Get On The Air — AC Log POTA layout recipe (not an .efl)
https://getontheair.app/guide/logging/n3fjp/

N3FJP AC Log 7.0.4+ includes POTAConfig.efl. Load that.
Path: Settings > Edit Fields Displayed, Position and Tab Order
      > Load a Saved Configuration

Default folder:
  C:\Users\<you>\Documents\Affirmatech\N3FJP Software\ACLog
File > Show File Locations if needed.

If the wizard asks to apply POTA Other-field defaults:
  YES  if you have never named Other fields
  NO   if you already set MY_SIG / MY_SIG_INFO yourself

We do not ship N3FJP's .efl (it is their file). If you are building
a layout by hand, show at least:

VISIBLE ON MAIN FORM
  Call
  Time On
  Band
  Mode
  Freq (if CAT)
  RST Sent
  RST Rcvd
  Grid Square          <- hunter, ADIF GRIDSQUARE
  State
  Other: MY_SIG
  Other: MY_SIG_INFO
  Other: SIG           <- P2P
  Other: SIG_INFO      <- P2P
  Log Contact button

TAB ORDER (pileup)
  Call > Time On > RST Sent > RST Rcvd > SIG_INFO > Log

THEN UNCHECK "Enable Repositioning All Fields on Main Form"

Save as your own name, e.g. POTA-Field.efl, in a folder you back up.
Some operators keep a second POTA-Management.efl with more QSL columns.
