+// transmitting on, because the DX's receiver was there a second ago.

+// Sending audio TO the radio over TCI.
+//
+// Three transmissions on a real SunSDR settled how this works, and none of it
+// was guessable from the documentation:
+//
+//  1. The radio asks for audio only when the transmission is the CLIENT'S. With
+//     the operator keying the microphone it sent 282 receive frames and nothing
+//     else, over six seconds.
+//  2. It asks only when its TRANSMIT AUDIO SOURCE is TCI rather than the
+//     microphone. This first read as "digital modes only" — SSB produced
+//     nothing four times over, DIGU answered at once — but the mode was a
+//     coincidence: ExpertSDR3 keeps that source setting per mode, and it was on
+//     the microphone in SSB. Which is why nothing is refused on the strength of
+//     the mode: the radio is asked, and it answers by asking or by staying
+//     quiet.
+//  3. The chrono is a REQUEST, not a clock to follow. It carries no payload —
+//     the message itself is the ask — and it names the size it wants in the
+//     header's length field: 2048 samples, two channels interleaved, arriving
+//     47 times a second. Which is 1024 sample-pairs at 48 kHz, exactly real
+//     time, measured rather than assumed.
+//
+// So audio is sent in ANSWER to chrono, never on a timer of our own. A timer
+// was the first attempt and the radio ignored every frame of it: 234 sent, none
+// used. Answering the request is what makes the difference, and it also means
+// the radio sets the pace — no drift, no buffer to tune.
+//
+// All of it was established with a tone probe — key the radio, push a sine,
+// watch — which is gone now that it has served its purpose: it answered the
+// three questions above, confirmed 80 W out on a real SunSDR, and had no

+//
+// # Transports
+//
+// KPA500: serial only.
+//
+// KPA1500: serial, and a network server. Four things may be connected AT ONCE,
+// which is unusual enough to design around — the Host PC USB port, the XCVR
+// SERIAL connector when repurposed as a second host, ONE TCP client, and any
+// number of UDP clients:
+//
+//   - TCP on port 1500 (changed with ^CP). Single client. If the operator
+//     already has the Elecraft utility or another program on TCP, OpsLog will
+//     not get in, and the failure is a refused connection rather than anything
+//     the amplifier says.
+//   - UDP on the same port. Many clients, one command per packet and at most
+//     one response, and packets may be dropped under congestion — so it is the
+//     right choice for sharing the amplifier and the wrong one for a command
+//     that must not be missed.
+//
+// # Pacing
+//
+// There is NO flow control. The reference is explicit: pace commands by waiting
+// for the response to the previous one. So this client is strictly
+// question-and-answer on one connection, like the ACOM and SPE clients, rather
+// than firing a poll cycle and sorting out the replies afterwards.
+//
+// # Serial speed
+//
+// 4800 to 230400, 8N1, set on the amplifier (^BR / SERIAL SPEED HOST) and not
+// negotiated. Elecraft's own utility finds it by sending bare semicolons at
+// each speed until something answers — worth copying if operators turn up with
+// amplifiers whose speed they do not know.
+//
+// # What is settled, and how
+//
+// From the KPA1500 Programming Reference:
+//
+//   - ^SW is the SWR IN TENTHS. "123 is 12.3:1", so ^SW015 is 1.5:1. This was
+//     first taken from Hamlib's backend and is now confirmed by the document,
+//     which matters more than it sounds: a wrongly scaled SWR bar reports a
+//     good match on a bad antenna.
+//   - ^WS returns forward power AND SWR together, ^VI returns PA voltage AND
+//     current together. Two round trips instead of four on the link the display
+//     depends on while the operator is transmitting.
+//   - ^SF returns the fault log: index, fault code, a short name in quotes, a
+//     timestamp, and fault-specific values. ^FC describes the codes.
+//
+// # Not touched
+//
+// ^TX simulates a KEY IN — it makes the amplifier transmit from software — and
+// ^ON0 switches the main supplies off. Neither belongs on a poll loop or behind
+// a button that can be pressed by accident.
