I was wondering if LNA mounted 50 cm from the IC-9700 + 15m Ecoflex 10 makes sense... Tests using setup like this (see picture) shown it makes sense... well how was I testing it? I've installed a 23 cm beacon about 70 km from my home qth. Beacon has power lower than 100mW... and with LNA I see it on the IC-9700 waterfall and can hear... while without it...rarely. So I decided to make a more LAB test;) This is my setup: Signal generator HP 8642B frequency 1296200 kHz, amplitude - 140dBm. About 2 meters of RG-223 cable. LNA (vhfdesign 23cm EME 1st SAW - 18dB gain 0.3 NF) with relays that you can see on picture above (with some semi-rigid). About 1 meter of RG-223 cable. IC-9700 run on 1296200 kHz in CW with 500Hz filter and AGC-OFF. USB cable and computer with Linux and baudline (audio spectrum analyzer). Results... (distance from top of background to maximum peak) LNA only - 22.14 dB, background ~ -56 dB PREAMP only - 18.56 dB, background ~ -65 dB no LNA no PREAMP - 13.86 dB, bac
