Diversity RX Antenna Issue

Rich M5RIC

Hi

Am doing some testing with the diversity function (DIV) on my 6600M in Smart Control Mode and found an odd scenario.

Slice A - TX Antenna = ANT1

Slice D - Diversity Slice only used for Receive

No other slices are open.

If Slice A RX Antenna is on RX A or RX B then I go to change Slice D RX Antenna to XVTA or XVTA B it also changes Slice A RX too?

E.g. Slice A RX Antenna = ANT1, change to RX A, change Slice D RX Antenna to XVTA A, Slice A also changes to XVTA A.

If Slice A RX Antenna is on ANT1 or ANT2, I can change Slice D to any antenna, no issue there.

I'm aware the 6600 only has 2 SCU's but it seems there is some restriction here when trying to use RX A or B and XVTA A or B in Diversity?

Any help what I' missing would be great

Running 3.7.4

Thanks

Hi,

I have a similar question. I have Flex-6600M (v4.1.5) and a remote Flex-6600 (v4.0.1), the behavior is the same on both radios.

I have two antennas for TX/RX, connected to ANT1 and ANT2 respectively, and two antennas for RX only, connected to RX A and RX B. I thought I could use diversity reception on two bands simultaneously, e.g. ANT1 + RX A on 80m, and ANT2 + RX B on 40m. Apparently not. When diversity is activated on the first slice, the antenna selected for diversity reception follows the main RX antenna from the second slice and vice versa. When diversity is activated on the second slice, it’s diversity antenna follows the main RX antenna from the first slice. Thus, the diversity reception can only be used when there is only one active slice. Is this the way it is supposed to be?

Toivo—I am not certain but I think you are trying to monitor four antennas on a radio that will monitor two at a time.

Neil - yes, my bad. I had misunderstood the SCU concept a bit. It takes two SCU's to do diversity and that's exactly what the 6600 has. I got the explanation also from Tim, W4TME via helpdesk. The radio behaves exactly as it's supposed to.
