Spent a fair bit of time today looking into the following issues on 160M on G5RV & tuning :

Problems intermittently on FT857 - Tuned well, Tx & receive good, the auto tuner kicks in & upsets SWR. Sometimes helped by joining the 2 halves of the T, sometimes not.

Problems most of time on 817 resulting in V low signal

Test setup & results:

used the 817 as the issues are worst there. 

Connected UHF cheapo SWR meter & manual tuner

Signal results

Manual explains power output very poorly for 817.
