Communication between the computer and the PSKMETER seems to be erratic. Whats the problem?
RF! One way to confirm this is to feed your rig’s output into a dummy load instead of an antenna. If you observe that all these problems with the PSKMETER disappear, you have a problem with either RF leaking into your computer, or reflected RF from your antenna coming down the coax ground braid. There are several things you can do to clean up your RF environment: 1. Add 3 or 4 loops in the coax at the antenna end of your feedline. 2. Put toroids onto all the cables attached to your computer, including the audio cables, serial cables, even the keyboard, mouse and power cables. This is just good practice for any PSK31 station. 3. Check your grounding. For example, make sure that your computer’s ground is the same as your transceiver’s ground (i.e., connect the coax ground to the computer ground). 4. If all else fails, try using a grounded metal enclosure for your meter (or wrapping copper tape around the plastic enclosure, being sure you spot solder the seams and ground the copper). Befo
