[Elecraft] Digital Modes DO Require Skills

I strongly agree, Andy. When folks say that it's the computer that makes the QSO, I observe that 1) I know no one who can read RTTY without some form of decoder, and 2) the computer did not put up my antennas, build my station, learn propagation, learn electronics, physics, transmission lines,

The OP was talking about 144 MHz.  For weak signal work I can't imagine not using a mast-mounted preamp. Even with sub 1 dB NF devices (that we paid dearly for when I was on EME) located in the shack, line loss is a killer. Wes  N7WS On 7/4/2019 10:01 PM, Jim Brown wrote: In today's world, a

In today's world, a mast-mounted preamp is a waste of effort for the vast majority of hams because circuit noise in the receiver is rarely the limitation on what we hear. Rather it's all the trash from the electronics in our homes and homes of our neighbors, in addition to power line noise.

Make sure you balance the station receive performance with that of the 1 KW amp.   Power is easy to generate.   Low noise receive performance is a challenge.   Start with a mast mounted low noise preamp, then low loss feedline such as 7/8" hard-line, and such. Remember, loss in the feedline

Don, Make certain the SignaLink is set for line level output, then in SSB mode, set the MIC select for LINE and adjust the audio input level. After that, turn MIC+LIN to ON and the mic gain knob will control only the mic level (the line level should stay as you set it). That should allow you
