I currently live in a townhouse and have made an offer on a few acres in a
more rural area. I would like to measure the relative noise levels between
the two locations to reduce the probability of surprises or disappointments
should I close the deal. I have gotten access to a very good battery
powered spectrum analyzer and plan to use a tripod-mounted 6 foot whip and a
20 dB LNA to measure the noise levels at each location.
Hi Rick,
There are several good, inexpensive SDR receivers that plug into and are
powered by a USB port. The SDR Play1 costs about $130 at HRO. See
k9yc.com/KillingRXNoiseVisalia.ppt for a list of several others.
There's good freeware from multiple sources to produce excellent
spectrum displays and get RX audio out of a computer speaker. There's
also freeware for Android and iPhone. Also study the link above for what
sort of noise sources to look for, and how to identity the shources you
see.
