Thanks Craig. Maybe you're getting a bit of overload from the amplifiers, as the Conti loop can have a good sized output if you have locals nearby. The 1530 would deliver considerably less raw signal to its amplifier.

Yes, I remember that Seaside convention, glad that Grayland was all it had been cracked up to be. Heck, even hanging a loop off the motel balcony at that convention was pretty interesting. And now we're putting a DKaz out on the hotel lawn at conventions. Too bad the Pacific was so far away.

(and thanks for the JOUB posting)

I just received a couple of the KB-5 units from a gentleman in Maine who makes them. As you mentioned, I don't think the QB-18I transformers are in production any longer. I got them on Ebay many years ago. They are an 18:1 unit. The s/n difference was what was really pronounced. I live in a noisy area, which influenced my choice with the ALA 1530ln. Living as far inland as I do, I anticipated the need for amplification, as quiet as practical. The ALA 1530ln was so quiet compared to what I was accustomed to, that at first I thought something was wrong with the antenna. Further evaluation revealed that the s/n of that antenna is simply head and shoulders above anything I had used in the past. It was just behind the Conti loop as far as apparent gain and equivalent in the s/n category. I would add that I thought that the s/n of either the KB-5 or the QB18I was also degraded by the introduction of the DX Engineering RPA-1 preamp. The "cleanest", most intelligible signals were with either the ALA 1530ln, or the other two transformers without amplification. This was my first go at a vs b vs c testing, with me climbing up a ladder switching out antenna transformers during the brief window of TP signals present at this location. I must confess that a Grayland session right after the 2006 IRCA Convention hosted by Pat Martin at Seaside left a sustained and indelible interest in TP dxing on me! While health and other considerations influenced me to move back down to town from the mountains where bogs and EWEs abounded, I will continue to squeeze all of the blood out of this "turnip" that I can, hi!

 Interesting results
 Craig.   It sounds as if the FLG-100LN isn't

 functioning properly.  (first thought...power supply?)

 When you say "outperformed" was it in raw gain, signal to
 noise or ?

 I'm not familiar with either the  KB-5 or QB-18I.Â
 Are these no
 longer in production?

 best wishes,

 Nick
