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.

http://web.archive.org/web/20010124070500/http://www.barc.org/barc/repeater.html had a lot more information than the current site.

145.23 Coverage Prediction

Danvers, 145.47

-92 dBm on new feedline (was -97 dBm)

Waltham, 146.64

-94 dBm

146.64 coverage prediction

Quincy, 146.67

-99 dBm

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

North Reading, 146.715

-90 dBm

Hollis, 146.73

-93 dBm with more noise than I'd expect

Boston, 146.82

-109 dBm (weaker than I'd expect)

Derry, 146.85

-91 dBm

Pembroke, NH, 146.94

-108 dBm. Honestly surprised it makes it down here.

Westford, 146.955

-80 dBm.

Paxton, 146.97

-108 dBm. Fairly weak here due to local topography.

https://www.cmara.org/meetings/presentations/Paxton_Repeater_Presentation.pdf -- says about 30W out. TX at 100', RX at 250'.

Blue Hill, 146.985

-105 dBm

Nashua, 147.045

-87 dBm

Billerica, 147.12

>-80 dBm

Marlboro, 147.27

-87 dBm received
