As part of RRI investment in Puerto Rico, the first digipeater has been tested and is ready to ship. The digipeater systems being provided will operate from float cells maintained at full charge. The systems will also detect loss of AC mains power at the communications site. When power is lost, the digipeater transmits a DTMF sequence every 15 minutes until power is restored. A separate receiver and decoder package is also provided, which can receive the alerts for multiple remote locations, thereby ensuring that the RRI and ARES teams are aware of the status of each system.

By building out a robust packet radio network and combining it with the RRI Digital Traffic Network and Winlink gateways, the radio amateurs of Puerto Rico should be well equipped to respond to future disasters in a cohesive and professional manner.

The design and construction services were donated by Signal and Communications Associates on behalf of RRI: https://signalcommunicationsassociates.com/

"This is a photograph of a homebrew AM transmitter someone made in 1964 that I recently restored alongside with a National NC-303 I restored. I acquired the transmitter about a year ago and I have no idea who made it or any history of it. I wonder if you can post it to get some visibility hoping that someone may recognize it and provide information on it." - Sean Davis N8VIL

Maybe someone has some information on this beauty. Thanks Sean.

A fine morning picking up radiograms from W5CU in Oklahoma via the HBN CW Net. In an era of digital communications, computers and printers, there's still something very satisfying about copying CW traffic on a mill, particularly on a snappy circuit with a good operator on the transmit side. Better yet, even if there is an extended power outage, the old Re*****on Radio-Telegraph Typewriter (mill) will still work.
