All N4PY software runs on windows operating systems Windows XP, Vista, and Windows 7, 8, 10, and 11 (including the 64 bit versions of XP, Vista, and Windows 7, 8, 10, and 11).
.A password protection scheme is used by the program. You can run the program for 10 days without a password. During this time, you should send the install number along with your call sign to firstname.lastname@example.org to get your password. Your password only needs to be entered once. It is good for all following versions until your subscription expires. When your subscription expires, you will still be able to use versions that came out prior to your subscription expiring. The same install number and password will allow multiple versions to run on the same computer but not on another computer.
My policy to give everyone all the passwords they need for all their own computers for their own use. The software license goes with the person and not with the computer. The N4PY software license is not transferable to another user.
Specific Download Information
To configure the program for your radio: a) Once you have downloaded and ran the install program, open the "Quick.txt" file. b) Find the section specific for your radio. c) Start the program and follow those specific instructions for your radio from the "Quick.txt" file.
Changes from version 4.51 to version 4.52 1) Fix displaying power and SWR on Yaesu radios.
2) Changed the low power range on the TX slider to 33. It was previously 25.
3) Fixed hang with Sunsdr radios using ExpertSDR3 when changing PBT.
4) Added saving K1EL echo back characters to a file. See the K1EL Keyer description in the N4PY help file.
Do not install the program in the "Program Files" folder. Windows 7, 8, 10, and 11 do strange things to programs in that folder. If you have difficulty downloading the program, I recommend you use Firefox as your browser. Firefox will download this program with no problem and it is a much better browser. I can assure you after being in business for 20 years that the file is completely safe and virus free. You may need to set n4py.com as a trusted site in Windows Defender.
For Windows 10, Smart Screen will say something like "Windows Protected Your PC". If you get this, click on "More Info". This will show the publisher as N4PY Software with my address in Louisburg, NC. Then click on "Run Anyway" and all will work fine.
