Changing wifi country code in clover patch?

[Wurlitzer-1]

How would I go about changing the country code in this clover patch?
I understand I have to edit the <data> field, but all examples I can find describe the string encoded in HEX.

<dict>                    
  <key>Comment</key>
  <string>10.10.2+ 5Ghz US FCC, the-darkvoid</string>
  <key>Enabled</key>
  <true/>
  <key>Find</key>
  <data>QYP8/3QsSA==</data>
  <key>Name</key>
  <string>AirPortBrcm4360</string>
  <key>Replace</key>
  <data>ZscGVVPrKw==</data>
</dict>

If you open your plist in Xcode (or PlistEdit Pro), you will see how the find/replace are hex, but you can see what they are at Terminal too:

A???t,HSPEEDY-OSX:~ RehabMan$ echo -n QYP8/3QsSA==|base64 --decode|xxd
0000000: 4183 fcff 742c 48                        A...t,H
SPEEDY-OSX:~ RehabMan$ echo -n ZscGVVPrKw==|base64 --decode|xxd
0000000: 66c7 06[B]55 53[/B]eb 2b                        f..US.+

According to the guide, you replace the 55 53 (US) in Replace with the desired country code.

This post has details on country codes: http://www.tonymacx86.com/network/104850-guide-airport-pcie-half-mini-v2-117.html#post1027194

Simple matter of finding the country code you want, converting from ASCII to hex, and making the change in Replace.

For example, FR (France) would be:

SPEEDY-OSX:~ RehabMan$ echo -n FR|xxd
0000000: 4652

So you would set Replace: 66c7 0646 52eb 2b

Very clear explanation, thanks. Keyword here was base64.

So you would set Replace: 66c7 0646 52eb 2b

So once the country code is replaced in the hex string, convert it back to base64 like so:
$ echo "66c7 0646 52eb 2b" | xxd -r -p | base64
ZscGRlLrKw==

Use a plist editor so you don't have to convert between hex and base64.

For some reason, the thing hates FI as a country code. Can anyone deny or verify this? Symptoms seen are that in System Information there are listed all the supported channels. But once I attempt to connect, with FI set as a country code, I get the dialog about being unable to connect (and that I need to move closer to the AP). Then the 5 GHz channels disappear from System Information.

After that I will not see any 5 GHz access points until I reboot the hackintosh. If I stick with US, everything works fine, even though my AP is set to FI. The AP is set to use a fixed channel common to both country codes.

$ echo FI | hexdump
0000000 46 49 0a
0000003
$ echo 66c7064649eb2b | xxd -r -p | base64
ZscGRknrKw==
