[ICOM] IC7300 Smeter

[gfiber at comcast.net]

When I worked at Icom America, It's been 15 years since I left, most all the HF radios sensitivity met receiving specification with the preamp ON. . 
I have no idea how the IC-7300 is specified but your last post sounds correct 50 uV for S9 sounds reasonable with the preamp on. 
Best to check in the IC-7300 Service manual if one is available.

I'm not sure about the answer to your last question, perhaps someone else on 
the list may be able to answer your question.

ok, the Specification page show the sensitivity for preamp1 of -123dBm for 
10dB S/N and SSB bandwidth 
S0 should be -127dBm. The Specification do not say, that the S0 reading is 
-127dBm and S9 is 50 uV. 
So, is the S9 Smeter reading correct (50uV) with preamp1?
