340-degrees beverage daytime noise level. The peaks are semi-local Russian stations (and the very local "BV" NDB on 399 at extreme left)
The 340-degrees beverage (Western North America) was put up today. Unlike the other beverages it is lamp cord fed, not Twinax, and while the noise floor is at the same ultra-low level as the 50 and 310 degrees beverages, there are a few local noise peaks though not above -115 dBm. The jury is still out on the question should we replace the lamp cord with twinax.
