Dnes odpoledne jsem se konečně dostal k dokončování SDR Softrock RXTX v 6.2. Namotal jsem všechny cívky a transformátory. Celé to zabralo přes 2 hodiny. Výborný popis jak motat transformátory má DF7TV (sice pro verzi 40/30m, ale to vůbec nevadí, liší se to jen počty závitů)

Hello Ondra,
Sorry that I do not speak your language.
I hope your SoftRock transceiver is working and you have a lot of fun using it.
Here I started experimenting with the SI570 programmable XO which is intended to replace the crystals used in my 40m/30m transceiver so far.
All the best; I hope we meet someday on the bands. Perhaps a two-way SoftRock QSO could be done.

Hello,
Thanks to the Si570 board kit (Dave, WB6DHW)and to the SI570 group buy
(Tom, KM5H) I was able to start some experiments with the SI570 using
a PICAXE 28X1 for the control and an external I2C EEPROM to store
register values for frequencies.
So far I built a simple circuit (SRC11) on a breadboard and started
programming the PICAXE processor. That is to say I started to learn
how to program the processor :)
Thanks to Cecil, K5NWA the current status is shown in a blog at
http://softrockradio.org/picaxe/src11 .
Your comments to the blog are welcome.

Zdravím Vás,
kde prosím levně sehnat Si570
10 - 1400 Mhz ?
Stavím SDR rádio.
Děkuji za rady.
