K3 KAT3 vs K2 KAT100

[VE3WDM]

Good evening to all,
I have both the K3 and K2 the K3 has the KAT3 tuner and the K2 has the KAT100 external and KAT2 internal tuners. My antenna is the Alpha Delta DX-EE antenna that  is mounted in my attic. Why is it the K2 antenna tuners (KAT100 and KAT2) can get me a 1:1 SWR on 40m but the K3's KAT3 only gets me down to 1:6? With the K3 I have re-tuned after the first tune so it can fine tune things but still it's 1:6 and I have erased the memory tune from the K3 to start fresh.  I have manually remove the coax from the K2 and reconnected it to the K3 and tried the tuner but am only able to get 1:6 SWR?? Any ideas!

There's a paragraph in the K3 Owner's manual, page 22, that may or may not
help:

Tapping ATU TUNE a second time within 5 seconds starts a more extensive
match search. The
ATU can even be manually tuned if desired. Refer to CONFIG:KAT3 for details.

Good morning Dick, thanks for the info and I am already pushing the tune button for the second time to fine tune things. I have also received an email suggesting I reload the firmware again seems this ham had the same trouble and the reload seem to fix it.
Thanks again for taking the time to get back to me.
