How about trying a usleep in the get_if function in kenwood.c. And change
your PTT back to CAT control. If the IF command requires some "rest period"
this should fix the double-IF problem too.
static int kenwood_get_if(RIG *rig)
{
rig_debug(RIG_DEBUG_VERBOSE, "%s called\n", __func__);
if (!rig)
return -RIG_EINVAL;
struct kenwood_priv_data *priv = rig->state.priv;
struct kenwood_priv_caps *caps = kenwood_caps(rig);
return kenwood_safe_transaction(rig, "IF", priv->info,
KENWOOD_MAX_BUF_LEN, caps->if_len);
}
Change to
static int kenwood_get_if(RIG *rig)
{
int ret;
rig_debug(RIG_DEBUG_VERBOSE, "%s called\n", __func__);
if (!rig)
return -RIG_EINVAL;
struct kenwood_priv_data *priv = rig->state.priv;
struct kenwood_priv_caps *caps = kenwood_caps(rig);
ret = kenwood_safe_transaction(rig, "IF", priv->info,
KENWOOD_MAX_BUF_LEN, caps->if_len);
usleep(100000); // perhaps increase this -- 100ms may not be enough
return ret;
}

I don’t understand what you mean here Bill. Since the problem disappears when I
go back one revision, isn’t it fair to say that a WSJT-X change has, at least,
uncovered a problem in hamlib or the TS-480 firmware? I hadn’t updated hamlib
when I first saw the problem, and I haven’t updated the TS-480.

I’m running this way now, and it has now done 5 transmissions without a
problem. So far, so good!
But why/how does this double “IF” only manifest in r5700 and not in the earlier
revision?
