Not meaning to revive the dead, but is there an Amateur Radio that transmits on all bands and receives every frequency?
ALL bands? ALL Freqs? What does this mean? Unless you have equal space (and a few BILLION $$$) as underneath the NSA Ft Meade - I don't think so.
Amateur bands - yes. However usually only one received transmission at a time will come out the audio driver, and only one at a time (3 KHz wide with respect to others) can be transmitted legally with some significant tuning and adjustment required for each freq - whether receive or transmit. BTW - a frequency measurement is infintessimal. (sp?) Good question for most though. Sorry I don't have the time to explain thoroughly.
