There was quite a bit of activity on 40M tonight
Here is an example of a KE5 station who was weak – with diversity on. The UrbanBeam was on Ant1 – the transmitting antenna and fed to the main receiver, and the two KY6R Big Mag Loops are on the second receiver:
And then a stronger station up in Seattle:
I hope you can hear the difference.
80M was in even better shape – less noise than 40M
I noticed that 80M had less noise as we hit sunset. The noise on 40M increased , but it still was S7 instead of what it used to be – S9, making 40M pretty much unusable. It is now usable. So that goal has been reached.
This 80M sound clip is even better as far as showing the “bounce” between the UrbanBeam and the KY6R Loops. His signal is literally fading back and forth rapidly between the Inverted Vee and the loops.
I was very pleased tonight because I now have confirmed that the KY6R Big Mag loops do work better than the Inverted Vee and the UrbanBeam on receive. The loops were inexpensive and MUCH bigger and better than the commercial loops, the two preamps cost the same as about one commercial mag loop, the rotators were reasonable, and the NCC-2 was very expensive. HOWEVER – I can say with out a doubt, and shouting like an old man:
PUT ALL OF YOUR EFFORT INTO YOUR ANTENNAS. THAT AMPLIFIER WON’T HELP YOU HEAR THE WEAK ONES!
Nor will the amplifier eliminate your noise problem . . .
Between goofing around with BCB SWL DXing and playing on even just 160, 80 and 40M, I have already hit my goals and I am very, very pleased. Next I will try out 20M, 30M and eve above – to see how well this new RX system works there.
By the way, here is the Cady chapter on the K3 Diversity implementation:
