 |

Folks,
I have inherited an old Communications Specialists TR720 airband
handheld portable radio that has no transmit output and not so good
receive sensitivity.
Is there anyone out there that might have a service manual for this
unit? I would be willing to pay copying charges or if you trust me,
make a copy of your manual and send it back. And no, I haven't called
CommSpec yet, but I've got a sneakin' suspicion they won't have the
manual anymore.
Any help will be appreciated.

Folks,
I called Comm Spec and they cheerfully emailed me pdf files of the
radio's schematics and block diagrams. This was plenty for me to get
the radio working again.
I get the impression this list doesn't care much for radios and is much
more interested in the "fancier electronics" found in MFD's, navigation
systems, etc. I guess that's OK, but unfortunate when you consider the
FAA will be mandating conversion to digital comm radios in the not so
distant future. That should get folks excited.
