sync 2 Icoms via RRC-1258

[M0YEC]

Hi,

I just wonder if anyone tried to sync two Icom transceivers with the RRC-1258[MKII]. In detail, some Icom transceivers offer a feature called "CI-V Transceive"; here is how the manual of my IC-756III explains it:

"CI-V Transceive Transceive operation is possible with the IC-756PROIII connected to other Icom HF transceivers or receivers. When “ON” is selected, changing the frequency, operating mode, etc. on the IC-756PROIII automatically changes those of connected transceivers (or receivers) and vice versa."

I suspect one could also sync an IC-7000 and a IC-756 for example, but I have not tried. Anyway, if one TRX was placed at the control side and the other at the remote location, would it be possible to use the RCC-1258 to remote control one via the other?

Many thanks for your thoughts!!

Hi Christoph,

interesting thought! I haven't tried myself, so everything written below is pure speculation, but:

Synchronizing two Icom Rigs is done on the CI-V side, but as Icom CAT-Interfaces don't do anything other than level converting from TTL-level to RS232 level I would expect that connecting two CAT-Interfaces back to back will behave more or less the same than directly connecting CI-V. I use CI-V transceive with my remote IC-706MKIIG and a homemade CAT-Interface at the remote side tunneled via COM2 of the Remoterig-Boxes and that works perfectly for example with Win-Test and CAT switched to "Don't poll + Use CI-V tranceive". Unfortunately I don't have a second CAT-Interface with real RS232-port and therefore can not test.

I think you will have to use a Null-Modem-Type cable at the local side but haven't thought about that in detail yet.

Would be interesting to hear if you have success.

Good luck

Hi Simon,

many thanks for sharing your thoughts, which agree with what I would expect to happen. Unfortunately, I do neither own 2 Icoms nor the RRC, so I have no easy way to confirm that things actually work. However, I keep on trying to get the missing parts and will let you know about the results!
