VK0EK Four Year Anniversary

The 2016 VK0EK Heard Island DXpedition Wow – its been 4 years since the VK0EK Team were on their way to Cape Town to get the gear and ship fumigated and ready to make the long 11 day voyage to “almost” the South Pole – and way out there in the south of the Indian Ocean. I spent 3 years working with Bob, KK6EK…

ARRL DX Contest @KY6R

20 Meters was a huge surprise today – I worked 3 new QRP New Ones . . .  There was a great late afternoon opening – to both the Caribbean, and to Southeast Asia at the same time. I was very excited to be able to test the loops on 20M vs. the UrbanBeam – and guess what? The loops now perform the Diamond…

Key Learnings From My RX Antenna Project

1. For Receiving and eliminating man made noise, magnetic loop antennas are the way to go. While my Delta Flag modeled better in EZNec, the KY6R Big Mag Loop ran rings around it (bad pun intended). 2. Wellbrook offers a very nice set of different RX preamps, and while my favorite used to be the smaller ALA1530LNP, I can say without hesitation that my…

Wellbrook: My Favorite RX Antenna Preamps

When I say nothing beats a Wellbrook RX Preamp, I mean a remote preamp that is installed at the feedpoint of a magnetic loop antenna. The preamps in the NCC-2 are also very good as part of the NCC-2 architecture. However, I’m finding that the only preamp that is a must are the Wellbrooks. For weak signals I can’t use the preamps in the…

What I Want in a KX-4

After a walk in the Ham Radio wilds, I’m again a 100% Elecraft fanboy. The reason? “Extensibility and Versatility”. No other manufacturer comes close as far as being able to customize the radio to your requirements. If the KX-3 had two receivers as my new (used) K3 does, I wouldn’t have bought the K3. However, the K3 with KPOD and with the Xonar U7…

KY6R Big Mag Loop RDF = 9 dB

Two KY6R Big Mag Loops result in an RDF of 9 and a nice null off the back(s) Here is a nice chart of receive antennas and their RDF – https://www.k7tjr.com/rx1comparison.htm A classic loop pattern – this is with both antennas in line – pointed the same direction These larger loops do model better on 160 and 80, but are still OK on 40M.

W6LVP Loop vs. Wellbrook ALA1530LNP vs. KY6R Big Mag Loop

KY6R Big Mag Loops I’ve sold my W6LVP Loop. It’s a very good product, and pretty close to a Wellbrook ALA1530LNP, but I preferred the Wellbrook. I do NOT like having a coax loop – its floppy and when I compared a 24′ circumference coax loop to a 3/4″ copper tubing 24′ circumference mag loop – the larger copper tubing was noticeably better (no…

KY6R Big Mag Loops: WOW!

Two of these big boys sure makes a difference. The NCC-2 Preamps are also excellent! WOW – two of the same type of antennas sure makes a difference, and also – the 3/4″ copper is way better than coax for the elements – and these blow the W6LVP Loop out the door. The nulls are sharper, the small distant stations are much louder –…

KY6R Big Mag Loop

Two KY6R Big Mag Loops are up now . . . I haven’t done enough testing, but I have the full sized loops up with the NCC-2 phasing them. I have the 75 to 50 ohm and receiver guard and Preamp installed. It was more work than expected, but worth the effort. The testing begins

Super Loop Sunday and the Creepy Christmas Station – KLIB?

By 4:30 PM PST, the “All Christmas Music , All The Time” Creepy station fades away Mike, KJ4Z found KLIB using the Radio-Locator and says that sometimes AM radio stations will play something in automated fashion just as a “placeholder”. I know this to be true – because KPIG AM on 1510 out of West Oakland played on their AM transmitters while they were…
