1. [Amps] ALS-600 QSK modification (score: 1)
Author: "Phil & Debbie Salas" <dpsalas@tx.rr.com>
Date: Sat, 28 Apr 2007 07:16:02 -0500
For those with an ALS-600, I came up with an inexpensive ($12) QSK modification that probably takes no more than a couple of hours to implement. Basically, I just replaced the open-frame relay with a

You might also consider the SPE 1K-FA amp available from Array Solutions. I got to play with one for a couple of weeks, and it is pretty nice. It includes an internal auto-tuner and a 4-port antenna

The switching power supply is a higher cost option. There is no diffference in amps between the one that uses the linear supply or the switching power supply. I have the switcher, and it works great

Good point. I just emailed W5BIG (the VNA designer) with this question. He said that the VNA2180 has been lab-tested with precision calibrated attenuators. The VNA2180 was off a maximum of 0.3 dB wit

The VNA uncertainty is less at lower attenuation levels. Supposedly better than 0.1dB at 50 dB attenuation. And obviously it is zero at 0 dB (straight thru coax) as that is where it is calibrated, Th
