    Um, okay.

    The Cobra 139 is a 23-channel radio, not made since 1976, I think.

    Has fewer crystals than most 23-channel SSB radios. Only 11, if memory serves. Should shorten the list of crystals that have drifted too far off frequency for the trimmer caps to correct.

    Sams volume 59 is the only alignment procedure I have ever seen.
