Packet Engine Pro

In 2003, the AGWPE author, George SV2AGW, released a more advanced program, Packet Engine Pro, based on his original, freeware AGWPE program.

The Pro version:

  • runs more efficiently
  • has an improved interface
  • has a setup 'Wizard' that simplifies both new sound card and TNC configurations
  • has several new features, such as Radio Port Sharing and alternative KAM-style tones for HF packet

In addition, the following features will work in PE Pro on Windows XP (and older versions). They will not work in AGWPE on a Windows XP (or more recents version). They work OK in AGWPE on older Win95/98/ME systems:

  • PTT can be controlled with the parallel port in addition to the serial port
  • YAM modem control
  • BayCom/BayPac modems, but only if your computer has legacy serial ports, i.e. not ACPI compliant serial ports ( ACPI is a power management/saving protocol)
  • TCP/IP Over Radio, a rarely used feature that lets a station without internet access link to a station with internet access and use the second station for very low speed internet access

Note: any client packet program that works with AGWPE will also work with PE Pro, and vice versa.

The Pro version costs US$49  after a free 30 day trial period. I encourage you to consider the Pro version because:

  • it is easier to use and more powerful
  • it has features that are not found in AGWPE and may never be added to AGWPE
  • your fee supports SV2AGW's programming efforts
