Bug#924867: w-scan: Does not scan for Polish MUX-8 (on VHF) channels

[Robert Luberda]

Package: w-scan
Version: 20170107-2
Severity: normal

According to a comment in w-scan source "VHF no longer used in Europe" [1].
However this is not true for Poland, which used VHF for channels in so called 
MUX-8, see [2].

I've checked today that simply uncommenting the line [1] and then
re-compiling w-scan did not work: even though such a w-scan 
seemed to scan 7MHz frequencies, its output did not contain 
any MUX-8 channel.

However when I downgraded w-scan to version 20130331-1 (using the deb
package from [3]), the `w_scan -c PL -X -f3 -E0 -R0' command was able to 
find all the MUX-8 channels:
