Re battery backup of the Pro-1 loops ... The power coupler supplies 20V DC (nominal) to the coax, and is normally powered with a 24V AC (RMS) transformer. It is possible to replace the transformer

I think the problem for UK and European users is that the Pixel can cost $700+ landed due to the shipping and the inport duties/tax etc. Regarding the reviews, the one on the Pixel website compares

Hi John, Interesting thread indeed ! Yes, I tried them both and then I read Guy's review. My conclusions fully match with his. My QTH is 12km / 7miles from a LORAN-C transmitter

An antenna? No sir, it's a giant "dream catcher"...

So, Dominique, you've tried them both and prefer the Wellbrook - or you interpret Guy's data and agree with his conclusion? Go to Pixel's site and you'll find the Pro-1 beats the Wellbrook. I wouldn't

That was an interesting read. Thanks!

Hi folks, Just have a look at this review from Guy Atkins: http://www.wellbrook.uk.com/reviews/ALA1530-vs-RFPRO-1AReview.pdf I fully agree with him ! Dominique Normandy, France De :

It comes with a "brick" style amplifier made by Clifton labs. This is a high quality design with good large signal handling and a 3 dB NF. Being connectorized, I can use it for other antennas. I like

Pretty pricey, but if I didn't have DIY skills, I'd certainly be looking at one. What the use of spending $800 odd dollars on a comms receiver, and feeding a noisy signal into it? You'd be far better

Can you indicate spacings available (for HV rating) and materials available. How long does the typical order take? Thank you

Hi VA6POP, Do you have a website where we can order? (I have some questions, if you can send me an email, that will be great.) Thanks! Kit AA6AS kwdgroups@...

I came face to face with one of these last week at the local candy store (HRO). Nice looking. Impressive up close. I should have asked them if they have it hooked up to one of the demo rigs. The

For one thing the Pixel Pro-1B is too expensive. Not a whole lot of hobbyists want to spend $500 for a receiving loop antenna, myself included. Why does it have to be so expensive? 73 - Todd WD4NGG

I have a Pixel loop that I want to put at the back of my 20 acres fed with a 1000 foot length of coax. I tried to ask the factory about that, and got a confusing answer. You need to address this

Hello one and all NEW Member here Just started working at Pixel Technologies http://www.pixelsatradio.com always looking for product feedback, suggestions, etc. I'm learning the product as I go -

I would not use LEDs as varactors. The LEDs act as photodiodes to some extent, generating noise. It's better to use a zener diode, if you have to. 73, Vojtech OK1IAK

Hans Summers has a decent writeup on using power diodes and/or LEDs as varicap diodes: http://www.hanssummers.com/varicap.html Dave

I can build for u any air variable capacitors Butterfly capacitor http://calgary.kijiji.ca/c-buy-and-sell-electronics-Butterfly-Capacitor-Rotor-and-Stator-Plate-Sets-VA6POP-W0QQAdIdZ563987077#

Kits and Parts (aka The Toroid King, aka 'Diz') sells the MVAM109: http://www.kitsandparts.com/parts.php Andy

I've done a number of remotely tuned antenna designs and the varactors I like to use have been the MVAM109 and MVAM115. But, those and their direct replacement, the NTE618, are difficult to obtain and
