![]() The location is my back yard. On the subsequent days I moved the antennas down to the ground and extended the legs on the tripod. On day 2 I got a good preamp and added a 100 watt amplifier. I was able to copy KP4AO's SSB about 80% and got 100% copy on CW. I called long and hard but they did not hear me. |

Also, here are links to spectrum recordings made
at Arecibo: You need to use Spectravue to see these spectrum displays and to tune in and listen to the signals presented therein. You can download for free here: Spectravue Download. Be warned that these files are very large (about 1 GB each except EME_8 which is much smaller). Below is a screen shot of one of KP4AO's first receive sequences in the EME-7 file. Note the narrow gray line in the black area. Below it you can see my signal from Saturday when I was running 100 watts. If you download and listen to this file you can clearly hear me calling them - proving that a small antenna and 100 watts was enough to easily work them (except for the competition!). Note that to use these files with Spectravue you need to click the tab named "Wave IN Setup", enter or browse to the desired file, then enter the center frequency as 432040000, and check the box labeled "Invert Spectrum". Close the box and click the start button. Select the CW-U mode. Now you can click on the various signals to hear them, or tune by entering changes to the Demod frequency box. You can also tune by using the up and down arrows to increment or decrement the individual digit in the demod box that is selected by the mouse. You may also want to try various Span settings to spread the signals more or less. |
