with this interface — eliminating the need for an external computer/radio interface for digital modes such as PSK31 or RTTY. A traditional ICOM REMOTE jack provides another means for control of the ’7200 from your computer if you have the appropriate CI-V interface and software. Jacks for ALC (automatic level control) and SEND (TR relay control) are available for connection to a linear amplifier. A TUNER connector provides an interface to control an optional external antenna tuner.

Keeping Track The IC-7200 is equipped with 201 memory channels. Channels 1 through 199 are memories that can store the transmit and receive frequencies and the operating mode. The remaining two (P1, P2) are band edge channels used as upper and lower frequency limits for the scanning feature. Programming the memory chan- Figure 4 — The rear panel of the IC-7200 includes nels is simple.
The NB will act on any strong signal and will distort a loud, nearby station so it should only be used when needed. The ’7200’s NB has two adjustments, level and width. These can be accessed directly from the NB key. NB level sets the level above which the DSP blanks out the noise spike; NB width sets the time the attenuation is applied. Lab Testing The bar for receiver performance in transceivers at all price points has been raised in the nine years since we reviewed the IC-718.
