27255 kHz 27.255 MHz 27258 27253 USB LSB via COMMSIGMA KiwiSDR

FSK data signals, at least two different stations (going by difference in signal strength) with some QRM from AM CB traffic down in the noise at 1700 UTC (1200 noon local time) COMMSIGMA KiwiSDR on the CT/MA border.  The band seems closed at this time so I am presuming this is the same 27.255 MHz data link FSK data burst network logged back in December.

Curious about these signals, Just purchased an SDR for my Dell Laptop. I hope to check it out! -Western NY.

They're likely telemetry links using 27.255 MHz with FSK modulation.  Under Part 95 of the FCC rules you can use up to 25 watts on 27.255 MHz...please do update us if you hear anything on these frequencies.  It will largely be dependent on what antenna(s) you use.
