Is the "simple diversity" feature that is coming in V1.3 for the 6700 only since it is the only model with 2 SCUs?

Al,

Every comment I read in the linked 160 DX thread required 2 SCUs to implement, even the "single antenna" arrangements.

Hi Mike,
In another post Steve mentioned they decided on the  "linked slice" method for the first pass at "simple diversity."   Since the 6300 and 6500 support multiple slices and one antenna, I wondered if that meant they were looking at something for all models.   As you noted the original thread mentioned using one antenna as a possibility also. 

It still may require 2 SCUs, I just couldn't tell for sure.  Here is a link to Steve's comments.

Mike,
Three was also one more place Steve mentioned the 6000 (and not the 6700 specifically) that made me wonder if they had a plan to address the other models....



Anyway it should be easy to resolve the question....

Al, it was just meant as good-natured word playing  ;-)  

The only diversity I know implies separate antennas to each receiver, so that would require a 6700.

The goal in basic diversity reception is to overcome multi-path fading by having one of the slice receivers able to "hear better" that the other at any given time.  In order to be "diverse" you need two independent RF signal paths.  This includes separate antennas (optimally diverse in polarity and separated by 1/2 wavelength at the operating frequency) and separate SCUs, so it is a capability only supported by the FLEX-6700.

This is one of two regrets I have that I was not able to afford moving all the way to the 6700.  (The other being extended coverage to 2 meters)  But the 6500 has enough other features that my regret is not excessive.  Besides, with the money saved I was able to buy some nice antennae!
