Scott, I get exactly the same numbers except on high where I get -124 dBm (my radio also calibrated against an XG1)

My pre-amp is set on low 2.) Level Meter reads S3 with -103 dbm (low) S2 -114 dbm (med) S1 -121 dbm (High) 3.) Selected filter on LSB 2.7K 7.200 hz 4.) Calibrated with XG1 This is into a dummy load or with SDR unhooked.

Slight diferences may occure on different bands. My readings with antenna disconnected on 14.250kcs and 500Hz cw are: on RX-Meter: on Panadapter: preamp high: ~ -142dBm ~ -153dBm med ~ -133dBm ~ - 143dBm low ~ - 124dBm ~ -135dBm off ~ - 114dBm ~ -125dBm As you can see I never reach the -104dBm Level. I get 104dBm Meter- reading when the preamp is off and the filter is set > 3.3kHz. Hope I could help with this. 73's Martin ----- Original Message ----- From: "Scott Gordon" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, August 17, 2006 1:16 PM Subject: [Flexradio] Signal to Noise >I am seeing on all bands into a dummy load or without a antenna connect >to the flex a S3 to S4 noise level or -104dbm.
