2020年7月31日 · The next step in our EME project is to assemble the four M2 Antenna Systems 2MXP28 Yagis. These antennas are large, cross-polarized yagis. They feature 28 elements each on 34 1/2 foot booms. The design operates as an independent horizontal and vertical Yagi on a shared boom and each plane have an independent feed point.

I have resumed monthly EME activities now that my system is working again, still using a single 9el M2 yagi, 140W output and moonrise (no elevation ability) only. As of June 2017, I have completed contacts with 105 different stations using this system.

•eme is challenging. •on 23 cm all you need is a yagi, ~50 w, a computer and jt65! •it is pretty easy with a big station, but there is still a lot to it: accurate freq, stability, time, moon tracking, doppler, etc. •with a weak station, all the above plus must understanding how …

Two-way radio communication on VHF and above using the Moon as a passive signal reflector. Commonly referred to as “moonbounce”. EME shack? Definitely *NOT* “plug and play”! But - Why so difficult & expensive? *BUT* be realistic!! You will …

The best time to operate 2m EME is when perigee, high northerly declination (for northern latitude stations), minimal sky noise, lowest degradation and evening hours all coincide. However, this optimal situation happens only every nine years when the moon is as close to the

life on 70cm EME! Simple yagis and modest power can be used to make EME contacts on this world wide band. A LNA is needed for most QSOs.

2020年7月31日 · The four EME Antennas in our array will have a total of 112 elements! These antennas are large, cross-polarized yagis. They feature 28 elements each on 34 1/2 foot booms…

For EME a clever switching system from IK2UWL is shown at the left picture. This system was used at the EME-expedition CE0Y/DK2ZF in October 2010. For transmitting always circular polarization is used. The two Yagis (are Yagi.groups) are …

2021年6月9日 · With most EME stations using four or more Yagis and high power, most of the heavy-lifting on my two-way work is being done by the other station. With the extra sea-gain here, my single 9el Yagi performs more like an array of four similar Yagis.

2021年1月2日 · Goals for Our 2m EME Station 2 • Build an 80th percentile 2m EME station for Contesting & DX’ing ü Project began late in 2019 with a new tower ü Four Yagi X-Polarized Antenna System ü Dual Receiver Phase I Station with Manual Polarity Selection v Improve station performance based upon operating experience • Implement Adaptive Receive ...
