Radio Hardware

Firefly uses several variants of commercially-produced, commonly-available amateur handheld transceivers (HTs).

BF-888s

Bf-888s.jpg
Name BF-888s
Channels 16
Bands UHF only
Frequency Range 400 - 470MHz
RF Power ~3W
Operating Voltage 3.7V
Users Dirt Rangers, other Safety Cores, anyone who doesn't need a different radio

Links

UV-5R

UV-5R diagram
Name UV-5R (also UV-5Rv2, UV-5R+, etc.)
Channels 128
Bands UHF/VHF
Frequency Range 136-174MHz, 400-520MHz TX
RF Power ~4W
Operating Voltage 7.4V
Users Khaki, anyone on a long shift

The UV-5R has several ~identical-looking variants. When programming the radio, it's important to look at the model plate on the front and see what you have. If it's not "UV-5R", you likely have one of the custom variants -- see Baofengtech's compare chart for more info on the differences. They all have basically the same capability, with the exception of the RD-5R, which is a digital radio.

TYT MD-390

MD-390
Name TYT MD-390
Channels lots
Bands UHF
Frequency Range 400-480MHz
RF Power ~4W
Operating Voltage 7.4V
Users For 2018: GGGP, GTFO, Accessibility

This is a DMR (Digital Mobile Radio). It can be used on the analog UHF channels in a similar fashion to the other radios, but its primary use is on the digital channels. For users, its operation is the same as the others: push to talk.

We may expand our use of DMR in the future depending on how 2018 goes.
