ON 23d of May the Atleticoteam finished operation on 144 Mhz, dismantled 2 meter antennas and started EME on 70 cm with very simple setup: one 24 el. DK7ZB antenna and only 100 W! But it was again pile-up on 432.090 Mhz. I saw trace from -24 to -29 db, but decoded without problems. But after my first call the trace was gone! And no trace after several next calls. Seems, my mast-head LNA was dead! Burned or something else… In the HB9Q EME logger many HAMs give me report from -14 to -17 db. So, I stopped to call to 6W/PE1L and they informed me in the chat, that my trace was -19 db and they answered… So pity!
Sure, I have spare LNA (G4DDK). I decided to connect this LNA in the shack, close to transceiver. It was not hard, because I using separate TX and RX coaxial cables to aerial.
After connection and adjustment RX level, I saw 6W/PE1L again on my screen! -29 db and not every period, but enough for decoding.
I called and they are answered me immediately. So, day was saved and new DXCC on 70 cm appears in my collection. My report was -24 db. No screen-shot this time. I simply forgot ….
