• Introduction to PACTOR (Level 1).
• Why 9600 bps packet doesn't work very well on your typical HT.
• N6GN's Higher Speed Packet WWW Page
• If you are serious about packet, you should see KA9Q home page (at Qualcomm), especially his Amateur Radio Digital Communications page.
• VE2DM's packet page?
• APRS message archive at TAPR. [There may be a more actively maintained archive elsewhere. Do you know where? KD6PAG ]
• Optimal FSK shift.
• How to detect PSK.
• Short discussion of Troposcatter Packet.

• New node software called FlexNet available from [email protected] (Eric Bertrem) from Gunter Jost, DK7WJ. "FlexNet is FREE, it has no commercial purpose and can only be used on a ham-radio basis."

• WB6AOX has a PC/C64 packet modem in home page, including schematic and Stephen Holmstead's article, Basic Satellites.

• Have the Russians got there first? VFast28.8 GMSK Radio Modem is a commercial kit that claims to support moderate speed packet and interoperate with a existing G3RUH 9600 bps modems. It uses "GMSK data modulation method" and developed "specifically for Radio Amateur use... The board illustrated here is simple to construct and measures only 140mm x 60mm. It uses simple to buy componants with 4 IC's required. The VFast28.8 modem kit comprises a high quality pcb with full ground plane and careful analogue / digital separation, a preprogrammed microcontroller and a Technical Manual. The GMSK modem IC used can be obtained direct from the manufacturer. Full contact information is given in the VFast28.8 manual."

• The MacAPRS author, WU2Z has a home page now.

• Where to find the BPQ packet software and one person who's willing to help.
