This site may help a few builders. I just came across it an hour ago and have had only a cursory look. It contains a lot of useful info on other topics as well. You need to scroll down to section 7. h

Hi Chris, I hope you can advise re the purchase of an LAA+ My intention is to use this indoors. The loop will be an inverted delta using the supplied wire and will be kept indoors in the first instanc

First of all happy new year to all.. my wife and I are recovering from covid..mother in law is in hospital..induced coma..so lets say DONT get this!! Its not good..fingers crossed for m in law.. It to

Hello Everyone, I am thinking of purchasing a HF/VHF/UHF Multicoupler and wonder if having a pre-amp in line with it would be OK? Thanks

Recently I've been working on using a Loop Antenna Amplifier + to make a cardioid loop antenna. I've already posted a few comments about it in one of the recent topics. I've now written it up as a new

The first of two new products this week. We've just released a HF Antenna Isolator. From the web page: It acts as a galvanic isolation transformer isolating the mains earth or ground at the station fr

Loop Amplifier as a Wellbrook replacement Hi everyone, As I/we are still recovering from Covid, I have been looking at improving the receive only antennas here. I have a CCW Active loop (the triangula

I am considering the CCW VLF loop amplifier for monitoring LW and MW broadcast stations as well as the 472kHz and 136kHz amateur bands plus NDB beacons. This will complement my home-brew Wellbrook clo

Over the last few days I've been revising the web site in preparation for the UK leaving the EU transition period on 31 December 2020. It allowed me to look at the web pages and realise that some of t

So it seems that there is FM broadcast interference using the SDRplay Bias-T throughout the HF band but it goes away when i use the 12V Bias-T power inserter you include as an option. Any ideas as to

Some complete @&@8 has put up some ( i hope.) dodgy xmas lights..s9+ all across the bands.makes the existing smpsu noise look silly! making yet another phaser..To phase this out?? i already hated xmas

Looking for ideas ( that i have not already tried,) for noise antenna to feed a phaser..in the attempt to null out a smpsu on 1845-1855khz.. this noise varies in amplitude and frequency depending upon

So, I've had my LAA+ for awhile but initially HF performance above say 5 Mhz was pretty disappointing. Below that I was quite happy with it's performance. With that said I'm back to the drawing board

Because I can I decided to see how the LAA+ performed at VHF when compared to a VHF/UHF discone. My set up is an RSP2 connected to a discone at about 4m AGL. CCW loop about 1m AGL. RSP1A is connected

Hi everyone. Just over a year ago, I bought a second-hand device on Ebay, which is labelled SDR-4+ HF/VHF receiver. It has a number on the side, which is 0350. All the seals seem intact. I'm one of th

Hi. Chris. Unfortunately I live in some retirement flats. I have now been asked to take down a loop antenna that I fixed onto the rear of a shed that been erected by a previous tennant. Here are the r

Hi, I know CCW do a low noise 12V power supply (which I have) but I am looking for a UK supplied 5V version to run the USB port of the CCW LAA+ base amplified PCB. Linear 5V supplies appear to be diff

Now I am on a quest to get better performance on 160m. To get more received signal strength from usa etc.. There is not much more I can do with my current loop..its big, switchable directions made of

Any info on this?? ie 160m dx LOW angle.. gnd mounted loop vs 5m above gnd loop.. can not find any info in net..atleast not for small active loops.. Simon

I find it quite embarrassing to ask this basic question, but here goes (with explanation). I have noted that on the design/schematic for the cardioid loop an earth is used. My simple question is wheth
