  • Spectrum to ham radio interface designs?

    From OldbieOne@21:1/5 to All on Sat Apr 10 16:10:52 2021
    Does anyone have a schematic for a basic ham radio interface for a Spectrum
    16 or 48k?

    Thanks

    Hi,
    back in the day we did things like transmit and receive SSTV, RTTY and
    CW using just the cassette input and output ports of the Spectrum withut
    any additional hardware interface.

    I remember that, but it didn't work very well for high impedence tube gear,
    and there were some isolation boxes out there, like the one from Technical Software somewhere in Wales, but that coimpany is long since gone
    apparently. Even if it's not, googling "technical software" leads to a dead
    end due to all the noise.
