Thank you=2C John=2C for the advice=2E Deleting the ctr- and usr-files did = the trick=2E Tracking during lock off seems to work when using direct keypad entry from the NRD535=2C but not from the spinning wheel=2E This is also the case with the frequency display in the receiver- window=2E Perhaps the computer is busy with some calculations as returning back to lock on also seems to be impossible=2E The only way to overcome this situation is to close the program=2C which happens without warning messages=2E Deleting the usr- and ctr- files didn't solve the =22more than 1 MHz=22- problem I mentioned before=2E Cheers for now ! Jouni =3E =3E JOUNI and others =3E =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =3E I forgot to mention that with the new features=2C you need to delete your =3E existing CTR and USR files for the receivers=2E They will then be recreated =3E and the new features will be there=2E You can do this either of two ways=2E =3E =3E (1) Manual=2E With E4 off=2C open the =3Cprogram folder=3E=5CUSER fold= er=2E Erase any =3E file *=2ECTR and *=2EUSR=2E The prefix of these files will be there receiver =3E name=2E =3E =3E (2) Automatic=2E Without any receivers running=2C go to the Beta page = in the E4 =3E properties=2E Press the Reset button=2E =3E =3E E4 always recreates these files the next time you run the program=2E (The CTR =3E file needs to be recreated when new features are added=2C as is the case =3E here=2E) Sorry about that=2C I should have been explicit=2E =3E =3E GUY ATKINS =3E =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =3E Yes=2C each receiver must have a unique name=2E (This means you can also run =3E two versions of the SAME receiver=2C as long as you give them a unique name=2E) =3E And=2C yes=2C to run two receivers at once you must have two serial ports=2E Some =3E laptop users get around this by using a USB-Serial convertor which breaks =3E out to multiple Serial ports using only one USB connection=2E (I know the =3E multiple port situation is rare for laptop users=2E Many of the newer IBM =3E machines do not even have one serial port!) =3E =3E Absolutely=2C both receivers can be active at once=2E You can have each one =3E linked to a different database if you want to=2E However=2C you can only =3E control one receiver at a time from a particular database=2C although you can =3E switch between either=2E Also=2C only one receiver will accept keystrokes for =3E frequency entry=2C etc=2E=2C at one time=2E You select which receiver = is =22active=22 =3E by clicking on the red LED in to top left corner of the big window=2C or the =3E vertical receiver name in on the left side of the small toolbar receiver =3E window=2E =3E =3E SHORTCUTS =3E =3D=3D=3D=3D=3D=3D=3D=3D=3D =3E I have figured out how to make the shortcut keys for entirely user =3E definable=2C and will be adding this to the properties box shortly=2E = That way=2C =3E you can customize your shortcuts / hotkeys=2C exactly the way you want them=2E =3E (There will be some limitations=2E Certain keys will be reserved for direct =3E frequency entry=2C F1 for help=2C and certain other keys for navigating= within =3E the database=2E Otherwise=2C they will all be under your control=2E =3E =3E Current Activities =3E =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =3E Focusing right now on receiver control=2C finalizing the current drivers=2C and =3E will add Profiling and Reporting=2E The next receiver I add will likely be =3E the RX350=2E =3E =3E 73 John =3E =3E =3E =2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E= =2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E=2E Oma s=E4hk=F6posti aina k=E4yt=F6ss=E4! http://luukku=2Ecom
