[Elecraft] internal vs. external ATU

[Randy Farmer]

Say what? Both of mine do. After a power cycle, all the tuning relays 
do come up in the open state, but a few dozen milliseconds of low 
power RF at the desired operating frequency will restore the proper 
matching condition almost instantly. As a matter of fact, one of the 
annoying little quirks of the 230 is how very difficult it is to make 
it "unremember" the setting for a particular frequency. Do you have 
the "Tune From Memory" jumper in your tuner set to "NO" by any chance?
