Diversity Recieve Issue

This morning I was listening on 15 meters using ant2 which is hooked to one
of my verticals. I switched to ant1 (my second vertical) and I could barely
make out the signal. While still set to ant1 I switched to diversity
receive and I still could barely hear the signal in either ear. I then
switched off diversity, changed back to ant 2. I could hear the signal
again. I then switched to diversity while still on ant2 and I could hear
the signal well in both ears.

It seems like diversity receive is just giving me stereo receive of one
antenna, not true diversity receive of both antennas. What could I be doing
wrong? Am I missing a setting somewhere? I have the Config/Spkrs set to 2
and I have config/L-Mix-R set to A b. Just for reference, I do not have
matched filters in both receivers.

Re: Diversity Recieve Issue

Ken,

Matching filters is a good thing. You need to have both antennas hooked to the radio. I use the aux antenna for one and the main to antenna one. In bset, you select when pressing the antenna switch. Then I adjust the rf gain for each antenna to give similar output to the line out into my desktop stereo speakers.

Re: Diversity Recieve Issue

So does the receive antenna have to be on the aux port of the Receive Ant.,
IF out board (KXV3A) for diversity, or can it also be on Ant2 of the ATU
(KAT3-F)?

It is however it is wired. Some people connect it to the Aux jack,
others to the currently de-selected of ANT|ANT2.

The essence of the issue is that for diversity, each receiver must be
connected to a different antenna.

Re: Diversity Recieve Issue

In reply to this post by N3PSJ-2

You can use ANT1 and ANT2 if you have your sub RX plugged into the KAT3
board. Or you can use ANT1 and AUX_RF if you have your SUBRX plugged
into the AUX_RF BNC jack. Or you can use RX_ANT and ANT2 or AUX_RF.
The RX_ANT port can only be used on the main RX or both RXs at the same
time it can't be used on the sub RX only.

Re: Diversity Recieve Issue

Back to the original problem. I am pretty sure this is setting somewhere.
I have discovered that diversity works fine on 40 meters, but not on 20 and
15. On 40, if I am on diversity and I use and external coax switch on
antenna 1 and I switch out (disconnect) the antenna using the external
switch, the signal disappears in one ear. If I do the same thing on 20 or
15, the signal disappears from both ears. Any ideas?

Re: Diversity Recieve Issue

Ken,

The antenna selection is per band. Set up the other bands just like you
have for 40 meters.
