K3s & Rx antenna
Locked
 
|
My order is in Queue for a K3s.
I currently have a K3 with sub Rx and have a HI-Z Rx antenna I use with the K3. Sometimes I like listening with only the Rx antenna, sometimes I like listening from the the Tx antenna. When I use diversity I want to hear from both the Rx and main antennae. With the K3, what I have done with the Rx coax is attach it to a T connector with one end attached to the BNC connector {27} Aux RF, located below ANT 2 and the other leg connected to the RX ANT - IN on the KXV3. Once I upgrade the two KBPF3 and Sub Rx board, I will migrate the Sub RX to the K3s With the K3s, how should I connect the RX antenna to be most effective with the K3s & diversity? As I have it now?

Hi Gary,
I don't know if it's right or wrong to do it the way you described. I chose to purchase a 2 port splitter from DX Engineering. Their part number is DXE-RSC-2. I suppose there are cheaper alternatives. http://www.dxengineering.com/parts/dxe-rsc-2 73, Mike K2MK

Gary,
You can connect it as you have it now, but you can simplify - just connect the RX antenna to the AUX RF BNC connector and then enter BSUB and select the AUX antenna input for the subRX. If you also want the RX antenna to feed the main RX when the RX antenna is selected, you will have to connect it as you have it for the K3. Those sections of the K3S work just the same as on the K3. 73, Don W3FPR On 2/9/2016 5:16 PM, Gary Smith wrote: > With the K3s, how should I connect the RX antenna to be most > effective with the K3s & diversity?

Replace the T connector with a hybrid splitter ... connect one output to the Aux Ant (Sub RX) and the other to the RF In (Main Rx). I like to feed the splitter with a RX antenna switch - each of the RX antennas plus a line from the RX Out jack. Ideally one would put a splitter on each RX antenna and feed separate switches for Main RX and Sub RX but that begins to get a bit complex (maybe someday with four outputs to route receive antennas to one of two transceivers <G>). You can build your own magic-T splitter from plans at Clifton Laboratories: <http://cliftonlaboratories.com/Documents/Notes%20on%20Building%20a%20Z10050A.pdf> I've used old "broadband" MATV/cable splitters (typically specified 10 - 1000 MHZ) from the "old days" with no issues all the way down to 160 although the isolation may not make full specs that low. If you need an off the shelf commercial product, look at the KD9SV unit: http://www.dxengineering.com/parts/svp-sv-rsc (less expensive than a lot of others). Or search for a surplus unit on eBay. 73, ...

Gary,
What I found works very well is to take advantage of the RX ANT IN and OUT BNC connectors. Connect your HI Z (or any other receive antenna - I have both the HI Z-8 and Beverages) to the RX IN BNC connector. Next find a short piece of coax (I happen to have a 2 ft or so piece of RG-400) with BNC connectors on both ends and connect one end to the RX ANT OUT, and the other in to the AUG RF IN connector. I have found this set up works well for both receive on either the transmit antenna or the RX ANT. When you switch to Diverse mode, the receive antenna will be on the man receiver, and your transmit antenna will be on the sub receiver.
