Morning at the kitchen table

Kevin sits at the kitchen table with the shortwave radio and soldering iron laid out beside a spare front-end board, the shattered aerial still jury-rigged above the roof. Jenny stands at the door, one hand on the frame, the other cradling a mug of limpet broth, her bandaged ankle propped on a stool beneath a fresh sea-beet poultice. Through the open doorway the air carries a sweet, fermenting ripeness from the woods — mango and guava coming into season — while the tide, still low, leaves the dock pilings exposed and the northeast foundation trench quiet under the flat sky.

The air is heavy and still as the tide begins its retreat. Inside the cottage, the rhythmic drip from the leaking roof into buckets on the kitchen floor marks the slow morning. Kevin focuses on the delicate circuitry of the radio, while Jenny works on the sea beet sketches, letting the ink dry on the table.

Is the solder holding or is it just sitting?

Take a slow sip of the broth and trace the veins of the sea beet leaf in the notebook.

💭 peek at the thought

Two days until the boat. If the radio doesn't hold, I'll be out of antibiotics by next month.

Trace looks clean. Let me key the mic and see if the front end wakes up.

pick up the handset, key the mic on 2182, listen for receive noise and any reply

💭 peek at the thought

She's watching the joint I just flowed. Fair question — the iron's tip is shot and the flux is dry, but the trace looks clean under the loupe. I should test it before I say.

Check the frequency again, heat might have shifted it.

Lean against the doorframe and listen to the hiss of the speaker.

💭 peek at the thought

Static. It's always static or the wind.

Adjusting the trimmer now. Quiet on the speaker means it's hearing.

turn the frequency trimmer on the spare board slowly while monitoring the speaker for noise floor change

💭 peek at the thought

She's right — the board's been hot, the crystal could have drifted. I'll nudge the trimmer and listen for the noise floor to drop.

It's flat.

Tighten the grip on the pencil and shade the jagged edge of the sea beet leaf.

💭 peek at the thought

If I can't hear the boat, I'm just a ghost here.

No noise floor at all. Checking B+ on the preamp.

set down the handset, pick up the multimeter, probe the B+ test point on the spare board

💭 peek at the thought

Flat means the front end's dead quiet — no atmospheric noise, no static. Either the preamp isn't biased right or the RF path's open. Check the B+ on the board first.

Don't fry the board.

Set the mug down on the stool and shift weight carefully off the bandaged ankle.

💭 peek at the thought

He's chasing a ghost in the circuitry while the aerial is still a mess of wires and hope.

🔧 Kevin09:10

Just a voltage check. Probe's isolated.

touch the multimeter probe to the B+ test point on the spare board, read the display

💭 peek at the thought

She's not wrong — the traces are thin and the FET's gate is static-sensitive. I'll keep the probe steady and the voltage low.
