Marc Here is a link to the Delphi code it is at the bottom of the page http://www.elexs.de/SI4735c.html Roy

Thanks again for the nice certificate, John! It took me a month to get to 15 countries, and the next 5 took another month. There is an awful lot of interference from Cuban stations here, plus a fair

Roy, A clarification: the code in the reference design I linked to is actually operating the chip in 3-wire mode. It nicely makes use of the MCU's SPI interface hardware, but the incoming

Hi Roy, I really appreciate the clear fashion in which you (and Scott) explain the SiLabs chip's operation! You are correct; I did not realize that the chip tunes for proper inductance after it

Hi Guys, Last night here in the North Atlantic produced a TA opening which was later than usual here ( about 1:30 AM Local 5:00 UTC ) Was hoping to ride the wave longer but the sandman took over .

Hi Neil, Thanks for your return. The merit goes to Jim and Gary because the too important photos that clarify once and for all any doubt about the identification of PL-380´s newest

Thanks I had not found till I saw your Photograph Looked an still could not see it -- opened other end that was still taped up and there it was So mine is a 2009 version 1 Thanks again Neil

Hi Marc Yes I came across that site. They had written their code in VB6 and were using the I2C interface to control the chip. They openly admitted it did not work properly and someone had rewritten

Hi Jim, Hi Gary ! Thanks both for the highly useful and enlightening photos and explantions about soft mute & SW stability ! Unfortunately my Pl-380 is old version. Because my english is basic

Roy schreef: Strange, but I think I saw some source code on the german site modul-bus ag (or so), where they sell a silabs chip on a usb-bridge. Marc

Hi Phil I would gladly do that for you but my G8 with the interface has the Si4734 removed at the moment. I will be able to do it toward the end of the week when the new chip arrives and I have

Hi Scott Thank you for the link to the sample C code and the explanation. All my code is written in VB.NET 2008. I have many years experience with it from my previous business dealings before I

Roy, thanks for your informative post! if you have time: tune your G8 to 5 MHz via the radio and then poll status via your USB interface, what is the capacitor value? how about at 10 MHz? 20

Hi Garry Looking at the video of the coil being moved indicates that the all that is happening is that you are moving the coil away from a peak that has already been established from a previous

Gary, Your results are interesting, but I think it would be good to take the experiment to the next level. A problem with your slider method is that it is well-known that loopstick Q is degraded

I think there is a bit of a misunderstanding here. The chip's datasheet indicates a range of inductance over which the chip's built-in varactor can successfully bring to resonance. This is
