why KRX3 SUB RX

[Jorge Diez - CX6VM-2]

Hello

 

Will appreciate any feedback about the use of the second RX on the K3

 

what are the uses for which it is essential to have the second receiver?

 

I think is not necessary to work on SO2V, right?

 

Thanks,

Jorge

Hola Jorge!

1.  Diversity RX.  I use Beverages on my Main RX and a RX4SQ on the Sub RX.  Useful for improving RX in one direction or listening in a different direction in contests.  

2.  Another nice application is using CW Skimmer to spot your TX frequency near the last station worked in a large split pileup.  You can even do this without listening to the pileup itself...only clicking on the last "599" on the Skimmer display.  See the last graphic below.  The only trick to doing this is that the TX frequency must be assigned to the Main VFO and DX frequency to the Sub VFO, since IF OUT always tracks the Main VFO (unless you do a hardware and software modification) so clicking the "599" sends your TX to that frequency.

Does anyone have any experience using multi-turn loop antennas with SGC¹s
(or other) antenna tuners?

SGC describes these in their book Smartuners for Stealth Antennas.  See

I have a K3 and live in a HOA community with significant antenna
restrictions, so I am looking for a small antenna.

Bob,
     I have a couple of SGC-230s. They do solve a lot of problems. Loops do work well. I have used them on and off for a long time.
     I don't know your situation, but if you have a "typical" house, whatever that is, I would suggest a trip to Home Depot and pick up some insulated stranded wire. The color should match the color of your roof. Run the wire as a loop along the periphery of your roof. Put the tuner at the feed point where it is hard to see, and then go for it. Don 't get anal over total length as the tuner will make up for bad numbers. Do not use RG-58 as your feed line. Use something like RG-8X, LMR-240, or good quality RG-8. This should work very well and will be almost impossible to see from the street.
