aspect. Another would be a look on the noise. Is it getting better or worse after installing it?
Good point. I’ll have a look into it and perhaps post results in the next video where I want to try and measure the drift as a function of temperature.
Esses TCXO's não são maus! Mas também não são fantasticos. No entanto, para o preço não se pode pedir mais. Uma coisa que eu não gosto mesmo é o facto de estar virado ao contrario. Penso que nesse aspecto os chineses podiam ter feito melhor trabalho. Bom video. Uma abraço Victor.
Eu também não gostei nada disso. em princípio até tentei enfia-lo normalmente e só depois vi que não podia. Concordo, para o preço… obrigado por ver e comentar.
Um abraço,
Diego
Grazie un saluto dalla Scozia
Tnx for this info
How far off was the factory yaesu TCXO?
I don’t have the yaesu tcxo. I just swapped the stock crystal oscillator which was ok because I did aligned it. The problem is that is very temperature sensitive. There comes the chinese tcxo, much more stable.
@@IZ0MTW Oh I see, so the original crystal from Yaesu is not temperature compensated.
@@anonymous_friend correct
purchased one, as i've installed it mu 857 became absolutely unusable. sensivity wend down of 30 db and power output decrease at 80W. putted back the original and everything works fine. those chinese oscillators are pure garbage
