Lower spreading factors mean faster chirps and therefore a higher data transmission rate. While APRS and Winlink use AX. Traditional Modes? • SSB and CW are “general purpose modes” The overwhelming majority of APRS activity has been sent over VHF FM radio networks using 1200-baud AFSK packet radio modems a. Robust Packet occupies the sweet spot in between these two techniques offering functional data speed in a small 500 Hz wide footprint. 11. See Q170. since its start. We have a Vara FM RMS located on Glenada. Some Software TSTHost > tsthost. Audio level consistency. The protocol for all VAPN HF ports is the 500 Hz wide Robust Packet mode. In this mode there are two states, carrier on and carrier off, hence the name off/on keying. 66. Due to this high reliability, P4dragon modems allow transmission of safety relevant data via shortwave, and provide an excellent value for money when compared to many A cousin of packet, pactor, and Robust Packet. PACTOR/ PACTOR II & III • PACTOR, PACTOR II, and PACTOR III are hybrids of Packet w/the HF functionality of AMTOR. Spoiler alert: The SCS modems did very well as you would expect with PACTOR 4 dominating all other HF modes over the range of tests performed. Today, when most hams hear ‘packet radio’ they usually think of APRS or Winlink. If you are using WINMOR, consider changing to ARDOP or VARA. io Subject: [pactor] New Firmware for PTC-II series modems Hi all, Pactor-III mode was developed after the PTC-II and PTC-IIe were introduced, and was an “option”– part of the newer firmware-updates but had to be “unlocked” with a purchased license-code. As of July 2021, the fog organization has over 250 worldwide stations using and enjoying this software. 33-37 Packet, QST April 1992, pp. Open source means experimentation and innovation in Amateur Radio, like custom firmware for Xiegu X6100 that implements FT8 on the device itself!
