To followup the topic of antenna matching/SWR from the meeting last night, I
looked up the recommendations from ICOM and YAESU for two of my HF rigs that
do NOT have an internal tuner.

For the IC-7100, ICOM recommends an SWR less than 1.5:1 and says that power
foldback will occur with an SWR greater than 2:1.

For the FT-891, Yaesu recommends an SWR of less than 1.5:1 and does not
mention power foldback.

So Chris AD2CS was correct to question the statement that any SWR less than
2:1 is no problem.
