Well, the original configuration (SteppIR controller passing commands between the radio and PW-1) worked… for a while. I suspect there was some collision or synchronization that fell out of timing…

I’ll spare the reader yet another glowing review for the Mini1300 analyzer. No I won’t – I’m still going to spew my thoughts on this thing.   I picked one up…

Today, I tackled interrupts. I’m not so sure I tackled interrupts, so much as i worked on determining the dynamic tuning step timing. I needed a routine to wait for…

Many years ago, programming the memories in an amateur radio was a “neat” feature.  As the capability was included in more radios, the radio manufacturers also began charging a hefty…
