- Tranceiver ICOM IC-729 -
Used this one on the 'FreeBand' in about 1996-1999. This is also an Fine radio! Got no problems with it! (Using one again 2014.06.29) - Now also used for digital application (MIL-ALE) from 2022 (Ongoing project)
2023.02.11 My software can't trigger the IC-729 in to TX via CI-V, and the radio lacks built in VOX function, so I now need some sort of VOX circuit. Found this schematics, i will try to build one a.s.a.p.
MC1458P DIP-8 dual op-amp datablad
PN2222A NPN General-Purpose Amplifier datablad
1N914 FAST SWITCHING DIODE datablad
2023.02.05 Changed CI-V settings on two(2) other IC-729 rig's - Added a few images for documentation.
Test after modification
Changes in the making / Made 'tags' with config data
Changing CI-V settings on the ICOM IC-729 radio
2023.01.08 Updated the CI-V settings on a IC-729 - Standard settings is: CI-V address 3AH, Baudrate 1200 with 5 data bytes. Need to change the settings to be able to use the radio with a specific software, the settings need to be:
CI-V address 3EH, Baudrate 9600 with 5 data bytes.
(makes the radio software compatible to MIL-radio Ra-763)
Sample calculation / CI-V Diode matrix on 'PLL-Unit' board
'D2' & 'D3' Baudrate settings
'D4' data format 4/5 bytes
This is what i did:
**Note: The user manual states the diode type to be '1SS133, 1SS53, etc' - I use 1N4148 diode, works fine!
Refer to original Instructions manual page 15 for more information.
