[Flexradio] 6 meters receive on 5000

With all of the great features of this radio, this is one of the very few 
shortcomings and it can solved with a $79 preamp from ARR.  The 5000A even 
has the preamp in/out BNC connectors on the rear panel so all you have to do 
is connect it and check a box in the Antenna dialog box.  Even cooler, you 
can specify the preamp gain, so the S-Meter continues to read accurately 
(and according to my calibrated HP signal generator, it is accurate to 
below -140 dBm) when the preamp is enabled.

6M is my favorite band and my 756 ProIII has been very lonely since I got 
the 5000A.  I just added a 2nd preamp to the RX2 input and am putting up a 
2nd 6M antenna today so that I can listen on both receivers at once (RX1 on 
the left ear and RX2 on the right ear).  Antenna 1 is 9el at 48' and antenna 
2 will be 7el at 95'.  I can look for beacons while monitoring the calling 
frequency or use it for diversity reception when signals are coming in at 
differing arrival angles.  Yesterday, with a single antenna, I was decoding 
FSK441 on 50.260 (RX2) while listening to the band starting to open on 
50.125 (RX1).  I could never do that with the 756 ProIII.  Also, the noise 
blanker really works.  I've copied Q5 signals that were 4 S-units below the 
power-line noise.

Don't let this one thing stop you from getting a really great radio.  I 
don't think you'll ever regret it.
