MODIFY YOUR ICOM R7000 TO SCAN AND SEARCH FASTER
Bob Parnass, AJ9S
This article describes how to increase the scan an
search speeds of the ICOM R7000 receiver by 60% without
noticeable performance degradation.
Background
The front panel SCAN SPEED control on the R7000
receiver allows the user to adjust the speed of scan-
ning and searching operations, as well as the rate at
which the priority channel is sampled. Rotating the
control counterclockwise decreases the speed, and rota-
ting it clockwise increases the speed.
When the SCAN SPEED control on my R7000 (serial number
001400) was turned fully clockwise, the radio would
scan a maximum of about 8 channels/second, or search
about 8 increments/second. As the following table
shows, the stock R7000 can scan about as fast as a
Radio Shack PRO-30 or PRO-2003.
