While checking with a local ham CW on the 10 meters band, we found that the tone at his receiver was no pure it sounded rough, only on this band, the other HF band were OK. After discarding SWR, ground, paddle cable and other connected cables I found that the problem is with the RS-232 cable (connected at the radio port and connected or not to the computer). I installed a couple of split ferrite beads and the problem was cured. Unfortunately I do not have another cable of different length, the actual length is 72 inches.
