    Thanx, David.   I  looked at the launchpad url, which would probably
    be useful if it were rpm-based, as is PCLOS, but I don't think I
    could make use of a deb-based repository.
    PCLInuxOS (PCLOS) ultimately derives from Mandrake/Mandriva, but
    that was some time ago. It is rpm-based, like RedHat and Fedora, and
    apparently Centos.
    YUM and YAST are not supported; apt is supported at the lower level,
    and Synaptic at the higher level.  I looked briefly over the
    material at the trinityos url you mention. That's a big truckload of
    stuff! The folks at PCLOS warn against importing from outside
    sources, which has never stopped me from installing PROGRAMS from
    outside sources,
    but I am very leery about installing libs which might conflict with
    the lib system in place already in PCLOS. I basically do almost all
    computing in PCLOS, and I would not like
    to blow up the system!
    
    I believe that gqrx MAY be supported directly by Ubuntu, which I am
    not interested in pursuing 
in toto, but Mint uses Ubuntu
    sources, so perhaps I
    will investigate that, altho I really didn't want to have to go to
    another distro.
