How does the RF signal “T” to PSKMETER?
The PSKMETER is a high input impedance device, and not a 50 ohm load. Therefore, you should never terminate the output of your transmitter directly into PSKMETER. This would not be good for PSKMETER, and the reflected power would not be good for your transmitter’s final amplifier. Instead, run a short length of 50 ohm coax cable from your transmitter to one side of a BNC “T”. Plug the T into the PSKMETER, and then plug the other side of the T into the feedline that runs to your antenna. This way the PSKMETER merely sits on the feedline and can sample the RF voltage as the signal goes out to the antenna. IMPORTANT: Do NOT run a “stub” cable from your transmitter to the PSKMETER. That will result in a very dramatic degradation of your system’s SWR!
