The station operated initially as a receive-only IGate under Iain's callsign and was established as a digipeater on the 10th April 2015. It was shutdown on the 9th April 2016 as the NoV had expired. The station was restarted in December 2016. The equipment has since been used for packet experiments using AX.25 and TCP/IP.
The digipeater uses a single Tait T2035II fitted with the T2000-A60 dual port UART Interface Module. This module provides a computer control interface and an interface cable was constructed. More details about the interface cable will follow later. The software controlling the digipeater is Dire Wolf, running on Debian GNU/Linux. The antenna is fixed to the roof of the west wing of Fraser Noble building and is a vertical coax dipole (also known as a flowerpot).
The coverage map shows the predicted coverage of the digipeater. The coverage was not as great as had been predicted but was still very good. The main problem was due to the location of the Sir Duncan Rice Library which towered over the site.
In order to use the digipeater, you would simply send APRS packets as you normally would on 144.800Mhz with your path set to WIDE1-1 or WIDE2-1. MB7VX was the only digipeater in the Aberdeen area, and so higher values of "n" are essentially meaningless. If you do use a higher value of "n", your path will be rewritten when digipeated as if the path had been WIDE1-1. If you would like to ensure your packets are not digipeated outside of the city in the event that another digipeater does appear, you could also use the path CITY which other digipeaters should ignore unless explicitly told to use.
