CWID with ARTS

The CWID feature appears to have a bug. It sends out the 'W' as a 'U' in Morse code. The
CWID feature, when enabled, transmits a CW identifier every 10 minutes when the radio
is operating in ARTS mode. Here is a set of instructions on how to test if your radio is
affected:
Go to menu item 11 and enter a CW ID string with some W's in it. To do this, press
Select knob and use the main dial to select the characters. Press the Select knob to
advance one character. Program all 8 characters using the Select button to advance. When
you get them all programmed, press Select again and the radio will playback the ID
you've stored. Use a tape recorder unless you think you can copy comfortably at 35-40
wpm. If you want to hear it on the air, proceed with the following instructions.
Go to menu item 10 and enable the CW id during ARTS operation.
Set the radio to a clear simplex FM frequency.
Press the FUNC key until you get to screen 3 which shows TON DCS and ART. Enable
ART.
Listen on another radio. The DCS code will be sent every 15 seconds and the CW ID will
occur every 10 minutes. Again, use a tape recorder, as the ID comes across at about 35-40
wpm. I have a little recorder that will allow me to record at 2.4 cm/sec and play back at
1.2 cm/sec so I can listen to the CW at a more comfortable 18-20 wpm.

Band Data Pigtail Pinout

The Band Data pigtail can control a VL-1000 amplifier when set internally to control an
amplifier. The normal mode is for the CAT/Tuner function, but it can be rearranged with
an internal jumper (shown on page 19 of the manual) to control an amplifier. If you're
curious about how the signals work in that mode, the table below shows the logic
depending on the band selected. The images to help explain this better are shown here.

CTCSS and memory functions

Storing CTCSS frequencies in memory along with frequencies is a bit tricky. When
putting frequencies into memory from the VFO you must have encode on and the display
