It's been a while since I started a new AVR project, and I just want to be sure that I'm not about to get in trouble. Are there any known problems with using the combination of WinAVR, Ecros AVR ICE-Cube (purchased late 2004) and ATMega2560? Thanks, Phillip

I did the FFT on my pc, and passed the results to the AVR. (My 2GHz pentium runs at 90% doing the FFT. I doubt an embedded system could do it). On 5/6/07, kernels_nz wrote: > > HI David, > > How did you do the FFT ? Did you use a special chip or embedded > software ? > > --- In A

2007-05-04 by stevech11
That 450MHz antenna may work OK on 900 because 900MHz is the 2nd harmonic and the antenna will resonate. Certainly better to use a proper antenna. A small 4 element yagi isn't expensive for 900MHz.
2007-05-03 by Jim Wagner
The performance of an antenna depends on its relative size compared to the operating frequency. I would not expect a 900MHz Yagi to work very well at 450MHz. You can make a very simple antenna called a "J-pole" out of 300 ohm twin lead and some coax (to connect to the radio). You

Thanks, all, for the advice. I probably will try the Maxstream devices, although the freq. might be a bit high for my steep terrain. The FRS devices are around 450Mz, and just barely work, at about 100mw. I haven't tried a directional antenna with the FRS, but I have a yagi that
