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

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

Hello group, today, I needed to split HF signal from my Wellbrook ALA-1530LN. First I wanted to use a cheap low noise TV splitter which I have here in my drawer. Fortunately, I decided to put in on th

I had the original modified version and was very happy with it. I got used a lot. Then, while trying some antenna comparisons I managed to transmit into it and I killed it. After a few choice words ab

I've just had an email from Brian, 2E0TCU. He has bought a batch of the Ferroxcube toroids recommended for my recent loop counterpoise antenna design in the RSGB RadCom magazine. He is selling the sli

Following the publication of my recent article on loop counterpoises for low noise vertical antennas in the RSGB RadCom magazine, I've had a lot of feedback from RSGB members trying the design. One qu

We lost our incoming email service around 7 pm yesterday evening. We are not receiving any emails but can still send emails out as we uses a separate service for that. Regards, Chris

Hi Chris, Replied to your message regarding the loop amplifier and took the lid off. Just messaging here incase it drops into spam. Paul G0VKT

I have made some adjustments to try and reduce the noise on the CCW LAA+ loop. 1) Replaced the USB hub and USB cables (now short 0.3m ones) to my SDR's 2) Re-arranged the table to keep power as far aw
