T.R.A.S.H. Technical Info;

It takes a LOT of time and equipment to build a linked radio system (Commercial, Amateur or GMRS)

EACH T.R.A.S.H. RF site consists of;

1: a Receiver and a 100% duty-cycle Transmitter
(The Motorola SLR5700 commercial repeater we use at many sites, has both RX/TX units in a single 1U chassis)
We also use Motorola GR1225/RKR1225 repeaters
2: Duplexer (combines the receive and transmitter into a single antenna)
3: Receive BpBr filter
4: AC/DC Power supply (some sites also have DC battery/generator backup)
5: Repeater controller (the physical device between the receiver, transmitter and internet)
We use a raspberry-pi 4B-2G and a RA-25, or a RTCM for most sites
6: Internet connectivity (some of our sites utilize a 5ghz RF microwave link to get internet to the site)
7: Commercial grade antenna, feedline, Polyphaser impulse protector, grounding, etc
8: Back-end server for each node at our data center
9: Access to a site, leases and insurance

Also required: A 4x4 vehicle to access the sites in all weather conditions,
Time and funds to maintain the system, buy new equipment, bribes, beer, ammo, burritos, etc

It's a huge investment and a life-long passion that I freely offer to the amateur radio community - Neil Addis W7FED
