[Flexradio] 5000A - BCB filter and 6M preamp in combo?

[Jim Barber]

For my uses (and until the 2M goodies come along) a BCB-blocking 
highpass filter and a 6M preamp are about the only things the 5000A 
really needs added to the front end. The receiver is otherwise truly shiny.

In order to address both needs without manual gadget-switching, it seems 
to me you could go about it one of two ways:

(1) Put the BCB-block highpass in the main feedline and an unswitched 6M 
preamp in the RX1 loop. This has the advantage of being simple, but the 
disadvantage/expense of requiring the BCB filter to be able to handle 
transmit power.

(2) Put the BCB-block highpass and a *switched* 6M preamp in the RX1 
loop. (single box?) Advantage being cheaper/smaller components in the 
BCB filter, disadvantages being the expense/complexity of bypass relays 
in the preamp stage and the requirement to switch the relay power off/on 
when changing bands HF-6M.

Opinions on which would be "better", or perhaps other alternatives?

Thanks,
