Product information "New Packet Radio NPR-H 2.0"
New Packet Radio Modem Version 2.0
for long-range 70cm band HAMNET connections with up to 7W output Power.
I was amazed by the work of F4HDK. And as a ham radio guy who was active in packet radio in 1999 and the years beginning of 2000s I wanted to have something faster. HAMNET is nice, but you cannot have that long range transmissions as on 2m or 70cm bands. The NPR-H modem is compatible with F4HDK's firmware and can be used for ham radio guys as a standalone long range communication bridge, entrance to ham radio, bridge between networks, etc.
What is New Packet Radio?

- 70cm Frequency band - much easier to use / reaches longer distances than 2.4GHz or 5.6GHz (Hamnet).
- Transparent TCP bridge over 70cm
- 100% Open-Source Firmware
- Special modulation and codes to operate in Germany with 100 kbps
- Already many NPR master nodes in operation
- Up to 7 Watts output power @ 70cm
- SRAM 1024K
- Low noise amplifier and TRX
- Raw datarate: 110 kbps to 1 Mbps
