Thanks, Jim - great site.

While we're on the subject, does anyone have the QSK timings for any of 
the FT1000 range?

I'm trying to optimize the timings on a new PA control board that will 
support full QSK. I don't believe it will be possible to find one set of 
timings that will work with all transceivers, but the default settings 
obviously to be compatible with the entire FT1000 range.

The data required are:

In full QSK mode, and then in semi-BK mode (because it may be 
different):

1. Delay from first key-down to appearance of the fastest PTT output on 
the rear panel.

2. Delay from first key-down to first appearance of RF output.

3. With key locked down, but also a DIN plug in the BAND DATA socket to 
activate the TX ENABLE line... delay from grounding the TX ENABLE line 
to first appearance of RF output.

4. Delay between key-up and end of RF output.

Sorry that's a bit of a tall order, but I don't have any of those rigs 
here, and if you don't ask...

On the other hand, the whole lot takes less than a half-hour to measure 
(don't even need to take the covers off the rig) so if anyone within 
striking distance of Oxford cares to get in touch I'd be very grateful.

It would be interesting to develop a database of these timings for all 
makes and models of transceivers, which I'd be very happy to publish and 
share.
