you can save that as the basic setup in Chirp. Then you enter your memory frequencies, offsets,
tones etc., save that file under an appropriate filename, and then upload to the radio.
You now have all of your setup info and basic radio preferences saved along with the memory
channel assignments. This is the clue to saving hours of frustration with the program not
working and in not losing your basic options!
After that all you need for most uses is Chirp (which has many profound advantages in memory
programming) unless you need to redo some initial settings again.
Remember that both the programs require some initial data from the radio in
order to set themselves up, and any changes need to be shared on both programs.
How do I program when using a MAC?
From message 4152, with slight edits for editorial and long-term reference purposes:
1) The cable. I got a USB to TTL convertor ready built from eBay - search for 'PL2303HX USB
to TTL Converter Module' as an example. Mine cost £1.92 delivered [January 2012] from Hong
Kong and arrived in a week. This comes with a four-wire lead with push-on connectors, so I
also had to get a cable with a four-pin 3.5mm jack plug to connect to the UV-3R. This came
from Amazon - search for something like '3.5MM Stereo Jack Plug To 3.5MM Stereo Jack Plug'
and cost £1 delivered. So cost of the cable was £2.92. You need to then cut the jack plug cable
in two and connect it to the leads from the TTL module - module GND to plug BASE, module
TXD to plug FIRST RING, module RXD to plug TIP. The plug second ring is not connected to
anything, and you should not connect to the module VDD at all. Plug the cable into your Mac
and you should see a red LED, and plug it also to your UV-3R SP/MIC socket and you should
see a green LED for RXD.
2) The driver for the cable. You need to download the driver for the PL2303 convertor chip
from Prolific at http://www.prolific.com.tw/eng/downloads.asp?id=31. Scroll down the page
to 'md_PL2303_MacOSX10.6_dmg_v1.
4.0.zip' and download it. Unzip and install the .dmg as usual - there's a good PDF install guide
in the package if needed. You might need to restart your Mac now. Without this driver the
convertor module port is not seen by CHIRP.
3) Get the latest version of CHIRP - the programming software for the UV-3R and other
rigs - from http://chirp.danplanet.com/projects/chirp/wiki/Download. Scroll down to 'chirp-
0.1.12.app.zip'. You also have to download the Python runtime from the same page - 'KK7DS
Python runtime'. Install the runtime first, then unzip the CHIRP package. It is all quite intuitive.
4) Open CHIRP by the usual double-click on the Chirp-daily.app that you unzipped; it may take
a while to open X11 and get going, and will probably need to download files from the internet to
initialise. On my Mac it fired up fine in a minute or so. You get a blank app page initially, which
can be a little disconcerting.
5) Connect your UV-3R to your cable, and on the CHIRP tabs choose 'Download From Radio'.
