 Most Prices and Discount levels have been reduced recently.  

I'm afraid I will have to disable the Store for a while while I take inventory of my stock.

 

After attending a nearby Hamfest I find that over $2000 worth of parts were stolen, and many parts of which I had 1000 in stock are completely gone. The theft was very selective, some parts in drawers with many others were taken but the rest left alone.

 

Sorry for the inconvenience but this could not have come at a worst time, right now due to the economy I'm barely making it money wise, so replacement of the missing parts is going to take a long time.

SI570 programming and display

Submitted by pa0akv on Sun, 05/18/2008 - 07:32.

Today I finished the prototype microprocessor board. I added the smd components on the copper side and I hope to start programming next week.

The LCD display and the band/bandsegment switches are mount and I soldered the wires to the connectors.

Now I can mount the brainboard and start programming. As a result the band/segment information will appear on the LCD display.

I wrote a small program already for my EasyPic3 system and will convert the code to this project.

So coming soon the first resulys..........

To show you some results watch the photo's

SI570 programming

Hi André,

Sure looks nice what you are doing there.
I'm still using RXTXv6.2 using only one xtal, but the postman should deliver both the SI570 and an AMQRP-dds kit soon.
Hope I will be able to "hook up" shortly.

Good luck in your programming efforts!

Hello Christiaan, nice to see other people building these things. DDS 60 works very nice with the RX and RXTX kits. If you like you can use the software I wrote for the 16F877a. I don't go further with this concept because I like a seperate SI570 osc subsystem.

Hope to see your results soon so we can share sollutions.
