EME needs Power.................

Fried the LNA - more than 800W on the antenna. I have used the SP2000 for more than 2 years without problems. The fault was not the relays but the layer on the PCB.

It´s time for a new LNA.

New Setup:

-2 x Tohtsu CZX 3500 coaxial relays - Switching >1KW on 144 MHz.

- LNA 144Mhz Kuhne MKU LNA144A with Noise figure 0,35 dB and Gain of 25dB.

RX line = Aircell 5

TX line = Ecoflex 10
