[TangerineSDR] EXT: Re: Magnetometer board

[David Waugh]

Good eyes for spotting the dual jumpers John! I kept two in place while soldering (for alignment). Hopefully it will work, a 10MHz signal from my tinySA seemed to suggest it does. The Bodnar GPSDO is supposed to be here today so I should find out for real. -David KE8QEP

I am also very interested in the magnetometer.At last week’s TangerineSDR zoom meeting I asked about availability of the magnetometer board and It sounds like there are not many of the boards still around, but a few people mentioned they might have some spares. If there is a board to spare, I would be more than willing to pay for the board, shipping etc. I live in a suburban neighborhood, and I assume there will be local influence from large trucks passing etc., but I would guess that some of those things can be filtered out and that some useful data can be produced. I did ordered the magnetometer module (RM3100) before realizing there was a shortage of boards (I guess I was too excited).Thanks, David KE8QEP
