Icom IC-9700 and WSJT-X

The problem with new transceivers is the lack of support for drivers in programs like Ham Radio Deluxe, WSJT-X (OmniRig), N1MM+ and MicroHam drivers. Just to name some programs I juse often. After playing around I found a way using the IC-9700 with WSJT-X by emulating an IC-7300 wich has about the same architecture.

My IC-9700 settings:
MENU -> SET -> Connectors -> CI-V
CI-V Baud Rate: 19200
CI-V Address: 94h
CI-V Transceive: ON
CI-V USB Port: Link to [REMOTE]

When starting to make a QSO, check your audio level. Use the Meter section and be sure the ALC does not more more than 1, 2 or 3 blocks. If you’re running to much audio, the ALC will kick in, crating harmonics, splatter, etc. I’m sure people will just ignore your CQ, if they are able to make a decode anyway. Use the slider on the bottom right. In my case it’s set to about -25 dB.
For receiving: Use ALC slow and change ‘6 sec’ to ‘off’. This is by far the best setting to receive digital signals (also on the IC-7300) in crowded bands and it avoids strong signals (or people disrespecting the ALC setting, we call them egoists) wiping weak signals away.

The ALC should (almost) NOT come out of the (left) corner. Don’t mind the low power setting. My 500W SSPA requires only 4 Watts of input.

    note that the hamlib v4.x revision of 12 apr or so contains the basics for the 9700.
    Mike Black a fellow ham and I have been interacting to get it in.
