A cositable ground radio for Have Quick and SATURN

When transceivers are closely situated, reception by one radio can be prevented by nearby transmissions from another. Classical filtering techniques are difficult to employ when the radios are operating in the Have Quick mode which employs slow frequency hopping throughout the 225 to 400 MHz UHF band. They are even more challenging when the SATURN fast frequency hopping system is used. The author examines the effects of desensitization, cross modulation, broadband noise, spurious output, and intermodulation products with a SATURN ground radio recently developed by ESD. It predicts both the Have Quick and SATURN performance which can be obtained when four radios are used in an MCE or TRC-87 shelter
