This is really for my own sake and probably not useful to others. Some geekery around local ham repeaters.

Signal reports are from a discone in my attic. Coverage predictions are from Radio Mobile Online, and bake in a whole lot of assumptions for something I generally don't have many details for, so don't take them with any seriousness.

Boston, 145.23

-105 dBm or so. A close-in hill leaves the signal a lot weaker here than it would otherwise be.

145.23 Coverage Prediction

Danvers, 145.47

-97 dBm

Waltham, 146.64

Received at -92 dBm. Pretty close to what models indicate. https://walthamara.org/about/repeaters/

Quincy, 146.67

-105 dBm

https://mmra.org/repeaters/QCY/

North Reading, 146.715

-91 dBm

Boston, 146.82

-109 dBm (weaker than I'd expect)

https://mmra.org/repeaters/BBY/

Derry, 146.85

-91 dBm

Westford, 146.955

-80 dBm. Receiver jumped between -80 and "> -80 dBm"

Paxton, 146.97

-108 dBm. Fairly weak.

IIRC the receive antenna is much higher up the tower so it might hear me better than I hear it.

Blue Hill, 146.985

-105 dBm

Billerica, 147.12

>-80 dBm

Marlboro, 147.27

-93 dBm received https://mmra.org/repeaters/MRW/#14727
