I have used both my K3 and K3S with two Speed-X bugs - Les Logan and EF Johnson - since Oct 2019. Over 700 contacts in the log for the Straight Key Century Club. Some of those contacts were with different tube/boatanchor xmtr or QRP rigs, but the majority with the bug. I've not used a paddle since Oct 2019. I have had no issue with those two bugs, nor any other bug that was in short service in that time. No de-scratcher used, no capacitor across terminals. Stock, as-is. So it might make sense for any bug user to check setup of pendulum/contacts etc, apply some DeOxit or run thru some fine paper between the contacts. But I don't see any presence or absence of any circuit in the K3 required generally. I do use a straight key sometimes, but the above numbers are the telling sample. On my BA rigs, I do employ a simple keyer in-line with the bug in Straight Key mode, but only to provide a side-tone for xmtrs without side-tone generation.
