Paul, You don't have to do anything to share the mainRX with the subRX - the K3 will split the receive (through the 3dB splitter) to the main antenna for both receivers. That is good for SPLIT operation, but will not produce diversity receive. For diversity, you do need two antennas which

Interesting thread and one that I have a question on. I have three antennas coming in to the KAT3 and one jumper running from the KAT3 XMTR connector to my K3 Ant1. When I installed the KRX3, I made the choice to have the main and sub receiver share the antenna output of the KAT3. Since I had

Don, I have my sub receiver connected to the AUX input, and it still works just fine with diversity receive.  The way you do is connect your receive only antenna to the RX in BNC on the back of the K3,  then run a short piece of coax with male BNC connectors on each in between the RX OUT and

Some models of UHF under-dash Motorola mobiles have a short (+/- 6") TMP M/M jumper cable connecting two boards. A female circuit board connector can be salvaged from the the radio for use as a end connector on the short cable, making a M/F extension for the input to the 2nd receiver. I have the

Thanks for very quick responses to my question - I'm overwhelmed! I'll remove the top cover and start right away! I have two antennas, and no special receive antenna, and the two antennas are connected to ANT1 and ANT2 all the time. If I reroute the KRX3 AUX input to the KAT3, I will be able to

Sverre, That task can be accomplished by removing only the top cover. The angled TMP connector on the subRX is a little difficult to reach without tilting the back of the subRX up a bit, but it can be done. 73, Don W3FPR On 4/1/2016 1:56 PM, Sverre Holm (LA3ZA) wrote: When I built my K3

I put both cables in at build time. Unused one is routed into the shielded area and secured to the shield. Easy to re-configure. Take off top and change cables. A pair of surgical clamps may be useful. Sent from my iPhone ...nr4c. bill > On Apr 1, 2016, at 1:56 PM, Sverre Holm (LA3ZA)

Sverre, just curious, why would you like to route the 2nd RX through the KAT3? What is it that you trying to accomplish? Arie PA3A Op 1-4-2016 om 19:56 schreef Sverre Holm (LA3ZA): When I built my K3 some years ago I routed the second receiver's AUX antenna input to the rear panel BNC

When I built my K3 some years ago I routed the second receiver's AUX antenna input to the rear panel BNC connector. But now I have changed my mind and want to route it through the KAT3 instead, in order to try diversity reception. How complex is this to accomplish? I know I need to plug in
