[Elecraft] RX Ant Preamps and the K3 12v Accessory Jack

[Geoffrey Mackenzie-Kennedy]

David,

Have you measured the strength of the BC carriers in the 6 MHz and 7 MHz 
"bands" after sunset as seen at the shack end of your antenna's feeder when 
terminated ?

If of any use to you I could send you some screen captures using a 1600 kHz 
span after sunset this evening, with the BC carrier levels marked. 7 MHz BC 
carrier levels received here off a 40m dipole under normal conditions 
usually reach + 5 dbm, sometimes a few db higher.

73,
Geoff
