## Overview
|
|
|
|
The UV-5R family of radios are cheap 4W micro handheld transceivers with
|
|
reasonably good stock features especially given the price. They can be
|
|
modified to bypass the on board MCU, which is a write once chip that
|
|
cannot be modified. The UV-5Rs are software controlled radios (not SDRs)
|
|
they have hardware filters that prevent the same kinds of band expansion
|
|
as the UV-3Rs.

## Notes
|
|
|
|
### Performance
|
|
|
|
#### MCM2013
|
|
|
|
- Receive sensitivity is pretty severely lacking. UV5R had issues at
|
|
WaterPoint 4 on nets C/H/G. No received signal at all. All other HTs
|
|
at the same location had perfectly fine Rx.
|
|
|
|
### Recommended Accessories
|
|
|
|
- A wide based flush fit BNC (or similarly durable connector) adapter
|
|
(sometimes called an antenna saver) given the short mating cycle "SMA
|
|
connectors are rated for up to 500 mating cycles" [citation via
|
|
Wikipedia](https://en.wikipedia.org/wiki/SMA_connector)
|
|
- example: [SMA Male to BNC Female
|
|
Connector](http://thumbs4.ebaystatic.com/m/mUgb7YRjFqInb9GoQZVkQMw/140.jpg)
|
|
- Also you can replace the adapter much more easily than the SMA
|
|
connection in the radio.
|
|
- You can even apply some threadlock (the light duty stuff) to the
|
|
threaded part and still keep the groundplane continuity because of
|
|
the wide base on the adapter touching the rim of the SMA socket.
|
|
- Get a dedicated antenna for VHF and UHF (or whichever you will use the
|
|
most). The dedicated antennas will do wonders for performance as the
|
|
stock antenna is really pretty horrible and multiband antennas in
|
|
general can only be so good on any given band they are tuned for
|
|
before the others suffer, so they end up being okay at best on all of
|
|
them. If you followed the above then get a BNC terminated antenna and
|
|
don't worry about adapters for the antennas.
|
|
|
|
## Hardware Versions
|
|
|
|
There are a large number of internally identical radios with very
|
|
nonstandardized names in the UV-3R and UV-5R family.
