Hello Bill, I've been using the FLEX-5000A on 6m with an inexpensive 20 year old Radio Shack (Archer) 50Mhz - 450 MHz CATV preamplifier in the RX1 In/Out loop. It supposedly has 10 dB of gain, which is enough that connecting and disconnecting a 3-ele yagi pointed North (quietest direction for this QTH) produces about a 6dB diference in the noise floor. I'm sure it's a fairly lousy preamp for this purpose, but signals that were indicating S9 + 40dB were not causing any problems.
There are other contributors to this reflector who have more experience in this area than me, but I am quite certain that a decent preamp with no more than 10 dB of gain, in combination with the FLEX-5000 would make a terrific 6m radio for weak signal work. I plan on having some fun with it this weekend during the ARRL June VHF QSO party on 6m with the aforementioned preamp, and on 2m with an Elecraft XV144 transverter connected to the XVTX/COM port on the rear panel of the FLEX-5000A. What versatility! 73, Dale WA8SRA William Hein wrote: > Flex-5000 50-Mhz performance falls a little short for the weakest of > weak-signal DX.
