Auto Information mode

Many Kenwood and Elecraft transceivers support Auto Information mode. When enabled, AI mode causes the transceiver to output state changes as soon as they happen rather than waiting to respond to the next periodic poll. AI mode has the potential to allow an application or external controller to react much faster to state changes than periodic polling.

Has Elecraft ever considered implementing AI mode in the KAT500, KPA500, or KPA1500? It could allow external applications or controllers to "close the loop" almost as fast as Aux bus which is only available if an Elecraft transceiver is being used.

Re: Auto Information mode

Hi
A little trivia: The AI mode in the Elecraft radios is far from complete.
Only a small subset of commands are available.
On Yaesu radios, everything done on the radios is supported with AI and you
see orders of magnitude faster performance. In fact it is so fast that you
need to implement handshaking on the serial ports to prevent slower
computers from buffering the incoming commands. On a Hexa Core I7-9800 CPU
usage can hit 30% as it keeps up with all of the commands coming in when you
turn the VFO dial rapidly. The resting CPU usage is 1% since no polling is
occurring. The AI command is great especially since most of the traffic is
usually just the s meter. So very good meter performance.

Tom,

This will also be true of the K4.

I should have clarified: the K4 will exhibit 100% AI ("auto-info") control and far faster update speeds.

That's great.
Makes quite a difference.

You'll also get fast dB/bin data for external spectrum presentation, and streaming I/Q samples for external demodulation, etc.

Hi
I've seen parts of the programming interface and it looks quite good. I
think the K4 is posed to be one of the leading transceivers on the market
with its open, and well documented and supported programming interface.
Bring it on!
