BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - PROGRAMMING
Free Scroll Rx/Tx
Free Scroll Rx is a feature that allows a user to scroll through frequencies in a
receive-only capacity. If the “Free Scroll Tx” option is enabled, pressing PTT will
allow transmit on the selected frequency.
From the home screen tapping the channel frequency will open the Free Scroll
function.
This can be navigated in two ways:
• The directional buttons
The left and right arrow keys
change which digit is high-
lighted.
The up and down keys change
the value of the highlighted
digit.
• Tapping the digits
Note: The Free Scroll menu can be locked in the PRC-4090 Programming Software
and, if locked, will not appear when the frequency is pressed.
