I have BCB filters from I.C.E., both "receive only" ,and one rated for transceive operation, up to 300 Watts. The difference in size and weight is insignificant, to me at least.

To: "'FLEX USERS'" <[email protected]> Date: Monday, July 27, 2009, 1:59 PM 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?
