Phil: I measured the MDS on my radio (a beta, not a production unit but with all known issues fixed on the 6 meter amplifier) and it had an MDS of -130 dBm at 50.125.
While this is not deaf as a stone by any stretch of the imagination, I would suggest at least a 10 dB preamp, one of the newer ones from DEMI (with the improved IP3). The nice thing about this for the Flex5000 is this is seamless. There is a path for the insertion of same automatically into the receiver path, RXIN and RXOUT and all of this is handled automagically in the software by the user. This setting will work by band! I sent Richard Allen (W5SXD, SDR-1000 #1 owner) , a power spectrum of the bottom 192 kHz of the six meter band. No spurs, flat as the Bonneville salt flats. My radio puts out 95 watts on 50.125 MHz into my Bird 43 (with the 100w proper slug) into a 50 Ohm dummy load. The second harmonic is well below all required specs on my radio and Gerald has put an even better one (specifically for six meters) in the production units. he is really working hard to make this an excellent six meter radio. The transverter agility on the Flex 5000 is amazing. The OCXO in this thing is like the rock of gibraltar. This is a very expensive add on in most radios, it comes standard even in the A model. Thus I don't really need to inject my rubidium 10 MHz source into it but I do for the sake of perfection just to make sure that circuit is working. For your and others information, DEMI is back in business. They are answering the phone in Florida. Pardon me if I got all of my orders in before I passed this along. ;-).
