[Elecraft] K3 Subreceiver KRX3 and Filter Lineup...

[Scott Manthe]

Phil,
I don' t think it is necessary to have the same number of filters in 
each receiver. My K3 main RX has 13khz, 6khz, 2.8khz, 500hz, and 200hz 
filters. My subreciever has 13khz, 2.8khz and 500hz filters. This gives 
me great flexibility with the subreciever and saved me lots of money, 
without sacrificing too much performance. My configuration still allows 
me to do diversity receiver on SSB and CW if I desire, and performs as 
well as almost every other amateur rig on the market. Other might 
disagree, but for me, because I'm on a budget, this configuration gives 
me a good balance of flexibility and performance in my subreceiver.

73,
Scott, N9AA
