A friend forwarded a recent post regarding preamps. I noticed that the data on the one study was from 2010. It also didn’t mention two very fine preamps -those made by SSB Electronics and the extraordinary 2meter preamp made by WA2ODO that many EME operators use. They post the lowest noise levels and highest gains I’ve ever seen, but they do not have relays so they cannot pass rf and relays are therefore required. They are also inexpensive.
