[Elecraft] K2 S-meter output for antenna measurements?

Mon Dec 2 23:03:00 2002

As Ron mentioned, Spectrogram may do just what you want with no extra
hardware.

For applications where you need an A/D, DataQ has a very inexpensive
unit that plugs into the PC serial port. It has 4 chan, 10 bits, 240
samples/sec, $25.
