The issue I spoke about on the V4 with 20m and CW FCC tests

Laurence Oberman

I had mentioned this issue I have on the V4 that looks like RF
coupling or leakage when testing CW on 20m for FCC compliance.

I don't see it with SSB but if you transmit for long enough spurs will show up .
See the document I shared.

I only just got my Axicoms to replace the relays.

Strangely enough not seen on 15m, 17m or the higher frequency bands,
also not seen lower than 14Mhz.

Other than that the V4 has been fine, now replacing with V5 and my son
gets the V4.

Question is who else has see this.
